General Overview
AlarmLine II Digital EN Controller
The Kidde AlarmLine II Digital EN Controller is a dual zone module for
monitoring up to two zones of Kidde AlarmLine II Digital EN Linear Heat
Detection (LHD) Cable. If an overheat or re situation triggers either zone
of the Digital LHD 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 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 re 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/ASCII output.

Overview
The AlarmLine II Digital EN Controller allows accurate location of an alarm point along a length of Kidde AlarmLine II Digital EN Linear Heat Detection
(LHD) cable. It continuously monitors up to two zones of Digital LHD cable for a fault (open circuit) or an alarm (overheat or re condition). Because of the
wide range of applications that Digital LHD cable can be used for, it may not always be possible, or be too time consuming, to locate where along the cable
an alarm has occurred. Using the AlarmLine II Digital EN Controller, when an alarm occurs the distance to the overheat condition is immediately calculated
and displayed on the integrated display.
If a fault is detected, the corresponding fault output stops conducting, triggering a fault at the re alarm control panel. If an alarm is detected, the
corresponding alarm output changes state, triggering an alarm at the re alarm panel. The fault outputs also stop conducting on power loss to the unit or
microprocessor fault, triggering a fault at the re alarm control panel.
The two wire RS-485 Modbus RTU/ASCII output also outputs the current state of both zones. See the section “Modbus RTU/ASCII Communications” for
more detail.
There are two primary congurations of the AlarmLine II Digital EN Controller (see gure 1):
1) The Digital LHD cable can be connected directly to the AlarmLine II Digital EN Controller
2) The Digital LHD cable is connected to a length of leader cable which is connected to the AlarmLine II Digital EN Controller. In this scenario the
leader cable must be “calibrated out” during commissioning of the AlarmLine II Digital EN Controller.
Connections Diagram
Figure 3 shows the connections diagram for the AlarmLine II Digital EN Controller. The unit is provided with a 3.6kohm end of line resistor in each zone
input. If only one zone is required, leave the 3.6kohm resistor connected across the zone which is not in use. Otherwise the 3.6kohm resistor should be
connected at the end of the Digital Linear Heat Detection cable.

Operating Modes Wiring Diagram Independent
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. The two zones operate independently and both sets of outputs should be connected
to a re alarm control panel. If the zone is not required leave the 3.6kohm resistor in the zone input terminals as supplied. In this mode, the two zones can
either contain identical rated temperature Digital LHD cables or two different rated temperature Digital LHD cables.

Operating Modes Wiring Diagram Interlock
2. Interlock – this mode is for applications which require a fail-safe guarantee that an alarm is only triggered when an overheat condition has been detected.
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. This is to prevent an alarm if a mechanical or
other issue has triggered one Digital LHD cable and not an overheat condition.
• Only use Zone 1 fault and alarm outputs in Interlock mode.
• Two linear heat detection cables with the same temperature rating must be used and a
minimum of two linear heat detection cables must be installed in each protected space.
See the AlarmLine II Digital EN LHD Installation Instructions for the linear spacing specication.

Leader Cable
In certain applications it may be desirable or necessary to use non-
sensing leader cable between the AlarmLine II Digital EN Controller
and the Digital LHD cable. For example, if the the AlarmLine II Digital
EN Controller is located some distance away from the area protected
by the Digital LHD cable. This may be required if the expected ambient
temperature range, or other environmental conditions, where the
Digital LHD cable is to be used is greater than the maximum ambient
temperature range for the AlarmLine II Digital EN Controller. (see steps 8,
9 and 10 in the Commissioning section on pages 10-11).
The maximum length of leader cable that can be used per zone is
dependent upon the leader cable diameter’. The following is a guideline
for typical cable sizes and maximum length:
Leader Cable Size Max Leader Cable Length
20AWG
(16x0.2mm or 0.8mm dia, copper) 1000m
Mounting Dimensions
The AlarmLine II Digital EN Controller is intended to be wall-mounted.
4 holes should be drilled according to the mounting dimensions given in
gure 2. The corresponding mounting holes on the AlarmLine II Digital
EN Controller can be found by removing the lid of the device. The
mounting holes are located adjacent to the lid screw positions. Suitable
screws for the type of wall the AlarmLine II Digital EN Controller is to be
mounted on will need to be provided for separately. The maximum screw
head diameter is 7mm and the maximum screw thread diameter is 4mm.
Static Discharge Cautionary
The following items are cautionary notes that will help prevent
equipment damage or malfunction caused by static discharge:
CAUTION
Static charges produce voltages high enough to damage electronic
components. Follow these precautions when installing, servicing, or
operating the AlarmLine II Digital EN Controller:
• Work in a static-free area.
• Discharge any static electricity you may have accumulated.
• Discharge static electricity by touching a known, securely
grounded object.
• Do not handle the printed circuit board (PCB) without proper
protection against static discharge.
In the event that the AlarmLine II Digital EN Controller malfunctions after
encountering a static discharge correct operation of the unit can be
restored by interrupting power to unit for a brief period (approximately
10 seconds). Setup information can be veried by following the steps in
the Commissioning section (page 10 onwards). In the event of the setup
information being corrupted the unit should be reset following the
Resetting the AlarmLine II Digital EN Controller procedure.
