EN54-22 Control Unit
Part Number: P-AAECU
EN54-22 is a referenced standard in AS1670.1 2018 and 2024 versions
Adjustable temperature setting for linear heat cable please refer page 6 of instruction manual download.
The AAECU provides LED indications as well as a LCD. Internal pushbuttons allow for easy configuration without the need for a PC. Configuration via PC is also supported via a USB connection and the optional configuration software AAECU-PCC. Pre-Alarm and Alarm thresholds can be set through simple menu options. Initial set-up is done by measuring and entering the calibration resistance of the sensor cable, as well as the 3 letter cable parameter identifier. Volt free changeover contacts are provided inside the control unit for Pre-Alarm and Alarm signaling to a main fire alarm control panel or BMS system. A failsafe opto-isolated phototransistor fault output is also provided. No user controls are provided on the control unit. An isolated input is provided enabling remote reset functionality.
This control unit can only be used with the P-AAE-0100, P-AAE-0500 and/or P-AAE-XXXX

Product Information
Operation
As well as monitoring the LHD sensor cable for changes in temperature, the control unit also monitors for open and short circuit faults along the cable ensuring notification if the cable becomes damaged. It is fitted with its own internal temperature monitor and should the temperature within the controller enclosure reach 100°C (212°F), an alarm will be signalled. Analogue EN Control Unit Alarmline II Series Each control unit may have up to 500m (1640ft) of LHD sensor cable connected to it, acting as a single detection zone. detection per control unit. The controller is compatible with any conventional or addressable fire alarm panel or other building management system.
Details
The AAECU is supplied with an End-Of-Line unit (AAECUEOL) included. The End-Of-Line unit (AAECU-EOL) is also available separately as a spare part. A junction box (AAECU-JUN) is also available separately, if two pieces of cable needs to be joint.
