Multi-band flame detector


PPW-40REx detector provides high flame detection efficiency of fuels containing hydrocarbons, while maintaining a high immunity to false alarms due a set of three infrared sensors operating in different bands.

It is intended for use in potentially explosive zones - a flameproof construction. Detector is designed for indoor and outdoor application.

The detector is designed to be connected to such control panels that can receive an alarm signal from potential-free relay contacts, as well as cooperation with other systems using the 4 - 20 mA current loop.
