HD Fire System 2 Manual

A main water tank that can hold a specific amount of water.
The tank supplies water to the pump through the 'Tank Valve'.
This valve needs to be open to use the tank-water for pumping operations.
The pump can refill the tank through the 'Tank Refill'.
This valve needs to be open to redirect incoming water into the tank.

If the vehicle has a foam system then it will have a foam tank.
The displayed amount is the amount of foam concentrate.
The mix ratio is 3 parts concentrate with 97 parts water.

A pump panel, which has intakes and/or discharges.
Those can be large or small diameter connections.
The standard NextGen Pump Panel has:

• two large intakes
• two large discharges
• one small intake
• three small discharges

HD NextGen Tanker 13 features a smaller pump panel.

Up to two nozzles to spray water.
Those can be in the form of:

• - a deckgun
• - front bumper turret
• - aerial master stream
• - aerial piercing nozzle

A valve to quickly drop the water tank contents.
This is usually done into a Drop Tank.

Pump & Roll capability means that the pump is able to supply water while driving.
Most of the time this is done through separate discharges for dedicated Pump & Roll connections.
They can be either in the form of a Pre-Connect or small diameter discharge connection.
Pump & Roll connections do not have a visible hose line due to the frequent and dynamic positional changes.
Instead the connection is shown by particles with different colors:

• - gray for an idle connection
• - blue for a connection with water flow
• - white for a connection with foam flow

The HD Gear HUD is distributed by a centralized server within Second Life.
To get a copy of the latest version simply select 'Gear HUD' in the main menu of your vehicle.
The Gear HUD handles most of the equipment on the HD Vehicles.
You will not be able to use the compatible equipment without having the Gear HUD attached.
Some of the older equipment will still go directly to your inventory.

This is a simple extend-able ladder.
To use it, rez it in world and adjust the position and rotation through the build menu.
Touch the upper segment to extend it.
Touch the lower segment to retract it.

Cutters / Spreaders / Ram
These are various pressure powered tools used for rescue operations.
In order to use, please attach them to your avatar
Once attached, to operate them, you are required to connect them to a pressure source.

• A) One source is a Pressure Generator, in order to connect please attach the tool and
  click on one of the curved outlets located on the Generator.
• B) You can also connect them directly to the Heavy Rescue Apparatus by opening the
  
  passenger (right) side compartments and then clicking on one of the colored hoses
  (Located closest to the back).
  

Please make sure that the parking brake is applied.
Also ensure that you have the proper access rights for the truck/generator.
Next turn on the pressure source (click on the generator / turn on the engine of the Rescue unit).
You can operate the tools by using the page up and down keys.
They work within a 50m range to the source. You can click on the tool to switch between different poses.

The portable pressure generator can be used to power pressure based tools.
It has 2 curved outlets. You can click on the top of it to turn it on or off.

The portable electrical generator can be used to power tools and equipment that requires electricity.
It has 2 cable connections. You can click on the curved part of the cable to disconnect it.
You can start up the generator by clicking on the black t-handle of the pull cord.

To prepare a Rescue truck for a connection, trigger the parking brake and switch the apparatus to 'Pump Mode'.
Rez the light tower within 25m of the power source. Click on the light tower and select 'Connect' to establish a connection.
If no cable shows up then this means that you are either out of range or not allowed to connect.
You can turn the lights on / off via the same menu. Make sure that the power source is turned on.

This is a standard ABC class fire extinguisher.
You have to attach it to your avatar.
The gauge on the top of it indicates the current fill status.
Enter mouselook in order to use it.
It will spray for as long as you press the left mouse button.
The safety pin is automatically removed if you start spraying.
You can also remove it by hand by touching the ring of it.
You can refill the extinguisher by using the Extinguisher Refill Station.

If the vehicle offers SCBA refills then there will be a Refill SCBA button, given that there are still refills left.
Please check the menu info text to see the available amount of refills.
Selecting this option will refill the tank of your SCBA, given that you have it attached and that the tank is not full already.

If the vehicle offers SCBA refills then there will be a Restock SCBA button, given that the amount of refills is not at its maximum.
Please check the menu info text to see the available amount of refills.
Selecting this option will restock the amount of available SCBA refills the vehicle can give.
Please make sure that there is a SCBA Station within range, which has enough SCBA restocks available.

Hose Lines will connect to small and large diameter intakes and discharges.
The hose line will automatically temp-attach to your avatar when you select it.
Touch a intake or discharge connection to connect to it.
If it does not connect, then it might be that you do not have the rights to connect to it.
It will inform you if there is another reason not allowing to connect.
For example an Attack Line can not be connected to an intake.
The hose will be laid out automatically while you walk around.
To take a hose segment back in: simply touch it. You can only take in the last segment.
The range of each hose line is limited. Please check the hover text on your Gear HUD to see how much range is left.
If you want to take an entire hose line back in then you can:

• - touch the flexible part of the supply line in your hand
• - touch any s-segment at the end of the connection
• - click on the intake or discharge pipe your hose is connected to

Flexible Hose (Attack & Supply Lines) will inflate when there is a flow of water.
Rigid Hose (Suction Hose) is always fully round and will not collapse. In order to achieve a flow of water the source of the water needs to:

• - have the pump running if it has a pump (like a Pump Panel on a vehicle)
• - have the valve opened if it has no pump (like a Hydrant)

There are four types of Hose Lines:

• Attack Line
  
  An Attack Line will only connect to a small diameter discharge.
  You can use the page up/down keys to kneel down or stand up.
  To open the valve of the attack line you can:
  

  • - touch the valve on the attack line in your hand
  • - go into mouselook and use the left mouse button

  The attack line will spray foam when the discharge has foam injection active.
  The attack line will be affected by the GPM set for the source.
  
• Booster Line
  
  A booster line usually is a pre-connected hose that is stored on a hose reel.
  It is a special type of Attack Line, which uses the same controls. This type of hose usually has a lower GPM rating and shorter reach.
• Supply Line
  
  A Supply Line is used to connect an intake to a discharge.
  The order of connecting does not matter. The water will always flow in only one direction.
  There is a Small and Large Diameter Supply Line available.
  Either will only connect to the corresponding Small or Large Diameter intakes and discharges.
  
• Suction Hose
  
  A Suction Hose is used to connect large diameter intakes to an unpressurized water source. This water source can be a Draft Float, Drop Tank or Dry Hydrant.
  The hose will always be fully inflated as it is reinforced in order to allow drafting operations.
  In order to achieve a flow of water the water taking side needs to:
  

  • - have the pump running if it has a pump (like a Pump Panel on a vehicle)
  • - have the proper pump gear engaged (if it's not powered by an auxiliary motor)
  • - have a Suction GPM set

The Draft Float is designed to be put into natural sources of water.
It works with Linden Lab water in a region, as well as water objects.
Objects have to meet the following criteria:

• - named 'Water' (capitalization doesn't matter)
• - solid or phantom
• - not physical

While carrying the Draft Float, click on it to place it.
A check will be performed in front of you to find a suitable water source.

The Draft Float can not be used with the HD Drop Tank.
To draft water from the Drop Tank equip a Suction Hose and click on the Drop Tank.
This will automatically rez a compatible Low Level Strainer.

Once the Draft Float has been rezzed you can move it with the SL build tools.
A small light will indicate the current status:

• - red means that no water supply could be located
• - green means that it is ready for drafting operations

The Draft Float will automatically adjust its height-level to any water surface, given that it is within close range.
You can pick up a rezzed Draft Float by clicking on its handle.

The drop tank is designed to be dropped behind drop valves of vehicles.
It functions as water reservoir that can be setup at the scene.
Place the drop tank directly behind the drop valve.
The drop tank will automatically adjust its position for a perfect fit.
Please consult the manual belonging to the vehicle/object to see how to open the drop valve.
The drop tank will slowly fill with water when there is a stream of water incoming.
If it does not fill then it means that it is not correctly positioned.
Try moving the center of the drop tank exactly to where the water stream is going.

To draft water from the Drop Tank equip a Suction Hose and click on the Drop Tank.
This will automatically rez a compatible Low Level Strainer.
You can setup up to 4 connections with the drop tank.

Please be aware that once the drop tank is empty and will be refilled it will not update the flow of water for the connections.
This is because the flow of water has collapsed previously and the connection valve auto-closed.
Please restart the water taking side in order to get a flow of water again.

Couplers are used to extend the reach of Hose Lines.

• Attack Lines
  
  Attack Lines will automatically lay a coupler when the end of the line is reached.
  There can a maximum of two couplers and each coupler will lower the effectiveness and range of the water stream.
  
• Booster Lines
  Booster Lines do not allow the use of couplers.
• Supply Lines
  
  Supply Lines require you to manually select to lay a coupler.
  To do so click on the Coupler-Icon on your Gear HUD.
  
• Suction Hose
  Suction Hose does not allow the use of couplers.

Junctions are used to split or merge Hose Lines.
There are two types of Junctions available:

• Siamese
  A Siamese acts as a merger of two small diameter Supply Lines into a single large diameter one.
• Gated Wye
  
  A Gated Wye will split a large or small diameter Supply Line into two small diameter lines.
  Currently only the large diameter Gated Wye is available.
  You can connect either a Small Supply Line or Attack Line to either of those two small connections.
  Each outgoing connection has a lever which acts as valve to shut off either outgoing flow.
  

The HD Ground Monitor Set is available here.
A ground Monitor allows you to have a more flexible master stream.
You have to use a Supply Line to feed water to it.
The monitor has a valve to fully turn on or off the water stream.
The amount of water output is regulated by the water source.
If the monitor has a combination nozzle it will allow you to activate a fog pattern.
For more information please refer to the Manual.

The HD Portable Pump is available here.
The Portable Pump allows you to setup pumping operations almost anywhere.
It performs best for drafting operations in remote areas that are difficult to access with vehicles.
You have to use a Supply Line or Suction Hose to establish a flow of water to it.
The control panel has a valve to toggle the outgoing water stream.
You can also set the suction for drafting operations.
For more information please refer to the Manual.

The hydrant is used as source of water.
The flow of water can be configured to be between 300 GPM and 2000 GPM.
The top of the hydrant may be color coded:

• Red; below 500 GPM
• Orange; 500 to 1000 GPM
• Green; 1000 to 1500 GPM
• Blue; above 1500 GPM

The owner only menu offers a range of customization options.
You can change the color of the whole hydrant or select a special paint job.
You can also set the whole hydrant to be invisible if you want to use it as an overlay.
You may also create your own graphics by using the available Templates.

This Hydrant is only compatible with the HD Fire System 2.
Hydrants for Fire System 1 are no longer available or supported.

You can use a small or large supply line to connect to a hydrant.
You can touch the top of the hydrant to open and close the hydrant valve.

If a connected supply line is removed while the hydrant valve is open it will start spraying water.
The remaining connection will only receive 25% of the available water flow.
The other 75% of water will splash through the leaking connection.
To fix the situation you have to close and reopen the hydrant valve.

If two supply lines are connected to the same hydrant then the water will be split evenly.
A single large supply line can not take more than 1500 GPM.
A single small supply line can not take more than 750 GPM.

The hydrant can be run over by vehicles which were traveling fast enough on impact.
It will automatically repair after a minute has passed.
This feature is not available for invisible hydrants.

A Dry Hydrant functions the same as a static draft float.
They are most common next to lakes or on top of underground water tanks.
The pipe of the Dry Hydrant directly connects to the water source.
You need to use a Suction Hose in order to connect to a Dry Hydrant.

The refill pipes are used for vehicles that have a roof access hatch for the tank. Compatible vehicles: HD Titanium ARFF, HD Tanker 1.
The refill pipes can be used to refill water (blue) and foam (yellow).

The HD Powder Buckets comes as a set of 3 buckets filled with chemical powder.
They can be placed as needed and are most commonly stored on a shelf in a storage area.
You need to wear the Gear HUD in order to use the Powder Bucket.
Simply touch one of the buckets to grab one of them.
Walk over to the vehicle you want to refill and stand close to the refill position.
In most cases this will be a pipe with a purple cap.
Left click on the pipe to interact with it.
The contents of the bucket will be poured into the tank.
Empty buckets can be discarded by detaching them.
The Powder Buckets Set slowly refills itself at a rate of one bucket every minute.

The SCBA Station is used to restock the amount of refills a vehicle will offer for the SCBA.
Please check 'Refill SCBA' for details on the process.
You can refill the SCBA Station by touching the back of the cabinet.

The Extinguisher Station is used to refill empty fire extinguishers.
To simplify the process this station will refill A,B and C type extinguishers.
To refill an extinguisher make sure that it is the latest version and attached to your avatar.
Next right click on the Extinguisher Station and select 'Refill'.
Your extinguisher will move to the station and slowly refill.
In order to exit the refilling process simply stand up.

The HD Fire is used to light things on fire.
It is the main objective of the Fire System and has to be extinguished.

The Hose Packs can be used to grab an Attack Line, Supply Line or Suction Hose.
They are modify enabled and can be linked to vehicles or objects with modify permissions.
The Access can be set to Owner, Group or Anyone.

The Attack Line comes as set of two hose rolls with a Combination Nozzle and a Smoothbore Nozzle.
Either of the two hose rolls can be hidden or have its color changed via the menu.

The Supply Line comes as set of two hose rolls with a Small Supply Line and a Large Supply Line.
Either of the two hose rolls can be hidden or have its color changed via the menu.

The Suction Hose comes as single segment.
The color can be changed via the menu.

There are three bullet types:

• - Water Bullet
• - Foam Bullet
• - Powder Bullet

Based on the settings of the fire it will only accept specific extinguishing agents.
Foam and Powder Bullets are twice as effective as Water Bullets.
You do not need to use a specific object, the fire has no prim creator check.

Recommended settings for best results:

• - Prim Type Sphere
• - Identical X,Y,Z dimensions (this has a lower physics impact)
• - Default Transparent Texture from your Inventory Library
• - Buoyancy of 1.00 or lower to take gravity into account
• - Temporary
• - Physical

It's best to rez the bullets with a slow timer. Less active bullets mean less calculations for the server.
One bullet every 2.5 seconds should be sufficient to simulate a 350 GPM flow.

You may also use a power modifier to make the bullets more efficient.
You can add "@[float]" to the name of your bullet to modify the strength. The valid range is [0.25 to 10.00].
This is extremely helpful when creating very efficient extinguishing sources, like water drops from helicopters.
Example: "Water Bullet @ 2.00" would make your water bullet twice as effective.
Please use this feature responsibly. Unrealistic values can negatively impact the roleplay.

The bullets are temporary, so they won't survive for more than 60 seconds maximum.
To further reduce the physical calculations impact on regions:

It is possible to rez a fire with a lit state.

Use the script command llRezAtRoot to rez a copy of the fire by LSL script.

The on_rez event parameter can be used to determine if the fire will be lit.
Use FALSE or 0 to rez an unlit fire.
Use TRUE or 1 to rez a lit fire.

You can rez a default fire from your inventory and access the menu to setup everything the way you need it.
Take it back into inventory and rez that specific copy via LSL script.

It is possible to remotely control the HD Fires.
You will need basic scripting knowledge to use this feature.
Due to time limitations I am unable to give tutorials.
However I will answer technical questions. Just send your question via IM to Lares Carter.

To activate this feature open the menu of the fire and select 'Script API'.
Enter the channel the fire should listen to in the text box.
Leave it blank to close a previously opened channel.
Only one channel can be open at a time.
The owner of the sending object has to match the owner of the fire.
Child Fires will copy the channel of the main fire.

Messages have to be formatted like this: COMMAND = VALUE
Changes to the Script API with Update v2022.08.01 are highlighted in green.

• SET FIRE = ON / OFF / TOGGLE / KILL / RESET / LOAD
  
  KILL will remove the fire
  RESET will reset all settings to default, but keep the script API active
  LOAD will load the last given settings
  
• SET SMOKE = ON / OFF / TOGGLE
• SET LINGER = ON / OFF / TOGGLE
• SET SOUND = ON / OFF / TOGGLE
• SET ADVERSE = ON / OFF / TOGGLE
• SET STATUS BAR = ON / OFF / TOGGLE
• SET INFO TEXT = ON / OFF / TOGGLE
  same as SET STATUS BAR
  
• SET ADVERSE = ON / OFF / TOGGLE
• SET AGENT = Y / N / T (Water, Foam, Powder)
  
  Changes the accepted extinguishing agents (Water, Foam, Powder) for the fire.
  Y for Yes (extinguishing agent accepted)
  N for No (extinguishing agent ignored)
  T for Toggle (opposite of current setting)
  The command accepts up to three flags at the same time.
  They are applied to Water, Foam and then Powder in that order.
  Examples:
  "SET AGENT = YNY" Water and Powder, but no Foam.
  "SET AGENT = NNY" Powder only.
  Flags can be omitted to keep the current setting of the fire.
  Example:
  "SET AGENT = -Y-" Foam set to accepted, keep Water and Powder at what they previously were set to.
  
• SET NAME = [STRING]
  
  Renames the fire.
  
• SET LOCATION = INTERIOR / EXTERIOR / AUTO-DETECT
• SET EVENT = EXPLODE
  
  Triggers an event. Currently only EXPLODE is supported.
  If you have ideas for more useful events please consider filing a suggestion. Thank you.
  
• SET DAMAGE API = OFF / [INTEGER] @ [STRING]
  
  Sets the damage API
  First parameter is Channel, second parameter is Command
  Example:
  "SET DAMAGE API = OFF" disabled the damage API.
  "SET DAMAGE API = 25@FIRE-DAMAGE" sets channel to 25 and command to FIRE-DAMAGE.
  
• SET CHILD FIRES = REZ / [0 .. 10]
• SET DIFFICULTY = RANDOM / [1 .. 9] (1 Easy, 9 Hard)
• SET SIZE = [0.10 .. 2.00]
• SET MAX SIZE = [0.10 .. 2.00]
• SET ENERGY = [0 .. 200]
• SET BURN TIME = INFINITE / [1 .. 90] (in minutes)
• SET SCRIPT API = [INTEGER] / OFF (any whole number, can't be 1)
• SET SCORE API = [INTEGER] / OFF (any whole number)

Examples:

• "SET FIRE = KILL"
  Removes the fire.
• "SET CHILD FIRES = REZ"
  
  Will rez a child fire.
  Setting for child fires can not be 0.
  The last rez has to be at least 30 seconds ago.
  
• "SET SIZE = 1.25"
  Sets the size of the fire to 1.25.

Caveats:

To detect a lit fire please scan for objects with the name 'SMOKE'.
The HD Fire will rename itself to SMOKE every time it is lit.
The setting for smoke and linger being visible or invisible has no influence on this.
The name is also set to SMOKE while linger particles are present after the fire has been extinguished.
While passive and not burning it will rename itself to 'HD Fire (Version)'.

The Damage API requires a channel and command.
When an avatar collides with the fire while it is burning then the command will be sent to the avatar on the channel via llRegionSayTo()
This can be used to create Health HUDs that trigger avatar damage when walking into flames.

The command supports the following placeholders:

Example: "FIRE-DAMAGE@[AVATAR]" will send the message as "FIRE-DAMAGE@6727ab79-7a3e-4473-9e3b-af762883eaa9" for Lares Carter

The Score API requires a channel.
When an accepted bullet collides with the fire or when the fire is extinguished then a command will be broadcast on the channel via llRegionSay()
This can be used to create Score HUDs that award points and rewards for fighting and extinguishing fires.

Accepted Bullet Collision
Command: FIRE-HIT@[AVATAR]
[AVATAR] will be replaced with the UUID of the owner of the bullet.

Fire Extinguished
Command: FIRE-OUT@[AVATAR]
[AVATAR] will be replaced with the UUID of the owner of the last detected bullet.

Example: "FIRE-HIT@6727ab79-7a3e-4473-9e3b-af762883eaa9" will be sent when Lares Carter hit the fire with an accepted bullet type.
