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.
Any two wire automatic detector 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.
