Alarm Delay Characteristics
The programmed zone type is provided for user reference only. To modify the zone type use the SKSS-2 Silent
Knight Software Suite
Table 9-1 list the detector characteristics and a description of each.
Type of Delay
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, Zone Aux1 or Zone 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, Zone Aux1 and Zone 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.
When two count is used detector spacing shall be cut in half, you shall not use the alarm verification
feature, and no delay shall be used.
IDP-Fire-CO detectors can be installed in a 1 or 2 count zone but will operate as a 1-count point in that
zone.
Alarm Verification 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.
P.A.S.- Positive Alarm This option is intended to be used with an acknowledge switch. An alarm is delayed for 15 seconds, giving
Sequence 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
• 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
• The P.A.S. feature will be overridden if another alarm occurs.
Single Interlock See Section 10.7.1 for single interlock releasing operation.
Double Interlock See Section 10.7.2 for double interlock releasing operation.
Heat Detector Sensitivity
Use this feature to set the temperature at which high temperature detectors will respond.All detectors in the zone
will respond in the same way.The range for IDP-Heat-HT heat detector is from 135°F to 190°F.
The high temperature IDP heat detectors are absolute temperature devices. This means that they respond to an
alarm immediately if the temperature in the zone goes above the programmed temperature.
3. Enter the temperature at which the heat detector will respond, or use the Up or Down arrow to scroll through
the range, or enter directly from the number keys on the annunciator, then press ENTER.

switch.
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 automatically.
