The TRS Range is a regulated DC Power Supply available in 2 & 4 Amp. A mains present indicator (Green LED) and fault indicator (Red LED) are provided. Remote switching of the 24 volt dc output can be achieved by means of either an external contact (opening or closing) or an external 24 volt DC switched supply. The latter is frequently used when switching DC Electromagnetic Door Retainers. The ideal application is to power Fire Door Hold Open Magnets, which will be released on activation of the Fire Alarm. The TR will provide a nominal 24 volt dc supply at its maximum output current for the operation of 24 volt field equipment. Note: This product is not for use with back-up batteries.
