Alarm Delay Characteristics

3. Select the alarm delay characteristics (see Table 7-1) by pressing the
Type of Delay
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
1-Count
considered the most typical operation and is the default for all zones.
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.
2-Count
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 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.
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 acknowl-
edge switch.
• If the operator does not press the acknowledge switch within 15 seconds, the zone will go into
PAS
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 automatically.
• The P.A.S. feature will be overridden if another alarm occurs.
See Section 8.7.1 for single interlock releasing operation.

Heat Temperature Setting

Use this feature to set the temperature at which heat detectors will respond. The range is 135°
to 150° F. All detectors in the zone will respond in the same way.
The Model SD505-AHS Heat Detector is an absolute temperature device. This means that it
responds to an alarm immediately if the temperature in the zone goes above the programmed
temperature.
5. Enter the temperature at which the heat detector will respond.
