CABLE SIZE GUIDE
Connections for power supply output to intercom panel and lock release connections.
0.5mm²
Connections
The power supply should be located as close to the intercom panel as possible for best performance.
Maximum acceptable resistance for above cables = 3Ω
INSTALLATION
-
Check that all components are free from damage before installing (Do not proceed with
installation in the event of damage).
-
Keep all packaging away from children.
-
Do not obstruct the ventilation openings or slots on any of the devices.
-
All connections to mains voltages must be made to the current national standards (IEE
Wiring regulations)
-
Install an appropriate fused spur or isolation switch to isolate the mains.
-
Isolate the mains before carrying out any maintenance work on the system.
-
Avoid water ingress into the rear of the module, always seal the module frame after
installation using a suitable silicon based sealant.
-
All intercom and access control cables must be routed separately from the mains.
Lock release back EMF protection : A capacitor must be fitted across the terminals on
an AC lock release and a diode must be fitted across the terminals on a DC lock release
as shown in the diagrams below to suppress back EMF voltages.

PANEL CARE
The door panels facia is either mirror finish stainless steel or matt finish aluminium. It is
important that the facia is cleaned on regular occasions to prevent dirt build up and
tarnishing of the metal. A general household metal polish can be used but care should be
taken to follow the grain of the metal when polishing and also avoid any polish build up
around the call buttons which may prevent the buttons from operating correctly.

Do you have a question about the Door Intercom System and is the answer not in the manual?
Questions and answers
Door will not open
The Videx Door Intercom System may not open the door due to several possible reasons:
1. Incorrect Relay Code – The relay code (4-8 digits) entered to operate the door or gate might be incorrect.
2. Relay Time Setting – The relay time might be set incorrectly, preventing the door from opening.
3. Engineer Code Issue – If the red light does not illuminate, the engineer’s code may be incorrect, requiring a factory reset.
4. Power Issues – If the system is not powered correctly, it will not function. Ensure all connections are properly made and power is supplied.
5. SIM Card Not Installed – If using a GSM model, the SIM card must be installed and recognized for the system to function.
6. Dial to Open Disabled – If the "dial to open" setting is disabled, calling the intercom will not release the door.
Checking these factors should help diagnose why the door is not opening.
