Gas Alarm GA 90: This gas warning device alerts early to escaping town or natural gas (methane) or liquefied gas (propane/butane). The highly sensitive semiconductor sensor is factory calibrated to report gas concentrations well below the lower explosion limit. Functionality: The gas detectors GA90 and CO90 can be used independently and warn through a built-in siren. The integrated relay contact allows for connection to an alarm control panel, control of a valve, or a ventilation system. An additional 12-volt alarm output can be connected to an external siren for external alerting.
