44 Pelco Manual C690M-E (11/04)
Remember the following when programming alarms:
• When two alarms are activated, the last alarm to turn on is the one that will be recorded.
The system is designed to begin recording the second alarm and stop recording the first
alarm even before the first alarm’s duration time expires. There is a reason for this.
For example, after a break-in occurs at the front door of an office, there is no more need to
record that door. Instead, the system’s resources are concentrated on the next area the
person enters. In effect, the system follows someone through the building via alarms.
However, if the customer wants, he can program more than one camera to record and still
get coverage in multiple areas.
• Momentary-triggered contacts turn on only when they go from off to on. Latch-triggered
contacts and all other events continuously turn on so long as their triggers are active.
(Momentary and latch are further defined in step 5 that follows.)
For example, if two latch alarms are activated, then the second takes priority. However, if
you have motion or latch alarms active and a momentary alarm is activated, then the
momentary alarm will be ignored.
