Installation bracket TBLZ-1-53 for circular ducts or
insulated flat ducts.
The duct diameter can be as small as 100 mm
using the bracket.
• Check that the direction of the arrows is towards the direction of flow.
• Check that the plug for the test hole is properly installed.
• Check that the flow indicator shows flow (rocks).
• Full scale tests with smoke generator are recommended to check the function.
Troubleshooting.
The smoke detector deploys without any smoke
present.
• The smoke detector is faulty, dirty or positioned so that
condensation can build up, see point 8. The detector
insert must be replaced.
Only the control unit triggers an alarm.
• Check that the termination resistor is installed in the last
smoke detector.
• Check that the coil’s resistance is 2.2k
Ω
from the control
unit.
• Check that the control unit is OK by installing the 2.2k
Ω
resistor in the smoke detector output on the control unit.
• Use a voltmeter to check that 21-24 VDC with the cor-
rect polarity is in terminal 1 (-) and terminal 2 (+).

Max. tube of 30 mm outside the duct.
For ducts less than 600 mm use ven-
turi tube of 600 mm, standard.
For ducts between 600 mm and 1400
mm, use venturi tube of 1500 mm.
