Note: The alarm verification cycle works for each zone as follows:
• Only connect smoke detectors to IDCs with the VSMOKE function type. If a device with the function type VSMOKE enters a current-
limited state, the alarm verification cycle begins. The control unit starts a delay timer of 25 seconds. When the timer expires, the zone
containing the activated detector is reset. Following the reset, another 15 second timer starts. When the 15 second timer expires,
the system checks the zone for an alarm. If a current-limited condition exists on the zone, the control unit initiates a fire alarm. If
no current-limited condition exists, the control unit starts a 2 minute timer. While the timer is counting down, any current-limited
condition on any zone will trigger a fire alarm.
• Only connect the following detectors to IDCs with the VSMOKE function type:
- smoke detectors without an alarm verification feature
- smoke detectors with an alarm verification feature of less than 10 sec that do not reset
A short from a pull-station always triggers an alarm condition, regardless of the alarm verification cycle.
At any stage of the alarm verification cycle, the presence of two devices in alarm triggers an alarm condition.
