Cabling Information
Use the appropriate cabling for the lock equipment taking into account the distance and voltage
requirements. Please contact your cable supplier with your specification for more advice.
The lock suppressor must be connected as close as possible to the lock to avoid any
damage to the controller. A suppressor must be fitted at each lock (see above). Four
suitable suppressors (1N4007) are provided with each controller.
When using an external power supply for the locks, the lock suppressor must be connected
as shown on the wiring diagram above. For maximum reliability we recommend the use of
separate power supplies for locks. If using one supply for the controller and the lock(s) it
controls, no issue should occur provided the supply has sufficient output current and the
cabling distances do not result in significant voltage drops. Always run the power to the lock
in a separate cable.
