12.4 Functional check of the loop

1. Start the control panel by switching the power on. First connect the transformer cable, then the battery cable.

2. Wait until the text “PANEL STARTING UP” disappears from the display (about 3 minutes).

The detector loop is in order if the control panel does not give fire, fault or service indications at the start up.

Otherwise the fault must be located by following the instructions below.

3. If the panel indicates fire alarm, press the “BUZZER

SILENCE” button, scroll the alarm indications with the

“MORE ALARMS”- button and note them.

4. Eliminate the causes of fire alarm and reset the indications by pressing the “RESET”- button until the pulsed signal stops.

Possible causes for fire alarm:

- A manual call point is pressed down; the glass has been broken or taken off.

- Smoke, water vapour or thick dust in a smoke detector.

- Heat close to a heat detector.

5. Repeat the above mentioned procedures until there are no more fire alarms.

6. If the panel indicates fault or maintenance warning press the “BUZZER SILENCE” button, scroll the indications with the “MORE ALARMS”- button and note them.

Possible causes for fault warnings:

- A break or a short circuit in the loop.

7. Eliminate the causes of fault and maintenance warnings and reset the indications by pressing the “RESET”- button until the pulsed signal stops.

8. Repeat the above mentioned procedures until there are no more fault and maintenance warnings.

9. Test that each detector and manual call point gives an alarm. Test procedures for the various devices are given in the documentation for those devices.

- An earth leak in the loop.

Note!

CLC default value for the short circuit is a fault!
