Special System Timers
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.
4.20 Special System Timers
4.20.1 Silence Inhibit Timer
This option, if selected, prevents the Alarm Silence key from functioning for 60 seconds following
an alarm. A new alarm during the initial 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 Having
Jurisdiction.
4.20.2 Autosilence Timer
If Autosilence is selected, the notification appliances, programmed as silenceable, will
automatically 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 Jurisdiction.
4.20.3 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
Acknowledge/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.
