Power Supply Requirements

The system is powered by 12V PSU’s only: -

PS4 12V, 4A

340C 12V, 1.5A Optional for extensions

Note 1. The 28V refered to on the videophone, door controller and wiring diagrams

is internally generated in the controller. DO NOT use any PSU other than 12V or

damage may occur.

Note 2. The PS4 power Supply has been specifically designed to operate with the

high-surge requirements of the system. Bell Systems are unable to guarantee

functionality or provide support for systems which use third party power supplies.

Exact power supply requirements depend upon many factors. The number of power

supplies included within a standard ‘kit’ assumes that all controllers are installed in

one location and that there are no extensions.
