separate adjustment for each direction of speech. A howling or whistling sound may
indicate the volumes levels are set to high.
Testing / Connecting
The major components of the Digibell system are fitted with high quality pluggable screw
terminal blocks. This enables all the connections to the system to be fully completed, whilst
easily isolating individual pieces of equipment during testing and commissioning.
Any problems can be resolved by rechecking wiring and connections, assisted by the various
suggestions and tests in the section ‘Troubleshooting’.
Connect up one entrance first, leaving any connection to Isolators or phones unplugged:
1. When powered up for the first time, it is recommended that only the most basic system
is connected, i.e. 4/8 phones, 1 BSD-DIG Door controller and entrance panel, 1 DBA-
xx Isolator, the remaining equipment can be isolated by removing terminal blocks.
2. Check the display and buttons on the entrance panel work as expected.
3. If there is an exit button check the door will unlock.
4. Proceed to test the system by calling each phone from the entrance panel in the
normal way, check any available phone features such as buzzer mute or door status.
Once the basic system is fully functioning, continue to connect and test equipment
item by item until completed.
