Installation instructions for the optical detector with built-in
control unit, TBLZ-1-72-a
GOLD/COMPACT
1. General
The TBLZ-1-72-a optical smoke detector with built-in control unit
is used for measuring 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
detector also has a built-in control unit for controlling fans, fire
and combustion gas dampers.
Accessories
Use an installation bracket when installing on circular or insulated
ducts.
2. Function
A green LED is lit on the control unit's circuit card when the unit is
operating in the normal mode. All the relays are activated.
When combustion gas is detected, a red LED lights up on the
circuit card and detector.
If the smoke detector becomes dirty, it becomes more sensitive
and slowly switches to alarm mode. To prevent false alarms if dirty,
the detector is equipped with a service alarm (green LED on the
smoke detector and yellow LED on the circuit card of the control
unit). This indicates that the detector requires cleaning.
If a malfunction arises, the green LED will be off and no relays
will be activated. Example: If the smoke detector is removed or a
power failure occurs.
A tripped alarm can be reset on the rear side of the smoke detec-
tor. See illustration.
