Locking the Reset Pin
Locking the reset pin disables the control panel (refer to Figure 1.3, Page 7). When the control
panel is disabled, the system ignores the keypads 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 D9412GV3/
D7412GV3 Program Entry Guide (P/N: F01U170807) or the D7212GV3 Program Entry Guide (P/
N: F01U170808).
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.
When the Reset Switch (labeled S1) is closed, the communication module at SDI Address 92
is disabled. While in this mode, remote programming communication is only supported by the
communication module at SDI Address 88.
