Installation Smoke Detector
ELQZ-2-428-2, GOLD
General
The ELQZ-2-428-2 smoke detector is used for measuring
any smoke present in ventilation ducts. It consists of an
ionising detector mounted in an adaptor system where
both the tube and enclosure are designed for optimum
airflow through the detector. The system meets all the
fire safety requirements for air velocities between 0.2 m/s
and 20 m/s. The smoke detector is used together with a
control unit (fitted inside an ELQA equipment cubicle or a
separate equipment cubicle for the smoke detection and
warning function) for controlling fans, fire and smoke
dampers.
Operation
If any smoke is detected, a red LED on the detector lights
up and the detector transmits an alarm signal to the con-
trol unit.
Any accumulation of impurities in the smoke detector will
make it more sensitive and gradually approach its alarm
condition. To avoid unnecessary alarms caused by fouling,
the detector is equipped with a service alarm (green LED).
When lit, this LED indicates that the detector ought to be
cleaned.

Accessories
The ELQZ-1-428-2-1 Mounting bracket should be used for
mounting the detector on a circular or insulated duct.
Maintenance
Whenever the smoke detector becomes fouled, it will be
more sensitive and may trip the service alarm. This situa-
tion can easily be delayed by vacuum cleaning the detec-
tor once a year.
