Group Type Description
NFPA 72 National Fire Alarm Code requires the following for Counting Zone:
1) There shall be at least two automatic detectors in each protected space.
2) The alarm verification feature shall not be used.
3) The detectors shall be installed at spacing determined in NFPA 72, when
used to initiate fire safety functions or fire extinguishing systems.
4) The detectors shall be installed at a linear spacing not more than 0.7 times
the linear spacing determined in NFPA 72, when used to activate public
mode notification.
PAS Positive Alarm Sequence group as defined by NFPA. The alarm signal from a device
selected for positive alarm sequence operation will activate selected output zones of
the PAS Group. The signal shall be acknowledged within 15 seconds in order to
initiate the alarm investigation phase. If the signal is not acknowledged within 15
seconds then selected output zones of the associated Timeout Group will activate.
The Timeout Group must be a Fire Group that activates an audible NAC.
The investigation phase (Timer) can be programmed from 60 to 180 seconds. If the
system is not reset during this period, the Timeout Group will activate.
If a second PAS alarm occurs during the investigation phase, the selected output
zones of the associated Timeout Group will activate.
If PAS is disabled, then the initial alarm signal will activate the selected output zones
of the PAS Group and the output zones of the associated Timeout Group.
Pre-Signal Pre-signal as defined by NFPA allows initial Fire Alarm signals to sound only in
department offices, control rooms, fire brigade stations or other constantly attended
central locations for which human action is subsequently required to activate general
alarm or a feature that allows the control equipment to delay the general alarm by
more than 1 minute after the start of alarm processing. If there is a connection to a
remote location, the transmission of the alarm signal to the supervising station shall
activate upon the initial alarm signal.
On the initial alarm, the selected output zones associated with the pre-signal group will
activate. The delay of activation of additional output zones can be programmed from 60
to 180 seconds. If the system is not reset during this period, the output zones of the
associated Timeout Group will activate. The Timeout Group must be a Fire Group.
Wild Card
Wild Card zone for non-fire operation allows monitoring of critical functions with logging
or control function. The event will latch and will not reset until the panel is reset.
Releasing
Group
This group type is the only input group that can activate the releasing circuit. When
this type is selected, the following parameters have to be configured:
- Releasing Group Threshold setting: This sets the threshold to initiate a
Pre-Discharge condition and can be selected from the following: Any 1
alarm, Any 2 alarms, Any 1 smoke detector and Any 1 thermal device.
- Releasing Circuit Activation: This selects the releasing circuit that will
activate when this Group is initiated.
- Releasing Circuit Code Selection: This screen allows the user to select
the type of pre-defined signal for the releasing NAC type to play if the
condition has been met. 1
st
Alarm, Discharge and Pre-discharge are
defaulted to activate Steady ON.
-
Output Zone:
This sets the output zones that the releasing group activates.
NOTE: Any alarm condition that is initiated from the releasing input group will
generate a general alarm condition.
Notes:
1. Zone Coding signals are not allowed to be associated with the Releasing Input Group.
2. When the Releasing Input Group utilizes the predefined signal codes on its releasing NAC
outputs, all other Input Group type NAC outputs must be set to Steady On only.
3. Releasing should be enabled before selecting a releasing group.
4. 8701, 8702, 8703 and 8704 devices assigned to “Drill,” “Alert” or “Recall” system groups should
have their usage set to supervisory.
