Door Strike Relay Operation
When 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 if
programmed and used. The five second door strike is panel programmable when the
keypad is used on an XR150/XR550 Series panel.
Zone 2 Door Contact with Bypass
If the door being released by the 7073/A and 7173 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. 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 7073/A and 7173 keypad to provide Request to Exit
(REX) capability. 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 Bypass entry/exit
timer. If the door is not opened within five seconds, the relay restores to its locked state. A
Zone 3 REX is inhibited for three seconds after the keypad reads a card and a door strike
occurs. This is to allow area entry and pass under a REX PIR.
