2.5.5Locking the Reset Pin
Locking the reset pin disables the control panel. When the reset pin is locked, the control panel is disabled. CALL FOR SERVICE appears in some keypad displays (SDI2 keypads display enter Installer Passcode) when the pin is locked down.
Unlocking the reset pin from the locked 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 Lock position, and all areas are armed, the control panel will not answer RPS over a phone line unless the Answer Armed program item has a value other than zero in it. No entry is required for network or RPS Enhanced direct connection communication. Refer to RPS Parameters in RPS Help.
