Panel Control Buttons Operating Instructions
MRP-2001 & MRP-2001E PN 53040:A 4/16/2007 85
SECTION 4 Operating Instructions
Factory programmed Templates have been provided to facilitate the installation and configuration
of the Fire Alarm Control Panel. The factory default programming for this panel is Template #7.
Refer to "FACP Configuration Templates" on page 108 for a detailed description of the FACP
operation for Template #7.
4.1 Panel Control Buttons
4.1.1 Acknowledge/Step
The first press of the Acknowledge/Step key silences the piezo sounder, changes flashing LEDs to
steady and also changes the status field on the LCD display from capital letters to small letters
(TROUBL to troubl). When the piezo is silenced, an acknowledge message is sent to the printer and
the history file. Acknowledge also sends a silence piezo command to the optional annunciators
connected to the FACP. The Acknowledge key will have no effect on the Notification Appliance
Circuits.
When more than one event exists, the first press of the Acknowledge/Step key functions as
described in the preceding paragraph. Subsequent pressing of the key steps through each active
event.
4.1.2 Alarm Silenced
The Alarm Silenced key performs the same functions as Acknowledge/Step, except it will not step
through each event when multiple events are present at the panel. In addition, if an alarm exists, it
turns off all silenceable NACs (Notification Appliance Circuits) and causes the Alarm Silenced
indicator to turn on. It also sends an ‘alarm silenced’ message to the printer, history file and
optional annunciators. A subsequent new alarm will resound the system NACs. The Alarm
Silenced indicator is turned off by pressing the Reset key, the Drill key or subsequent activation of
the NACs.
Note:
1. If Silence Inhibit has been enabled, NACs cannot be silenced for one minute following
initiation of an alarm.
2. When the system is configured for dual hazard operation, an alarm in one hazard area may
reactivate notification appliance circuits programmed for that area only
.
4.1.3 Drill/Hold 2 Sec
When the Drill key is held for a minimum of two seconds (time required to prevent accidental
activations), the FACP turns on all NAC outputs and turns off the Alarm Silenced indicator if it was
previously on. The EVAC IN SYSTEM message is shown on the LCD display. The same message
is sent to the printer and history file. The Alarm Silence key can be used to turn off all silenceable
NAC outputs following activation by the Drill key.
4.1.4 Reset
Pressing and releasing the Reset key turns off all NACs, temporarily turns off resettable power to 4-
wire detectors, causes a RESET IN SYSTEM message to be displayed on the LCD and sends the
same message to the printer and history file. It also performs a lamp test by turning on all LEDs,
piezo sounder and LCD display segments after the Reset key is released. Any alarm or trouble that
exists after a reset will resound the system.
Note that if Silence Inhibit has been enabled, the FACP cannot be reset for one minute following
initiation of an alarm.
