Digitac PSU/Controller 1M

The Digitac access psu/controller contains the power supply and electronic circuitry for an access control system which is operated from a ten digit entry keypad mounted outside the protected area. The control unit is mounted in a secure area. The common four digit code held in the memory of the system can be changed easily and as often as required by authorised personnel. This plus the fact that the code is neither accessible nor visible provides a relatively high level of security on a simple system. The memory is protected by a key operated switch on the main control unit. The four digit code can be changed by inserting the key and turning it to the programming position. Any four digit code entered on the keypad whilst the key is in this position will replace the previous code. The new code is confirmed in the system simply by returning the key to the 'ON' position and removing the key.
