FFE Fireray Anti-Condensation Prism Heater (Black) (5000-205)

The Fireray® prism heater is designed to be used in environmental conditions where condensation affects the reflector of the optical beam smoke detectors. The heater will reduce the likelihood of condensation by maintaining the reflector at a higher temperature than the surrounding air. The heater pad is an efficient, ultra-slim heating pad which is fixed behind the mounting plate.

Condensation occurs when the surrounding air is at a higher temperature than the surface that it comes in contact with. As air contains water, typically in the form of vapour, this will deposit on the cooler surface thus forming condensation.

The Fireray® prism heater increases the temperature of the prism through the mounting plate thus maintaining the reflector at a higher temperature than the surrounding air. This reduces the likelihood of condensation forming on the reflective prisms which, in turn, reduces the potential for false alarms.
