3.9.3 General Alarm Relay Output
Pins 6, 7 and 8 contain a Form C single pole changeover contact set. The general alarm relay
(GAR) will activate (i.e. the normally open pole will close) if any of the following valid alarms are
triggered on any channel of the Presidium:
• video motion detection
• contrast
• no video
• external alarm input
• tamper
The GAR contacts will remain in the changeover condition until all alarms are reset, with the
following conditions:
• When an alarm output is set to ‘pulse’, the GAR will remain active for the duration of the
longest pulse time of any alarm input source that has been activated.
• When an alarm output is set to ‘while active’, the GAR will remain active while any alarm
input source is active.
• When a combination of ‘pulse’ and ‘while active’ is used by various inputs, the GAR will
remain active for the longest pulse time (of teh various sources that have become active),
or,.while any source (not set to a pulse time) is active.
• When set to ‘pulse’, the GAR will not re-activate until the longest alarm hold-off period (for
any channel that has gone into alarm) has expired.
Refer to Specifications on page 89 for the relay specifications.
