The SafeCable Alarm Distance Locator Module (DLM-Z2) is a dual zone module for monitoring up to two zones of The SafeCable Digital Linear Heat Detection (LHD) Cable. If an overheat or fire situation triggers either zone of the LHD cable the unit automatically calculates and displays the distance along the cable, in feet and meters, to the alarm point. The two zones can operate independently of each other, or in interlock mode and a separate alarm and normally conducting fault output are provided for each zone. The unit is intended to be installed between the Digital Linear Heat Detection cable and a conventional or addressable fire alarm control panel. It has power, fault and alarm lights, as well as volt free outputs for fault and alarm, corresponding to each zone. It may also be connected to a industrial process control system using the two wire RS-485 Modbus RTU output • UL Approved • Can be One or Two Zones • Single or Cross Zone • Displays in Feet or Meters • Built in MODBUS Interface • Each Zone Can Use The Same or Different Temperature Cables • If Two Different Temperatures Are Used, one can be a Pre-alarm • Can be used with ANY UL Listed Panel
