BETA 754/756 Gas leak control unit and remote detector with Replaceable Sensor and optical-acoustic alarm and relay
Remote detector for methane and LPG to be connected to the BETA 756 control unit. It signals the presence of gas in the environment via optical and acoustic alarms and sends a signal to the BETA 754 control unit, which shuts off the gas solenoid valve.
In both methane and LPG versions, the detectors are calibrated to detect a gas concentration equal to 10% of the LEL (Lower Explosive Limit). This threshold may vary depending on environmental conditions but will in any case not exceed 20% of the LEL during the first 5 years of operation. These thresholds are guaranteed for a maximum period of 5 years.
At the end of this period, an optical signal indicates the need to replace the sensor, an operation that can be easily performed by removing a cover and using the replacement sensors supplied in blister packs.
