Kits composed of Sicurgas gas leak detectors P21 – P22 and safety solenoid valves normally open or normally closed. Available for methane gas and LPG detection. GAS LEAK DETCTORS P21 – P22Shockproof insulating material casing. Internal visual and acoustic alarms. Sicurgas has three warning lights: green LED – indicates that the detector works properly, yellow LED – indicates detector failure, red LED – indicates the gas presence in the environment (ALARM). Semiconductor sensor for gas detection (can be replaced). Sensor life time approximately 5 years from installation. The used relay is sealed and filled with inert gas, which ensures in any case the absolute absence of sparks during switching phases. Internal switch for choosing the functioning mode of the relay: stable or impulse. Electric featuresGAS LEAK DETCTORS P21 – P22Power supply: 230Vac 50Hz. Consumption: 4 VA.
