A control cabinet for an audio system will contain a 13.8Vdc PSU with battery back up

facility. The standard power supply is rated at 1 Amp. (Care should be taken to calculate

the current consumption of the lock release as it may be necessary to upgrade this power

supply to either a 2 Amp or even a 3 Amp). Video control cabinets will have an additional

PSU rated at 20Vdc 1 Amp surge or 800mA continuous. This additional power supply is

described below and is used to power the videophones and the camera.
