INSTALLATION
The wiring diagram towards the back of this manual should be followed carefully. Heavy
duty conductors on wiring diagrams are shown heavily outlined, these wires should be
doubled up.
-
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.
-
All intercom and access control cables must be routed separately from the mains.
-
When the panel is mounted on an uneven surface, use additional sealant to protect from water ingress.
Lock release back EMF protection : A
capacitor should be fitted across the terminals on
an AC lock release as shown in the diagram
below to suppress back EMF voltages.
