Alarm storage circuit for intruder detection system
摘要
The alarm storage circuit (10) has a resistance (6) and a series optocoupler (8) connected in parallel with each opening alarm contact (2), connected in series with the primary line (9) of the intruder detection system. The storage cicuit contains a LED display (11), for providing an optical signal in response to the output signal from the optocoupler upon opening of the alarm contact. A single alarm storage circuit may be associated with a number of opening alarm contacts.
