And Initiating
Circuit
This circuit is a two-stage automatic detection zone that will operate as an
Automatic Alarm Initiating Circuit for the first two-wire smoke detector alarm
reported to the panel. Should another two wire smoke detector go into alarm on
the same AND circuit, a second alarm output will occur. This circuit is useful
for a simple cross zone of two detectors. An example of typical application
would be in an elevator lobby, where elevator capture doesn't occur until both
detectors have alarmed. However, other normal alarm responses occur when the
first detector activates. A short on the circuit will initiate a second stage alarm
immediately.
