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.
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.

The FRS-ESW1-K is an emergency shutdown switch with a key-controlled reset, designed for use with compatible IMO FireRaptor photovoltaic rapid shutdown equipment.
The keyed reset helps prevent unauthorised or accidental reactivation of the photovoltaic system after an emergency shutdown has been initiated.
Pressing the emergency stop button interrupts the 24 V DC FireRaptor control circuit, causing compatible rapid shutdown units to enter their shutdown state.
Yes. It incorporates an internal 24 V DC power supply for compatible IMO FireRaptor rapid shutdown devices.
Its IP65-rated enclosure is designed to provide protection against dust and water ingress, making it suitable for appropriately positioned indoor or outdoor installations.
The switch should only be reset by authorised personnel after the reason for the shutdown has been investigated and the photovoltaic system has been confirmed as safe.
The IMO FireRaptor FRS-ESW1-K provides a visible and dependable photovoltaic emergency shutdown point, with key-controlled reset access for improved operational control and safer restoration following an emergency.{ "@context": "https://schema.org/", "@type": "Product", "name": "IMO FireRaptor FRS-ESW1-K Key-Reset Emergency Rapid Shutdown Switch", "sku": "FRS-ESW1-K", "mpn": "FRS-ESW1-K", "brand": { "@type": "Brand", "name": "IMO Precision Controls" }, "category": "Photovoltaic Rapid Shutdown Switches", "description": "IMO FireRaptor FRS-ESW1-K key-reset emergency rapid shutdown switch with an integrated 24 V DC control power supply and IP65 enclosure for photovoltaic safety systems.", "additionalProperty": [ { "@type": "PropertyValue", "name": "Reset method", "value": "Key-controlled reset" }, { "@type": "PropertyValue", "name": "Input voltage", "value": "90-264 V AC" }, { "@type": "PropertyValue", "name": "Control output", "value": "24 V DC" }, { "@type": "PropertyValue", "name": "Output power", "value": "10 W" }, { "@type": "PropertyValue", "name": "Protection rating", "value": "IP65" }, { "@type": "PropertyValue", "name": "Compatible system", "value": "IMO FireRaptor Rapid Shutdown System" } ] } { "@context": "https://schema.org", "@type": "FAQPage", "inLanguage": "en-GB", "mainEntity": [ { "@type": "Question", "name": "What is the IMO FRS-ESW1-K?", "acceptedAnswer": { "@type": "Answer", "text": "The FRS-ESW1-K is an emergency shutdown switch with a key-controlled reset, designed for use with compatible IMO FireRaptor photovoltaic rapid shutdown equipment." } }, { "@type": "Question", "name": "What is the purpose of the keyed reset?", "acceptedAnswer": { "@type": "Answer", "text": "The keyed reset helps prevent unauthorised or accidental reactivation of the photovoltaic system after an emergency shutdown has been initiated." } }, { "@type": "Question", "name": "How does the FRS-ESW1-K initiate rapid shutdown?", "acceptedAnswer": { "@type": "Answer", "text": "Pressing the emergency stop button interrupts the 24 V DC FireRaptor control circuit, causing compatible rapid shutdown units to enter their shutdown state." } }, { "@type": "Question", "name": "Does the FRS-ESW1-K include a power supply?", "acceptedAnswer": { "@type": "Answer", "text": "Yes.
