Positive Alarm Sequence

4.19 Positive Alarm Sequence
MS-9200UDLS PN 52750:A 11/04/05
PAS (Positive Alarm Sequence) option will program a smoke detector to delay panel
activation (including alarm relay and communicator) for a period of 15 seconds. Zone
97, however, will activate immediately and may be used to connect a signaling device
to indicate PAS activation. Do not assign Zone 97 to a Notification Appliance Circuit
when using this zone to indicate a PAS condition.
When a detector triggers an alarm, the onboard piezo sounds immediately, but the
NACs are prevented from activating for 15 seconds. This inhibit time is factory set and
cannot be changed. Pressing the Alarm Silence or Acknowledge/Step key during the 15
second inhibit time will silence the piezo sounder and start a timer which prevents
activation of NACs for an additional time duration which can be user programmed for
up to three minutes. After the programmed delay, the NACs will activate if the source
of the alarm is not cleared. Note that if a second alarm occurs during either time delay,
the alarm will be processed immediately, causing activation of the appropriate output
zones. The events which occur upon PAS activation are as follows:
onboard piezo sounds immediately
control panel LCD display will indicate a presignal event and the active point
control points programmed to Zone 97 will activate
annunciators (if enabled) will sound the local piezo, and pulse the alarm LED
and zone LED
outputs (NACs and control modules) of associated zones will be inhibited
from activating for a factory set duration of 15 seconds
pressing the Alarm Silence or Acknowledge/Step key will start a timer which
inhibits output activation for additional time delay of up to three minutes
which is user programmable
second alarm occurring anytime during either time delay will cause immediate
activation of all associated outputs
PAS operation requires the approval of the local Authority Having Jurisdiction.
Note that the PAS BYPASS monitor type code, when activated, will inhibit the PAS
capability until the PAS BYPASS monitor is deactivated. While PAS is inhibited,
signaling devices will immediately place the control panel into alarm. This feature may
be employed by wiring a normally open device, such as a switch, to a monitor module
which has been programmed for PAS BYPASS.
