FireRaptor Overview

The IMO FireRaptor provides three forms of Solar Panel Rapid Shutdown to ZERO VOLTS in case of fire or other emergency:

  • MANUAL EMERGENCY SHUTDOWN
    Manual shutdown is operated via an Emergency Rapid Shutdown Switch utilising a typical “one push” large emergency push button. The switch can be conveniently located anywhere for emergency access and is supplied with a 24VDC power supply to interface with the FireRaptor units.
  • AUTOMATIC EMERGENCY TEMPERATURE SHUTDOWN
    Automatic shutdown occurs via the temperature sensor onboard the FireRaptor detecting an ambient temperature rise in excess of 85°C (185°F). In the event that the temperature exceeds 85°C (185°F) the FireRaptor will act to shut-down the PV panels as follows:-

    FRS-01 – Shuts down the panels connected to the individual FireRaptor sensing the temperature rise above 85°C (185°F). The FireRaptor will re-engage the panels if the temperature drops back below 85°C (185°F) provided it does not exceed 92°C (198°F), in which case a manual reset of the Emergency Switch is required.

    FRS-02 – Shuts down the entire string in which the individual FireRaptor sensing the temperature rise above 92°C (198°F) is connected. If this occurs a signal is sent to the Emergency Switch and resetting of the Emergency Switch is then required by a professional installer. The Emergency Switch can be configured to provide connection to the building’s central alarm system or notification via mobile commincation (SMS, email etc.).

  • AUTOMATIC EMERGENCY EXTERNAL POWER LOSS SHUTDOWN
    Disconnection of the external AC supply, by whatever means, causes automatic remote operation of the Emergency Rapid Shutdown Switch.

The FireRaptor can be installed without any set-up and with any string inverter as its functionality is completely independent. “Plug & Play” style installation using industry standard connectors is easy, whether fitted to new installs or retro-fitted to existing projects to upgrade fire safety functionality.

The FireRaptor meets the current requirements of 

FireRaptor Installation

One FireRaptor will control two solar panels. The diagram below illustrates an example of a 2kW FireRaptor protected installationusing eight 250W solar panels and four FRS-01 FireRaptors.

The Emergency Rapid Shutdown Switch can be installed at a convenient ground level location providing easy access during emergencies. Alternatively, multiple switches can be installed in different multi level building zones.

Disconnection of the external AC supply, by whatever means, causes automatic remote operation of the Emergency Rapid Shutdown Switch.

Emergency Shutdown Switch

The Emergency Shutdown Switch for both the FRS-01 and the FRS-02 is supplied with a 24VDC power supply suitable for up to 40 panel operation. It is available with either a “twist-to-release”pushbutton or keylock pushbutton, both with LED indicator to signal FireRaptor supply status (ON indicates the supply is live).

For larger installations, the Emergency Shutdown Switch is available in custom format with:

  • Larger power supply options for increased number of panels (FRS-01 & FRS-02)
  • Multi connection terminals for increased number of strings (FRS-01 & FRS-02)
  • Temperature monitoring unit with hardwire or mobile communication alarm signalling (FRS-02)

Contact IMO for further information on any of these options.
