1. Introduction
1.1. General Description
The Loop Tester is a diagnostic tool specially designed for operation with addressable devices Comelit series. The
device is suitable for testing the continuity and the technical characteristics of the fire cable and also the operability
of the loop and the connected devices.
The Loop Tester can operate with only one loop line. The switching between the loops of the panel is very easy
using the supplied clamp terminal blocks.
The time for test may vary according the length of the loop and the number of the connected devices.
Important notes:
During the test the loop line must be disconnected from the control panel!
DO NOT connect the fire control panel and the Loop Tester to the loop line simultaneously!
The cable tests have to be done without connected devices to the loop line! If the cable tests are
made with connected devices, you must consider that the measured results would not be exact.
For exact results in searching short circuits faults, breaks in the loop line and existing branches is
mandatory all devices in the loop/line to be with built-in isolator module – see the corresponding
table for Comelit addressable devices in the Appendix.
In case of installed devices without isolators in present operating fire alarm systems, you have to
consider that they will be displayed as separate branches in the system. When you have to search
for branches in a system including devices without connected isolator, we recommend to remove
them temporally before starting mentioned above test procedures.

Conductor wire, red, 120mm, 1.5mm2– 2 pcs
Conductor wire, black, 120mm, 1.5mm2– 2 pcs
1.4. Preparing the joint connections
The Loop Tester is delivered with a set of wires (2 red and 2 black) and clamp terminals for easier connection to the
loop line. You can prepare the joint connections in advance and then follow the description in item 3. Connection
diagrams. Use conductor wires with cross-section from 0.14 to 4.00 mm².
Strip the wire to 11 mm length.
Lift the lever to open the clamp block.
Insert the stripped wire.
Push the lever backwards to close
the clamp block.

3. Connection Diagrams
3.1. Loop Connection
Attention:
The loop line must be disconnected from the control panel before
connection to the Loop Tester!
DO NOT connect the fire control panel and the Loop Tester to the
loop line simultaneously!
Connect the four ready joint connections (clamp terminal + wire) to the
terminal row of the Loop Tester as strictly observe the polarity.
Connect the loop ends (side A and side B) to the respective clamps
connected to the terminal row of the Tester. Connect the shield ends
of the loop wires to the GND ( ) terminals of the Tester.
In case of a connection to a single line, connect to the Loop Side A
terminals of the tester, and use bridge connections along to Loop side
B terminals.

4. Operation with the Loop Tester
4.1. Switching on the Tester
Power on the Loop Tester with the switch (item 2.1, position 5) moving in ON position. The display will show for a
while the software version of the device and then will display the main operation menus.

switch to the new set language.
4.3. Reading a Topology of a Loop/Line
The Loop Tester operation (test and addressing procedures) always starts from Loop Side A to Loop Side B – see
item 3.1. A list with avaliable devices in the loop/single line is reviewed in menu Loop Tests – Loop State (see item
4.5.1). The devices are displayed as a list according their set address in the system.
4.3.1 Reading of Unaddressed Loop/Line (New installations)
The advantage of the Loop Tester is that it is possible to read and test the characteristics of the fire cable,
connections in a loop or a line, and the mounted addressable devices for the site in advance, before connection to
the fire alarm control panel. In new installations the connected devices have no set addresses and the technician
has to address them first to perform the loop testing.
To perform testing of a new installation (unaddressed devices) follow the steps:
1. Connect the loop/line wires to the Loop Tester terminals as described in item 3.1.
2. Switch on the Loop Tester.
3. Enter in menu “Loop Test” and choose sub-menu “Loop Tools”. Select a test and press ENTER.
