Door Strike Relay Operation
As soon as the user code sent from the reader
is verified by the panel, the keypad door strike
relay activates for five 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 five–second door strike is panel
programmable when the keypad is used on an
XR150/XR550 Series panel. Refer to the panel
Programming Guide (LT-1232) 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 on page 19 for more
information. Door contacts may be N/C or N/O.
