• FirePro is a flooding agent – the layout of the risk is relevent to the design.

• Review any openings or ventilation in the Risk and assess the impact on Fire System.
• The configuration of objects with special attention to the items which could initiate a fire.
• The use of the Risk – normally manned ?
• Clearances which need to be observed for safe egress from the Risk.
• Separate earthing of all devices is required in High Voltage environments.
• Clearances from objects for the FirePro units
• Methods for detection of a fire and activation of the Aerosol Generators.
• When selecting the particular FirePro units ensure even distribution of Gas – Stream Length?
• Bracket selection and consider the use of Heavy Duty Brackets.
• Wall or roof strengths compared the weight of the FirePro units.
• Use of Dust Covers on FirePro Units for protection from pest and debris.
• Signage Requirements – compliance issues and the system will be in place for many years.
• Self Activation temperature of 300°C NO welding grinding near units – once installed.

The FirePro electrical activation device is a small filament located within each aerosol generator.

The activator can be monitored by the system – this is done with a small amount of current through the activator circuit, this is measured by the panel to ensure that the circuit is complete. A fault indicator at the panel will advise if the circuit becomes incomplete for any reason.  The current required to activate the aerosol generators is small.

The presence of RF interference in the environment is very common it comes from many devices for example mobile phones, GPS devices, power invertors and many other sources.  This interference needs to be eliminated from any control system as it can cause malfunction.  The control panels and installation procedures that we use are all designed to eliminate any RF interference.

To eliminate the RF interference, SHIELDED FIRE RATED CABLE is required to be used on all Control systems.  In addition installations must comply with wiring rules AS3000 section segregation of different voltage levels.

The decision about compliance is a process which needs to be clearly identified.  This will be essentially at the direction of the client but will require your input as some risk areas could fall under multiple standards.  Knowledge of the standards and regulations is necessary to guide the client through this process.

Electrical using Integrated Control Panel – Need to ensure that panel will be selected to comply with relevant standard, and be capable of handling detection methods as well as number of Aerosol units in the system.

Simple Manual Switchrecommend that any switch is momentary action (not latching) and is protected against accidental operation.

FPC-2 – 24vDC panel has monitored circuits for FirePro units and detection.  Automatic & manual activation.  Fire & fault output relays.

System Panel – has monitored circuits for Firpro units and detection.  Automatic & Manual activation.

System Panel – has monitored circuits for FirePro units and detection, manual activation switch.

Standard AS Approved Fire Panel – signage and alarms are required.
Suitable for local protection systems only – not part of any AS Systems. Self-contained, automatic and temperature controlled activation system. The liquid within the bulb will expand until the required operational temperature is reached. At this point the glass bulb will ‘burst’, allowing the thermal mechanism to actuate the built-in firing pin, which initiates the ignition of the SBK solid compound in Generator activator.
