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 investigate 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 automati-

cally.

• The P.A.S. feature will be overridden if another alarm occurs.

SNGL ILOCK See Section 8.5.1 for single interlock releasing operation.

DBL ILOCK See Section for double interlock releasing operation.
