Kidde Alarmline II Digital LHD EN54-28 Dual Zone Location

The Kidde AlarmLine digital location control unit is a dual zone module for monitoring up to 2 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 2 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 2-wire RS-485 Modbus RTU output. The unit supports the use of a interconnecting cable (leader cable) in between the control unit and the linear heat detection cable. The interconnecting cable is used in applications where the control unit is not located in the detection zone. The interconnecting cable is then used to connect the control unit in one location, with the linear heat detection cable in the protected area. The interconnecting cable is available in 100 m lengths, under the product code AAI-0100.
