The Kidde ADELCU-2 is a dual zone module for monitoring up to two zones of AlarmLine II Digital EN Linear Heat Detection Cable. If an overheat or fire situation triggers either zone of the digital cable the unit automatically calculates and displays the distance along the cable, in feet and metres, to the alarm point. The two zones can operate independently of each other, or in interlock mode. A separate alarm and normally conducting fault output are provided for each zone. The unit is intended to be installed between the AlarmLine II digital EN linear heat detection cable and a conventional or addressable fire alarm control panel. It has power, fault and alarm indicators, as well as free outputs for fault and alarm, corresponding to each zone. It may also be connected to an industrial process control system using the two-wire RS-485 Modbus RTU output.
