Loop Tester –Technical and Operation Manual

1. Introduction

1.1. General Description

The Loop Tester is a diagnostic tool specially designed for operation with addressable devices SensoIRIS 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 SensoIRIS 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.

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.

4. Select the option “Unaddressed loop” and confirm. Starting the procedure, the Loop Tester will set

sequential addresses to the devices according their order in the loop.

Note: You can run the addressing procedure again and change the set addresses later, when the loop is finally

connected to the fire alarm control panel.

4.3.2 Reading of Addressed Loop/Line (Present installations)

Attention: When you use the Loop Tester for diagnostic of present and already operating fire alarm

installation, it is strongly recommended first to save the existing configuration using specialised ProsTE

programming software!

To perform testing of a present installation (addressed devices) follow the steps:

1. Read the panel configuration with ProsTE software and save it as *TDF data file.

2. Power off the fire panel.

3. Disconnect the loop wires from the loop expander terminals.

4. Connect the loop/line wires to the Loop Tester terminals as described in item 3.1.

5. Switch on the Loop Tester.

6. Enter in menu “Loop Test” and choose sub-menu “Loop Tools”. Select a test and press ENTER.

7. Select the option “Addressed loop” and confirm.

4.4. Perform Cable Tests

This is a menu for performing test of the fire cable used in the installation. The test can be fully automatic or

manually selected separate single tests for different electrical values. It is recommended to run first the automatic

test for reviewing the general state of the cable and then, if it is necessary, to proceed with single tests.

The performed tests are for searching breaks, short circuits or earth fault of installed cable, which can disturb the

operability of the loop line.

Attention: The tests must be performed with no connected devices to the cable. If there are connected

devices, they have to be disabled or dismounted before running the desired tests.

Select Cable test menu and confirm with the ENTER button. Then choose auto or single cable test.

Solution

Short-circuit in the cable

Run singe test “Test for Short”

again to confirm the presence

short-circuit in the cable. In case of

fault the tester will display message

“Short in Cable”.

To locate the place of the short-

circuit fault use Bisection method

as dividing the cable in equal parts

(1/2, 1/4, 1/8, etc), until finding the

faulty section. See also item 4.5.3.

Break in the cable

Run singe test “Test for Break”

again to confirm the presence

break in the positive or negative

cable wire. In case of fault the

tester will display message “Break

in Cable”.

To locate the place of the break

use Bisection method as dividing

the cable in equal parts (1/2, 1/4,

1/8, etc), until finding the faulty

section. See also item 4.5.3.

Earth fault in the cable

Run singe test “Leakage to Earth”

again to confirm the presence earth

fault in the positive or negative

cable wire. In case of fault the

tester will display message “Earth

fault”.

Search the earth fault as inspect

the grounding components in the

cable line, corrupted shield of the

cable, etc.

You can also use and the Bisection

method described in item 4.5.3.

Too High resistance

According the result in the Auto

Cable Test menu run the single test

for:

“R+ Cable”

“R- Cable”

“R Earth Cable”

In case of unusual high resistance

found the tester will display

message “R+/R-/Re=Too High”.

The error message “Too High” is

displayed when the detected

resistance in the positive cable

wire (R+), negative cable wire (R-)

or earth cable (Re) is higher than

400 Ohm. In such cases, it is

recommended to check the cable

and the joint connections

(terminals, base contacts). Check

also the cable length –it might be

too long.

4.5 Perform Loop Tests

This is a menu for performing test of the loop and the connected devices. It is recommended to run first the “Loop

state” automatic test for reviewing the general state of the loop and a list of the connected devices. The general

review will help you at the beginning to orientate for current faults, possible breaks or short-circuits in the loop, the

number of connected devices and troubles with them.

Attention: To perform more precise tests it is obligatory to use the built-in isolator module for all modules

and call points connected to the loop. It is recommended to use detectors and sounders with bult-in isolator

module (see the table in the Appendix). In installations where, detectors and sounders without built-in

isolators are already being used, the results for searching branches and localization of short-circuits and

break in the loop can be uncertain. In this case it is recommended for more precise results in searching of

errors to be performed and the bisection method (see item 4.5.3).
