NOTE:
For DC-powered electric strikes, connect the included diode as close as possible and in parallel with
the electric strike. This absorbs possible electromagnetic interference to prevent operation of the
strike from damaging the keypad. Do not connect a diode when using electromagnetic locks or with
AC powered strikes.
Programming the Interlock System:
When programming the interlock system, use the following general formula from within base
programming mode (see "Enter and Exit Base Programming Mode," pg. 9):
– Program the Interlock System function code (LED will change to steady orange)
– Disable or Enable the Interlock System
Disable or Enable the Interlock:
– Disable the interlock (factory default)
– Enable the interlock
NOTE:
The key returns you to base programming mode (the LED will flash red). Exit programming
mode by pressing the key (see "Enter and Exit Base Programming Mode," pg. 7).
