open)
• Door Station input = Call Button Normally Open (used to detect external doorbell
switch)

Sensor Normally Open, Manual Door Release, Door Control Lockout, Call Button

Testing the door control feature: the “unlock” light on the 8028 will turn on (and the
mechanical relay may be heard) when the Open Code is pressed from the telephone
keypad during a call with the 8028. This light shows the state of the relay, and verifies that
it has activated. If the “unlock” light activates, but the door fails to unlock, please contact
your electrician to check the connections and wiring to the door strike. If the “unlock” light
does not turn on, verify that the phone sends a DTMF signal to the Doorphone.
