General
The AlarmLine II Analogue EN Linear Heat Detection (LHD) system comprises of AlarmLine II Analogue EN Linear Heat Detection (LHD) sensor cable (AAE-xxxx), a AlarmLine II Analogue EN Controller (AAECU) and a AlarmLine II Analogue EN end of line unit (AAECU-EOL). The controller provides monitoring of the AlarmLine II Analogue EN range of LHD sensor cable, configuration of alarm and pre-alarm temperatures as well as enabling simple interface to a main fire alarm or BMS system.
Interface & Programming
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.

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 signaled.
Each control unit may have up to 500m (1640ft) of LHD sensor cable connected to it, acting as a single detection zone.

Details
The AAECU is supplied with an End-Of-Line unit (AAECU-EOL) 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.
