The GMYA7-AS remote test system consists of a key module and a single indicator module. It enables daily routine function tests to be conducted on up to 8 seismic detectors independent of an intruder alarm system. The GMYA-AS can only be used with the seismic detector GM775 and in combination with the GMXS1. The identification of alarms and test function independent of an alarm panel is mainly required and used for VdS approved seismic detector systems.
