TESTING THE DOOR PHONE
You are now ready to test the DOOR PHONE connection by pressing the Call Button
on the Door Phone.
Your PBX or other Multi-Line telephone system should now connect the DOOR
PHONE call to the correct destination. Have someone answer the call to
communicate.
Note - The Destination telephone must be located at least 10ft from the Door
Phone, or you may only have communication in 1 direction. If you are using a
Cordless Phone or Cell Phone, you may need to walk away until communication in
both directions is achieved.
Once you hang up, DS4 should disconnect the call after detection of 3 ‘Hang Up
tones’.
If the AUDIO Connection is not clear in both directions, you will need to adjust the
Balance Pot, as described on page 13.
TROUBLE SHOOTING
If your Phone System does not respond when you have pressed the Call Button on
the Door Phone, then you should:
•
Open the supplied Interface Unit and temporarily short across the internal screw
terminals connected to the RED and GREEN wires.
•
If the Phone System does not respond, it may not be programmed correctly.
•
You should remove DS4 from the ANALOGUE extension and connect an
ANALOGUE telephone or test phone in its place. You should only fit DS4 back on
the ANALOGUE extension once an ‘off hook’ by your ANALOGUE telephone or test
phone causes your telephone system to respond correctly.
•
If the Phone System responds correctly, then there may be a problem with the
cabling from the Door Phone to the interface unit. You should temporarily short
across the center 2 positions of the 4 position Phoenix plug which connects to the
Door Phone (or the 2 screw terminals if you are using a DP1). If the Phone system
does not respond, then you have a problem with the cabling back to the DS4 that
must be repaired or replaced. If the Phone system does respond, then you may have
a problem with the Door Phone. Call 07 5596 5128 for assistance.
