Activate Strike Relay and Bypass
Wire zone 3 as normally open with a 1K Ohm EOL resistor.
When zone 3 shorts, the onboard Form C relay activates for
the programmed number of seconds. See Zone 3 REX Strike
Time. During this time, the user can open the protected door
to start the programmed zone 2 bypass entry/exit timer. After
the programmed number of seconds, the relay restores the
door to its locked state.
Activate Bypass Only
Wire zone 3 as normally closed with an in-line 1K Ohm resistor.
When zone 3 opens from a normal state, only a bypass occurs:
the onboard relay does not activate.
