Product Description

Emergency Shutdown Switches

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

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 (FRS-ESW1). 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 panle 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 two FireRaptor versions available shutdown in different ways.

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.

Other IMO FireRaptor Components

The FRS-SIGCAB1.8-F is a cable assembly with a connector on one end that plugs into the first FireRaptor and is hard wired into the array j-box on the other end. It adds another 71 inches in length to the lead on the first FireRaptor.

The FRS-ESW1 is an Emergency Shutoff Switch that is used to turn the solar array on and off. It comes with a 120 VAC to 24 VDC power supply capable of powering up to 40 FireRaptors. If the 120 VAC power to the unit is off the system will shutdown automatically. If the manual button is pushed the system will shutdown. A 48 VDC to 24 VDC power supply can be substituted for the AC to DC power supply that comes with the ESW1 for a more reliable manual shutdown for systems with backup power. Emergency shutoff switches from other systems can be substituted for the ESW1. For OutBack this can be the RSI, and for MidNite the MNBirdhouse. Using the Aux contact closure in those switches will shut off power to the FireRators on rapid shutdown, serving the same purpose as the ESW1. This is helpful for systems with charge controls that require a disconnect at the charge control end of the circuit because the FireRaptor system will not serve that function directly.

If your modules will never exceed 40 VDC under any conditions, you can use two modules in series for each FRS-01 unit (code requires a maximum of 80 VDC in the array on shutdown). The FireRaptor FRS-01 does not have any monitoring or optimization.
