Product Spotlight: FireRaptor PV RSD

Introducing the IMO FireRaptor - the ultimate solar panel rapid shutdown solution.

Solar panels produce DC electricity, unlike AC supply which passes through 0V at least 50 times per second and has a pulsating characteristic, DC supply is constant in its effect. Combine this with the fact that the absolute current value often used in solar installations is much higher than typical consumer AC supply, and it is not difficult to understand what makes solar installations a potential source of grave danger to Fire Fighters around the world.

In cases of fire in buildings with solar installations present, the panels continue to produce energy as long as there is daylight present, so it is critical that the live DC wiring in and around the building is isolated as close to the panels as possible. The FireRaptor isolates the DC wiring directly behind the panels. Each FireRaptor operates two solar panels and is positioned behind the panels and attached to the panel mounting frame. The FireRaptor is rated at 700W, so is suitable for most types of solar panel currently available on the market.

IMO FireRaptors are connected in series using plug-and-play connectors and the signal cable is then taken to the Emergency Switch, which can be situated anywhere inside or outside the building. As soon as the Emergency Switch is activated, the FireRaptor "shuts-down" the solar panels by isolating all the DC cabling in the building right back to the rear of the panel installation. In a larger, multi-storey building, a number of Emergency Switch units can be located in multiple zones around the building, or on different floors as required.

Automatic Shutdown

Although the FireRaptor can be shut down manually, it also offers two different types of automatic shutdown, as follows:

Automatic Emergency Temperature Shutdown: Automatic shutdown occurs if the temperature sensor onboard the FireRaptor detects an ambient temperature rise above its programmed trigger level of 87°C (188°F).

Automatic Emergency Power Loss Shutdown: Disconnection of the external AC supply, by whatever means, causes automatic remote operation of the Emergency Rapid Shutdown Switch and solar panel shutdown. A great feature for Fire Fighters where building AC mains disconnection is standard practice upon arrival to a fire related emergency.

Now available with hardwire or remote alarm signalling

The Emergency Switch is supplied with the power supply built-in and is available in both standard emergency push-button or key-operated format, and now features an optional fire monitoring and integration functionality which enable either hardwire or mobile communication alarm signalling.
