–
The Pre-signal timer is user programmable, ranging from 60 to 180 seconds. The default
is 180 seconds.
–
The Pre-signal delay feature can be enabled or disabled for each input device individually.
–
The global Pre-signal zone is activated if the panel has a Pre-signal input active and is in
the "waiting for reset" period.
–
The Pre-signal feature, if enabled, is valid only under Day Mode. The panel can be in
either PAS mode or Pre-signal mode, not both.
–
The Pre-signal feature is valid in a networked system.
Notice!
In case the Pre-signal option is configured, install a pull station next to the FPA‑1000 in order
to activate the alarm manually.
Positive Alarm Sequence (PAS)
The PAS feature is applicable only to automatic fire detection devices that are the Fire type
(analog and 2-wire smoke or heat detectors).
–
PAS is arranged on a per point basis.
–
All system evacuation signals associated with the activated initiating device and any off-
premises signaling activate immediately and automatically when:
–
The alarm signal from an automatic fire detection device is not acknowledged within
15 seconds of annunciation at the system’s operator interface.
–
The system is not manually reset within the programmed PAS investigation time of
the acknowledgment described in (a).
–
When a second automatic fire detector selected for positive alarm sequence actuates
before the system is reset as described in (b); or when any other fire initiating device
reporting to the system or control unit actuates.
–
The PAS timer is system wide; thus only one timer applies for the whole system.
–
The PAS timer is user programmable, ranging from 60 to 180 seconds. The default is
180 seconds.
–
The PAS feature can be enabled or disabled for each input device individually.
–
In addition, the panel provides a global option to enable or disable PAS.
–
The panel can be in either PAS mode or Pre-signal mode, not both.
–
The PAS feature, if enabled, is valid only under Day Mode.
–
The PAS feature is valid in a networked system.
Notice!
For Positive Alarm Sequence details, refer to NFPA 72 and UL 864.

Events
All point and system events are classified by event groups.
Point events are generated as point status changes.
Each type of point event belongs to a group that is based on when the panel displays and
reports the event in a prioritized style. For a list of point events and the event groups to which
they belong, see the following table.
Point Event

Point bypassed
Point trouble
Point unbypassed
