  • Alarm system with monitoring circuit for detecting a cut or short in a pair of wires
    Patent number: 5387899
    Abstract: An alarm system is described wherein both an open connection between an alarm monitor and an alarmed unit or a short circuit across the connection between the monitor and the unit can be detected. A controllable, normally open test device is placed in parallel with a normally open alarm contact. If current flows when the test device is open, either a short circuit or an alarm condition exists. If current does not flow when the test device is closed, an open connection between the monitor and the unit exists. Advantageously, the integrity of connections between alarm monitors and alarmed units is enhanced.
