AACULP Alarmline II Analogue LHD Control Unit - PC Programmable
Interface & Programming
The AACULP provides LED indications only and requires a PC to
configure the control unit.
Pre-Alarm and Alarm thresholds can be set through simple menu
options with no need for any graphs or nomograms. Initial set-up is
done by measuring and entering the calibration resistance of the
sensor cable removing the need to know the sensor cable length.
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. When the LHD
sensor cable and the control unit are installed in different areas, a
suitable interposing cable can be used to make the electrical
connection between them.
