158 MS-9600LS Series Manual — P/N 52646:B2 2/12/2010
Operating Instructions Presignal
4.18 Presignal
Presignal option programs an initiating device to delay the activation of NACs and/or control mod-
ules while allowing visual verification by a person. Once a detector or monitor module triggers an
alarm, the onboard piezo sounds immediately, but the NACs are not activated for a user pro-
grammed time duration of up to three minutes. Note that the alarm relay and communicator will
respond to the initial alarm immediately. In addition, Zone 98 will activate. This zone can be pro-
grammed to a control module which may be used to activate a sounder or indicator which the
installer designates as a Presignal indication. Do not assign Zone 98 to a Notification Appliance
Circuit when using this zone to indicate a Pre-signal condition.
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 the programmed time delay, the alarm will be processed imme-
diately, causing activation of the appropriate output zones. The events which occur upon Presignal
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 98 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 user programmed time delay of up to three minutes
• second alarm occurring anytime during the time delay will cause immediate activation of all
associated outputs
Presignal does not affect monitor modules programmed as waterflow, supervisory, process moni-
toring or remote switches. Presignal operation requires the approval of the local Authority Having
Jurisdiction.
4.19 Positive Alarm Sequence
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 acti-
vate 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 condi-
tion.
When a detector triggers an alarm, the onboard piezo sounds immediately, but the NACs are pre-
vented 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 dura-
tion 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 dur-
ing 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
• ACS annunciators (if enabled) will pulse the Zone 97 PAS LED immediately upon PAS
activation. They will sound the local piezo, and pulse the alarm, associated zone and
detector address point LEDs after 15 seconds of an unacknowledged PAS activation. Note
that if the Alarm Silence or Acknowledge/Step button is pressed, the annunciators will be
inhibited from activating for an additional time delay
• outputs (NACs and control modules) of associated zones will be inhibited from activating
for a factory set duration of 15 seconds
