Locking the Reset Pin

Locking the reset pin disables the control panel
(Figure 4). When the control panel is disabled,
the system ignores most keypad commands and
points. CALL FOR SERVICE appears in keypad
displays when the pin is locked down.
On-board relays (Terminals 6 and 7) and off-
board relays deactivate when the control panel is
reset. Terminal 8 has power when the relay is
deactivated. Activation interrupts power at that
terminal. The on-board relay (Terminal 8) remains
deactivated when the reset pin is locked in the
disable position.
Releasing the reset pin from the closed position
resets the control panel. The control panel resets
all its timers, counters, indexes, and buffers. Any
points that restore after a reset do not generate
Restoral Reports.
If the reset pin is placed in the disable position
when all areas are armed, there must be an entry
in the Answer Armed program item. Refer to RPS
Parameters in the
D9412GV4/D7412GV4/D7212GV4 Program Entry
Guide (P/N: F01U218312).
Locking the pin in the disable position applies
power to the control panel and charges the
battery while the detection devices and keypads
are installed.

in the closed position.
4.6.1

Charging the Battery

Connect the battery, then the transformer to
allow the control panel to charge the battery
while you complete the installation. Refer to
Section 5.0 Power Supply on page 24 for
instructions.
On-board Buzzer Sounds at Power Up and Reset:
The system performs a series of self-diagnostic
tests of hardware, software, and programming at
power up and at reset. The buzzer on the control
panel sounds during the tests. The self-
diagnostics tests complete in approximately 1 to
3 sec.
If the control panel fails any test, the buzzer
continues sounding and a System Trouble
message appears at the keypads.
Touch Terminal 10 First: If the on-board buzzer
sounds briefly when the control panel is touched,
any static charge you carry discharges to the
control panel.
Avoid electrostatic discharge. Always
touch Terminal 10, the earth ground
connection, before beginning work on
the control panel.
If the control panel receives an electrostatic
discharge, it might generate Watchdog Reset and
Param Fail events.
