The OBFRS-01 is designed to shutdown two panels or it can be mounted in single panel configuration if preferred. The IMO FireRaptor shuts down DC supply at panel level to ZERO VOLTS in case of emergency. Shut-down is initiated in three ways - Manual Operation, External Power Loss or Temperature Rise Trigger as follows:
MANUAL OPERATION: Manual shutdown is initiated within less than 1 second of operation by pressing the emergency pushbutton on the Emergency Rapid Shutdown Switch (Part no FRS-ESWx). The Emergency Switch can be conveniently located at ground level for easy access or multiple switches can be installed in different multi-level building zones.
EXTERNAL POWER LOSS: Disconnection of the external AC supply, by whatever means, causes automatic remote operation of the Emergency Rapid Shutdown Switch and panel shutdown.
TEMPERATURE RISE TRIGGER: Automatic shutdown occurs if the temperature sensor onboard the FireRaptor detects an ambient temperature rise above 85˚C (185˚F). The FRS-01 shuts down only the panel(s) connected to it upon sensing an ambient temperature rise above 85˚C (185˚F). Provided the temperature does not exceed 92˚C (198˚F), the unit will re-engage the panel(s) if the temperature drops back below 85˚C (185˚F), otherwise a manual reset of the Emergency Switch is required.
Inverter Compatibility: The FireRaptor operates in the same way as an isolator/disconnect switch but is located at solar panel level. Like an isolator/disconnect, the FireRaptor is compatible with all string inverters and does not affect their operation or performance in any way.
