Table 7-1 list the delay choices and a description of each.
4. Press ENTER .
Table 7-1: Alarm Delay Types
Type of Delay Description
1-Count One Count (No Delay). When this option is enabled, an alarm occurs immediately when a
single device of any of the following types goes into alarm: detector, manual pull, water
flow, Aux1 or Aux2. This is considered the most typical operation and is the default for all
zones.
2-Count When this type of alarm delay is used, two or more detectors within the zone must go into
alarm in order for the zone to report an alarm. Switches of type manual pull, water flow,
Aux1 and Aux2 are an exception; they will cause an alarm when only one switch is in
alarm.
When a single detector is in alarm in a 2-Count zone, the system enters a prealarm
condition. In a prealarm condition, the touchpad PZT beeps and the annunciator display
indicates that a prealarm has occurred. If the zone has been mapped to an output group
for the prealarm event, the output group will activate. The prealarm will not be reported to
the central station.
Alarm Ver. Alarm verification is an optional false alarm prevention feature that verifies an alarm
condition by resetting the smoke detector. If the alarm condition still exists by the time the
reset cycle has completed, the detector will go into alarm. If the detector is no longer in
alarm, no report will go to the central station. The alarm verification sequence is ignored if
the zone is already in alarm.
PAS This option is intended to be used with an acknowledge switch. An alarm is delayed for
15 seconds, giving on-site personnel a chance to investigate the alarm. If the
acknowledge switch is not activated within 15 seconds, an alarm occurs automatically.
If this option is enabled for a zone, the zone will respond to an alarm condition as follows:
• The zone will not go into alarm for 15 seconds to allow an on-site operator to activate
the acknowledge switch.
• If the operator does not press the acknowledge switch within 15 seconds, the zone
will go into alarm.
• If the operator presses the acknowledge switch within 15 seconds, a 180-second
time-frame will begin counting down. This time-frame allows the operator to investi-
gate the cause of the alarm.
If the operator performs a reset within 180 seconds, the alarm will not occur.
If the operator does not perform a reset within 180 seconds, an alarm will occur
automatically.
• The P.A.S. feature will be overridden if another alarm occurs.
SNGL ILOCK See Section 8.6.1 for single interlock releasing operation.
DBL ILOCK See Section for double interlock releasing operation.
Note: SK-Fire-CO and other CO detectors can only be installed in a 1 count zone; they will operate as a 1
count point regardless of the programmed zone type (i.e. Alarm Verification, 2 count, etc.).
