TR/TRS Range

24V Power Supplies for Fire and Access Control Applications

Designed for fire and access control applications that require control of the power supply output.

A typical example being where a TR or TRS power supply unit is used is to power door retainers, with a link to the fire panel in order to switch off the output to the doors in the event of a fire alarm activation.

The units 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.
