Gas detector CG8

wall-mountedcommercialwhite

To actively detect gas and control gas valves / alarms. may cooperate with eight gas sensors memory of alarms generated diode indicators continually visualize the highest gas concentration in the system monitored battery remaining operational during power cuts for up to several hours continuous monitoring of correct gas sensor operation indicator / actuator testing function units may be linked to increase system capacity alarm warns against excessive gas concentration and cuts off gas supply alarm signal may be transmitted to external systems sensors protected against short circuit with semiconductor devices inputs protected against interferences / voltage surges conformity with harmonized standards for gas devices and with EMC / LVD Directives Device controlled fan, gas cut-off valve, alarm circuitry Power supply 230 V 50 Hz Back-up batteries 7,2 Ah gel battery Number of gas sensors 8 Gas sensor type 4…20 mA linear current loop corresponding to 0…20 % LEL (Lower Explosion Limit) Alarm threshold 20,3 mA ± 2 % Fuse 1 A (slow) Fan output voltage-free NO contacts (rated load 3 A 230 V 50 Hz) Alarm output voltage-free NO contacts (rated load 3 A) Electrically held gas valve output12 VDC, rated load 1.3 A (16 W) Status visualization LED diodes Operating temperature range +10 °C…+30 °C Storage temperature range +5 °C…+40 °C IP rating IP 22, class II protection against electric shocks Colour gray Mount method wall-mounted, wall plugs Weight 5,58 kg Certificates/standards complies with the EMC and LVD Directives, and with the PN-EN50194:2005 standard Type 2 according to the PN-EN50270:2005 standard
