Supervisory Mode
When the panel is in the Supervisory Mode, a portion of the building fire protection system (not the panel)
is in an abnormal condition and its proper operation is affected. If an alarm occurs while in the supervisory
mode, the panel will enter the alarm mode and sound an alarm. If a supervisory condition is detected while
in the trouble mode, the panel enters the supervisory mode.
In the supervisory mode, the system trouble LED, amber supervisory zone LED, and trouble buzzer all
operate at 120 pulses per minute. The trouble relay operates and the Relay/City-Tie Module (if configured
to transmit supervisory alarm) transmits a supervisory and trouble signal. The respective zone LED on the
remote annunciator will illuminate. The dialer will transmit a zone specific supervisory signal to the Central
Monitoring Station.
Restoration of the supervisory condition causes the amber supervisory zone LED to light steadily. The
trouble buzzer continues to pulse rapidly, or will resound if previously silenced. The respective zone LED
on the remote annunciator will remain illuminated during the supervisory restore mode.
Press the RESET switch to exit the supervisory mode when all supervisory alarms have restored. The dialer
will transmit a zone specific restore signal to the Central Monitoring Station.
Drill Mode
The drill mode operates both IACs. The panel will leave the drill mode, enter the alarm mode, and sound
an alarm if an alarm is detected. The panel will leave the drill mode and enter the supervisory mode if a
supervisory condition occurs.
The drill mode is entered from the normal mode by simultaneously pressing the ALARM SILENCE and RESET
switches for at least one second. Entering the drill mode places the panel in the trouble mode. The trouble
LED will flash slowly. Pressing the
ALARM SILENCE switch terminates the drill. The alarm relay and the
Relay/City-Tie Module (when configured to transmit alarms) do not operate in the drill mode.
To exit the drill mode, either press the ALARM SILENCE switch, or press the RESET switch.
IDC Zone Disable
Initiating Device Circuits (IDCs) may be individually Disabled by operating a zone’s
ZONE DISABLE switch.
WARNING
Disabling a zone removes the zone’s ability to put the panel in an Alarm or Supervisory condition.
Disabling a zone permits the panel to be reset and restore protection to all zones except the disabled
ones. The
ZONE DISABLE switch is also used to select a zone for testing, as detailed in the section entitled
Test Mode.
When a zone(s) is disabled, the Zone Disabled LED as well as the individual zone trouble LED exhibit a 2-
phase flash, and the panel is put in the trouble mode. If the panel was in an Alarm, Supervisory, or Trouble
state when the
ZONE DISABLE switch was activated, the panel will not return to normal.
When a disabled zone is re-enabled, its zone LED indicates its status. If a re-enabled zone indicates it is in
alarm, the panel will wait 10 seconds before going into the alarm mode. Pressing the
ZONE DISABLE switch
within the 10 second period disables the zone again, without the panel going into the alarm mode. A
disabled zone's status is retained in the panel's memory during power down, and will remain disabled upon
power up. Panel reset does not change a zone's enabled/disabled status.
