7800 Series Keypad Installation Guide 5
Wiring the 333 Suppressor
One Model 333 Suppressor is
included with the 7873 keypad. If
the device being controlled by the
relay is connected to the N/O and
C wires, install the suppressor on
the N/O and C wires. If the device is
connected to the N/C and C wires,
install the 333 on N/C and C wires.
Refer to Figure 7.
Door Strike Relay Operation
As soon as the user code sent
from the reader is veried by the
panel, the keypad door strike relay
activates for 5 seconds. During this
time, the access door connected
to Zone 2 must be opened to start
the programmed entry/exit timer
and zone Bypass (Soft-Shunt™) if
programmed and used.
Note: The 5-second door strike is panel programmable when the keypad is used on an
XR100/XR500 or XR150/XR350/XR550 Series panel. Refer to the panel programming
guide as needed.
Zone 2 Door Contact with Bypass (Soft-Shunt)
If the door being released by the 7873 keypad is protected, you can provide a
programmed bypass time by connecting its contact to Zone 2 (White/Red pair) on the
keypad and enabling the Bypass feature. See ZONE 2 BYPASS later in this document.
Door contacts may be N/C or N/O.
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 between 5 and 250 seconds. This REX time is programmable with a
default of 5 seconds. See ZONE 3 REX STRIKE TIME later in this document.
During this time, the user can open the protected door to start the programmed
Bypass 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 the maximum brightness any time the display is
pressed. During an alarm condition, the touchscreen turns 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.
