Smoke detector installation TBLZ-2-49-a
GOLD/COMPACT

1. General

Smoke detector TBLZ-1-49-a is used to measure smoke
gases in ventilation ducts. It consists of an optical detector
mounted in an adapter system in which both the tube and
enclosure are designed for optimum airflow through the
detector. The system meets all fire safety requirements at
air speeds between 0.2m/s and 20m/s. The smoke detec-
tor is used together with a control unit (installed in equip-
ment cubicle ELQA or separate equipment cubicle for
smoke function) for controlling fans, smoke and combus-
tion gas dampers.
Accessories
Use an installation bracket when installing on circular or
insulated ducts.

2. Function

When combustion gas is detected the LED on the detector
lights red and the alarm signal is forwarded to the control
unit.
If the smoke detector becomes dirty, it becomes more sen-
sitive and switches to alarm mode more slowly. To prevent
false alarms if dirty, the detector is equipped with a service
alarm (green LED). This indicates that the detector requires
cleaning.

4. Maintenance

When the smoke detector becomes dirty, it becomes more
sensitive and may trigger the service alarm. This can be
delayed by vacuuming the detector once a year.
