JA-80G Wireless Gas Leak Detector

The mains-powered JA-80G senses combustive gas leaks using a hot platinum filament sensor. Wirelessly signals to alarms with a relay output to shut down electric gas valves. Enrollable to control panels,UC/AC relay receivers and JA-80L sirens

Wireless Gas Leak Detector

JA-80G Wireless Gas Leak Detector

The JA-80G detects mixtures of air and combustible gases or fumes (Natural Gas, Methane, Propane, Butane). The detector detects two levels of gas concentration, responding with two different reactions. The mains-powered detector indicates a gas leakage optically, and acoustically, and transmits alarm wirelessly via Oasis protocol.

JA-180G Langaton kaasuilmaisin

Kaasuilmaisin JA-180G reagoi palaviin kaasuihin ja höyryihin (maakaasu, metaani, propaani, butaani). Aktivoituessaan ilmaisin lähettää keskusyksikköön palohälytyssignaalin ja antaa hälytyksen myös sisäänrakennetulla sireenillä.
