6 7800 Series Keypad Installation Guide
PRELIMINARY
Zone 2 Door Contact with Soft-Shunt™
If the door being released by the 7873 keypad is protected, you can provide a
programmed shunt time by connecting its contact to Zone 2 (White/Red pair) on
the keypad and enabling the Soft-Shunt feature. See ZONE 2 SHUNT later in this
document. Door contacts may be N/C or N/O.
Note: The Door Strike time is programmable when the keypad is used on an XR100/
XR500 Series panel.
Zone 3 Request to Exit
You can also connect a N/O PIR (or other motion sensing device) or a mechanical
switch to Zone 3 (White/Orange pair) on the 7873 keypad to provide request to exit
capability. See ZONE 3 EXIT later in this document. When Zone 3 shorts, the keypad
relay activates for 5 seconds. During this time, the user can open the protected door
to start the programmed Soft-Shunt entry/exit timer. If the door is not opened within
5 seconds, the relay restores to its locked state.
Note: A Zone 3 Request to Exit is inhibited for 3 seconds after the keypad reads a card
and a door strike occurs. This is to allow area entry and pass under a REX PIR.
Keypad Backlighting
The touchscreen illuminates at full brightness any time the display is touched. When
the speaker is sounding, the backlight illuminates at one-half (1/2) brightness. During
an alarm condition, the keyboard and logo turn Red. When all alarm conditions are
cleared from the display, the keyboard, logo, and the user-selected brightness is
restored.
AC Power/Armed LED Operation
The LED indicates the Power and Armed status of the panel. Depending on the
operation, the LED displays in Red or Blue as listed in the table.
