Special System Timers; 1: Silence Inhibit Timer; 2: Autosilence Timer; 3: Trouble Reminder - Fire-Lite MS-9600LS Manual

Operating Instructions
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
• 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
• 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.

4.21 Special System Timers

4.21.1 Silence Inhibit Timer
This option, if selected, prevents the Alarm Silence and Reset keys from functioning for 60 seconds
following an alarm. A second alarm during this 60 second period will not cause the timer to restart
with a new 60 seconds. Silence Inhibit operation requires the approval of the local Authority Hav-
ing Jurisdiction.
4.21.2 Autosilence Timer
If Autosilence is selected, the notification appliances, programmed as silenceable, will automati-
cally be silenced after a programmable duration of from 5 to 30 minutes. Pressing the Drill key will
restart the timer. Autosilence operation requires the approval of the local Authority Having Juris-
diction.
4.21.3 Trouble Reminder
If selected, this feature causes a reminding 'beep' every 15 seconds during an alarm (after the
Alarm Silence key is pressed) and every two minutes during a trouble condition (after the Acknowl-
edge/Step or Alarm Silence key is pressed). The 'beeps' from the onboard piezo sounder will occur
until the alarm or fault is cleared.
Note that if the trouble is not cleared within 24 hours, the piezo will resound, indicating that the
trouble condition still exists.
