FireRaptor Overview

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

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 tted to new installs or retro-tted to existing projects to upgrade re

safety functionality.

The FireRaptor meets the current requirements of

2017

 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 congured to provide connection to the building’s central alarm system or notication 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.
