4.11 4.11 4.11 4.11 4.11 Presignal Presignal Presignal Presignal Presignal
Presignal is used to delay output activation (control modules and NACs) while allowing for visual verification by a
person. Once a detector or monitor module triggers an alarm, the onboard piezo sounds immediately, but the
Notification Appliance (bell) Circuits are not activated for 15 seconds. During this time, if the acknowledge switch
is pressed, the piezo is silenced and the Notification Appliances will not activate for up to 3 minutes. After 3
minutes, the Notification Appliances will activate if the source of the alarm is not cleared. This does not affect
monitor modules programmed as waterflow or supervisory. Presignal operation requires the approval of the local
Authority Having Jurisdiction.

This option, if selected, prevents the ALARM SILENCE switch from functioning for 60 seconds after an
alarm. A new alarm during the initial 60 seconds will cause the timer to restart with a new 60 seconds.
Silence Inhibit operation requires the approval of the local Authority Having Jurisdiction.
AUTO SILENCE TIMER (NONE OR 10 MINUTES) AUTO SILENCE TIMER (NONE OR 10 MINUTES) AUTO SILENCE TIMER (NONE OR 10 MINUTES)

If Auto Silence is selected, the Notification Appliances will be silenced automatically after ten minutes of
activation. Pressing DRILL will restart the timer with a new 10 minutes. Auto Silence operation requires
the approval of the local Authority Having Jurisdiction.
TROUBLE REMINDER TROUBLE REMINDER TROUBLE REMINDER

If selected, this feature causes a reminding 'beep' every 15 seconds during an alarm (after the Silence
switch is pressed) and a 'beep' every two minutes during a trouble condition after the Acknowlede or
Silence switch is pressed. The 'beeps' from the onboard piezo will occur until the alarm or fault is cleared.

If alarm verification is selected, an addressable smoke detector's alarm is ignored for a retard time of 13
seconds and the detector's alarm condition is automatically reset. There will be no alarm indication at the
FACP during the Retard period. A confirmation period of 1 minute and 47 seconds follows, during which a
subsequent alarm from the same detector will cause the panel to immediately activate the appropriate
outputs and indicate the alarm condition at the FACP. If a different detector alarms any time during the
first detectors verification period, the panel will immediately activate all appropriate outputs and indicate
the alarm condition at the FACP. If no additional detector alarms occur within 2 minutes of the first alarm
(13 second retard plus 1 minute and 47 second confirmation), the timer resets and the panel is ready to
verify any new detector alarms which may occur.

If an alarm exists from a monitor module point that has a Waterflow type code, the ALARM SILENCE
switch will not function.

Input points which are disabled do not cause an alarm or any CBE (Control-By-Event) activity. Disabled
output points are held in the off state. All disabled points are treated as if they were in trouble except the
status label displayed is DISABL
