Gas detection device GS 2.1, (propane/butan) 61187

Gas warning device GS 2.1 for private houses, with integrated sensor, alarm buzzer and relay output for connecting additional alarms such as external buzzers or lamps. Principle and operation like GS 1.1.
The device is equipped with an input for connecting external gas sensors type GS 4.1 as 2nd measuring point. It is thus possible to monitor two endangered but separate zones. Operating status and alarm are indicated separately for both zones. The acoustic signal will however only be
activated at the central device GS 2.1 and can only be stopped by the reset key. The acoustic signal remains active as long as the alarm situation
cannot be removed.
The gas sensor GS 4.1 is a remote sensor for the gas warning device GS 2.1. The semiconductor sensor is built into the housing. The LEDs are for GS 1.1 and GS 2.1. The alarm status is stored in GS 2.1. The life expectancy for the semiconductor sensor in GS 1.1/GS 2.1/ GS 4.1 is approx. 5 years
depending on the operating conditions.
