Why Choose the IMO FireRaptor FRS-ESW1-K Emergency Rapid Shutdown Switch?
The IMO FRS-ESW1-K is a key-reset emergency shutdown switch designed for the IMO FireRaptor photovoltaic rapid shutdown system. It provides a clearly identifiable and accessible control point for manually initiating rapid shutdown of connected solar PV strings, helping to reduce hazardous DC voltages during a fire, maintenance procedure or other emergency.
The unit combines an emergency stop control with an integrated 24 V DC FireRaptor control power supply. Pressing the emergency button interrupts the control supply to compatible FireRaptor shutdown devices, causing the connected PV modules or strings to enter their rapid shutdown state. The keyed reset arrangement helps prevent unauthorised or accidental restoration of the system after an emergency shutdown has been initiated.
Housed within a robust IP65-rated enclosure, the FRS-ESW1-K is suitable for accessible indoor or outdoor mounting. It is intended for residential, commercial and industrial photovoltaic installations requiring a dedicated FireRaptor emergency isolation point with controlled reset access.

Controlled Emergency Shutdown and Reset
During normal operation, the FRS-ESW1-K supplies the control voltage required by compatible FireRaptor rapid shutdown units. Pressing the emergency stop button removes this control signal, causing the connected shutdown devices to isolate or reduce the voltage produced by the associated photovoltaic circuits.
Following activation, the keyed reset mechanism restricts restoration of the shutdown circuit to authorised personnel. This is particularly valuable in commercial, industrial and publicly accessible installations where the solar array must not be re-energised until the emergency has been assessed and the system has been declared safe.
Typical Applications

- Commercial solar installations.
- Industrial rooftop PV arrays.
- Schools, hospitals and public buildings.
- Warehouses and distribution centres.
- Fire service emergency access points.
