fire raptor rapid shutdown

Best answer


TheIMO Precision Controls FireRaptor product is a Rapid Shut Down System for connection to PV panel arraysin order to achieve compliance to 2014 NEC 690.12 and the forthcoming 2017 NEC 690.12. The FireRaptor automatically shuts down array output to the PV inverter when it detects a temperature in excess to 85C (FRS-01) and 92C (FRS-02).

  • When does the fireraptor automatically shut down?

  • TEMPERATURE RISE TRIGGER: Automatic shutdown occurs if the temperature sensor onboard the FireRaptor detects an ambient temperature rise above 85藲C (185藲F). The FRS-01 shuts down only the panel (s) connected to it upon sensing an ambient temperature rise above 85藲C (185藲F).

  • How does IMO fireraptor shut down DC supply?

  • 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:

  • What causes the emergency rapid shutdown switch to turn off automatically?

  • 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藲C (185藲F).

  • Will the fireraptor work with my inverter?

  • 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.
