System overview and operation
1.4 FireShield Technical Reference Manual
Operating the panel
Resetting the panel
Pressing Reset places the panel in the reset state. The panel
should not be reset until the appropriate authority has
determined that the hazard is no longer present.
When you reset the panel:
• All LEDs on the panel light for five seconds
• The trouble and power lights remain on for an additional
15 seconds
• When reset is complete, the buzzer sounds (then turns off)
and the trouble LED turns off
In this state:
• All panel indicators are temporarily cleared
• All notification appliances are turned off
• All latched IDCs are cleared
• Alarm, trouble, and supervisory relays are returned to the
inactive state
• Auxiliary power (if programmed as resettable)
momentarily turns off
At the conclusion of the reset, if an IDC is in an off-normal
state, the panel treats the event as a new event and activates
the programmed responses. Pressing Disable for the active
IDC within 30 seconds after the panel has reset turns off the
NACs and disables the IDC.
If one or more IDCs are disabled prior to initiation of the reset,
those IDCs remain disabled.
If signal silence inhibit or reset inhibit is enabled, system reset
is inhibited during the silence or reset inhibit period.
To reset the panel:
1. Press the Reset button.
Silencing panel and FSRSI buzzers
Both the panel and the optional FSRSI module have buzzer
silence buttons. Pressing the Panel Silence button silences the
buzzer on the panel and on remote FSRSIs.
Pressing the FSRSI Silence button silences the buzzer on the
FSRSI only.
To silence the panel buzzer:
1. Press the Panel Silence button on the panel.
2. Determine the type of condition that caused the buzzer to
sound: alarm, trouble, supervisory, or monitor.
3. Determine the cause of the condition.
To silence an FSRSI buzzer:
1. Press the Silence button on the FSRSI.
2. Determine the type of condition that caused the buzzer to
sound: alarm, trouble, supervisory, or monitor.
3. Determine the cause of the condition.
Silencing notification appliances
Pressing the Signal Silence & Drill button turns off all audible
devices. Visual devices or NAC circuits may or may not turn
off, depending on panel programming.
When you silence the signals, the Signal Silenced LED lights,
indicating that the notification appliances are off. The panel
does not indicate a trouble condition. If GENESIS,
horn/strobe, or horn-only devices are used on NACs
programmed for GENESIS operation, Signal Silence & Drill
silences only the horns.
WARNING: The notification appliances should not be silenced
until the building is fully evacuated and the cause of the alarm
has been determined.
To silence notification appliances:
1. Press the Signal Silence & Drill button.
When the auto signal silence timer is programmed
When an event activates the notification appliances, the 20-
minute auto signal silence timer is activated. The notification
appliances are activated for the 20-minute period. When the
timer expires, any NACs that are programmed as silenceable
are deactivated, and the Signal Silenced LED is illuminated.
If another event takes place that activates the previously
silenced notification appliances, the Signal Silenced LED
turns off. At any time, you can deactivate silenceable NACs
by pressing Signal Silence & Drill.
Note: NACs activated by IDCs programmed as waterflow
cannot be silenced until the activated devices are restored to
normal. After the devices restore, the Signal Silence & Drill
button or the auto signal silence timer can silence the NACs.
Resounding an alarm condition
Pressing the Signal Silence & Drill button again turns the
audible devices back on if they were silenced.
To resound notification appliances:
1. Press the Signal Silence & Drill button.
Note: NACs resound automatically if a new alarm (from
another IDC) is received.
