General Information

The enhanced Elmdene TR range of power supplies has been specifically designed for access control applications that require remote control of the power supply output. A typical example being where a TR power supply unit is used to power magnetic door retainers; utilising a signal from the fire panel in order to switch off the output to the doors in the event of a fire alarm activation. The units now have an expanded range of input options which includes the detection of a normally closed contact going open and also removal of a 24V dc signal to provide a fully fail safe operation mode (BS 7273 Compliant). The three control input options for remote control of the output are as follows: • Removal of an external 24V dc supply (BS 7273 Compliant) • Opening of a normally closed volt-free contact • Closing of a normally open volt-free contact LED status indicators provide quick diagnostics showing the presence of a mains input and output fuse failure.
