Troubleshooting
We have identified a number of issues that may occur during or after installation that may reduce the
quality of the ACTentry A10 operation. If you do not feel your system is working at an optimum level
please review the following prior to contacting our Technical Support Helpdesk.
Low Volume through the Speaker Grill on the Door Entry Panel
Please check the following:
1. Adjust the Volume from the Speech Unit by adjusting controlA.
2. Ensure that the Speaker Grill is fitted securely against the Door Entry Panel Grill.
3. Check the Door Entry Panel Grill for any blockages
4. Check that the supply voltage is at an adequate level. For best operation it should be
between 10V and 15V between terminals marked C and H on the speech unit.
When in use a constant tone/feedback (howl or whistle) is experienced from the Speech Unit
1. Volume adjustment may be required on the Speech Unit contained in the Door Entry Panel.
Turn both A and B controls “off”. Turn back on and slowly adjust each control in turn until
the optimum volume has been achieved.
2. Ensure that the Speaker Grill unit is fitted securely against the Door Entry Panel Grill.
3. The “O” connection from Speech Unit and the Door Intercom Handset is disconnected.
This will dramatically reduce the feedback threshold. Check your wiring for this fault.
4. The Door Entry Panel and the Door Intercom Handset are too close together. You
should not be able to hear the caller without the use of the Door Intercom Handset.
5. The Door Entry Panel is surrounded by reflecting walls e.g. a basement flat. In this situation
acoustic feedback may occur at lower volume levels. It may be necessary to change the
position or orientation of the panel.
6. Check the Door Entry Panel Grill for any blockages
The Caller cannot be heard through the Door Intercom Handset
1. This could indicate a wiring fault on the speech signal connections R or T.
• R carries the audio from the Door Intercom Handset to the Door Entry Panel.
• T carries audio from the Door Entry Panel to the Door Intercom Handset.
The Door Intercom Handset will not buzz
1. This could indicate a faulty “O” or “I” line between the power supply and the Door
Intercom Handset.
• To test this check for a reading of between 10.5V – 15V between I and O when called.
The Door Intercom Handset ‘DOOR’ button does not operate release
1. Check for a fault on the Z or O line
2. Check that there is not a missing connection to theACTentry A10 PUSH BUTTON terminal.
