Alarm Verification
Alarm verification is used to reduce the occurrence of nuisance alarm conditions
(transient smoke etc.). Careful consideration should be taken before enabling the
Alarm Verification feature on any device.
Programming the Alarm Verification
feature may delay the reporting of an actual emergency.
Only those devices that
are subject to conditions that require verification should be programmed with this
feature.
Individual devices within the IF 610 system may be programmed as verification
zones. When this feature is enabled, all automatic detectors connected to the device
are subject to the alarm verification cycle.
Any two wire automatic detectors reporting an alarm condition, programmed for
verification will start the pre-set verification timer (see Programming section) and
the event will be recorded in the verification history log. At the expiration of the
Verification Timer (10 seconds), the device is automatically reset for a period of
four seconds and the devices are allowed a stabilization period (30 seconds). After
the device stabilization period, a sixty second monitor cycle begins. If an alarm
condition is detected during any portion of the verification sequence the system will
activate all CBE functions and the alarm condition processed. If no other alarm
conditions are reported during this period the system resumes normal operation.
Alarm Verification
Tally
The panel counts the number of times each initiating device, assigned to verification,
goes through the verification cycleover the past 30 days without producing a general
alarm. If the total exceed the number programmed into the Tally, a trouble is
originated for the detector. This feature assists in locating detectors which are prone
to false alarms.
Positive Alarm
Sequence
The panel can be programmed to utilize Positive Alarm Sequence (PAS) to minimize
the chances of false alarms while the building is occupied. Careful consideration
should be taken before enabling the PAS feature.
Programming PAS feature may
delay the reporting of an actual emergency.
Positive Alarm Sequence is enabled by
turning on the Day/Night operation feature. When in the Day mode, a smoke detector
must be Acknowledged within 15 seconds, and Reset within 90 seconds of the Ack.
to prevent the sounding of the alarm. Day mode is activated by pressing the Day
switch on the operator control panel. The night (normal) mode can be entered either
manually by pressing the Day switch on the OCP while in the Day mode, or
automatically at a programmed time.
Waterflow Zone
Itiating devices can be designated as Water flow zones. Activated by waterflow
switches, there are three types of Waterflow zones.
1. Water, immediate alarm, not silenceable.
2. Water Retard, alarm is generated if the switch remains closed longer
than the programmed delay, not silenceable.
3. Water Retard Silence, same as Water Retard except the alarm is
silenceable.
