Only use Kidde AlarmLine II Digital EN Linear Heat Detection cable with the AlarmLine II Digital EN Controller. Test the Digital Linear Heat Detection cable before connecting it to the AlarmLine II Digital EN Controller using a multimeter. Ensure the end of line resistor (3.6kohm) is securely connected at the end each linear heat detection cable. -
Page 4: General Overview
General Overview AlarmLine II Digital EN Controller The Kidde AlarmLine II Digital EN Controller is a dual zone module for each zone. The unit is intended to be installed between the Digital Linear monitoring up to two zones of Kidde AlarmLine II Digital EN Linear Heat Heat Detection cable and a conventional or addressable fire alarm Detection (LHD) Cable. -

Page 7: Operating Modes
There are two operating modes for the AlarmLine II Digital EN Controller: 1. Independent – This is when the AlarmLine II Digital EN Controller is used as a two zone system. When a fault or overheat condition occurs on a Digital LHD zone, the corresponding fault or alarm output respectively is triggered. - Page 8 This mode may also be known as coincidence detection. In this case, the same rated temperature Digital LHD cable should be attached to both zones of the AlarmLine II Digital EN Controller. The alarm output is only activated when both Digital LHD cables trigger an alarm due to an overheat condition. If one Digital LHD cable zone input registers an alarm but the second does not, the alarm output will not be activated.

Zone 1 ldr cable hazardous area and IS barriers are being used, the voltage drop to the start of the LHD cable must be measured by the AlarmLine II Digital EN Controller in order to ensure correct operation and accurate distance location. - Page 11 Commissioning (Cont.) 9. If “Yes” was selected in step 8, the AlarmLine II Digital EN Controller will then ask if the zone is ready to be calibrated. Ensure that the connection Ready to between the leader cable and/or the IS barriers and the start of the calibrate? Digital LHD cable is securely shorted out between the two cores.
