Operation and Controls Information

Door Ajar Function

Default Condition —After the door has been opened by the four digit code or the remote push button, the Door Phone Controller will wait for the Door Ajar Call-back time-out to elapse. At this point if the door is still open, the Door Phone Controller will call back the phone/chime for the duration of the ring/chime duration and then repeat after the Door Ajar Call-back time-out has elapsed again. If the phone is answered during that time, a Door Ajar Tone will be heard. The Door Ajar Tone will cease when any DTMF Digit is pressed, or the user speaks or hangs-up.

Alternate Condition —If the door is ever opened and the Door Ajar Call-back time-out has elapsed, the Door Phone Controller will call back the phone/chime for the duration of the ring/chime duration and then repeat after the Door Ajar Call-back time-out has elapsed again. If the phone is answered during that time, a Door Ajar Tone will be heard. The Door Ajar Tone will cease when any DTMF digit is pressed, or the user speaks or hangs-up.
