ELQZ-1-428-2-1 Mounting bracket for a circular duct or an insulated rectangular duct.
The mounting bracket enables the detector to be installed on a duct
having a diameter as small as 100 mm.
FINAL INSPECTION
Fault tracing.
The smoke detector indicates a service alarm.
• The detector has become fouled and needs to be clea-
ned. This can appropriately be done by vacuum cleaning
or by carefully blowing surfaces clean with compressed air.
• The service alarm may trip sooner than expected if the
newly installed ducting hasn’t been properly cleaned
before the system is commissioned.
The smoke detector initiates an alarm when no
smoke is present.
• The smoke detector has been located where condensa-
tion can form inside it, such as outdoors, in a cold attic, a
kitchen or the like.
An alarm is indicated by the control unit only.
• Measure the resistance of the loop (2,2k
Ω
) from the
control unit.
• Check that the control unit is OK by wiring the final resistor
to the smoke detector output on the control unit.
• Use a voltmeter to check that 24 V DC with the correct
polarity is present in the socket below the detector.

• Make sure thatthe arrow on the detector cover points in the direction of airflow.
• Check that the cover and its gasket seals properly against the base and that nothing is lodged in between
them, such as insulation.
• Check that the plug is properly seated in the test hole.
• Check that the flow indicator indicates airflow (is rocking).
• It is advisable to test the performance of the detector in full scale.
