Installation Instructions - UNIGUARD
UG-Bracket for circular or insulated rectangular ducts.
Using the UG-Bracket the diameter of the duct can be as small as 100 mm.
Drill a hole
Ø 35 mm.
Drill a hole
Ø 35 mm.
Diameter of the duct bigger
than 0,6 m.
The venturi pipe should
penetrate the whole duct.
Max diameter of the duct 0,6 m.
Use the venturi pipe 0,6 m.
Shorten the pipe, if necessary.
Mounting and Positioning.
Fix
the bracket
on to
the duct.
The Uniguard should be installed with the arrow on the
cover corresponding to the direction of airflow in the duct.
The Uniguard can be placed horizontally or vertically,
on the top, side or bottom of the duct.
Drill a hole
Ø 50 mm.
The UG-bracket can easily be bent or shaped
to fit a circular or rectangular duct.
Shorten the pipe to correct length.
We recommend that the Uniguard is mounted at an equal
distance from heating, cooling, or humidy devices, and
similar to the siting for flow monitors.
A distance of 3 times the duct diameter should be left before
a damper, filter or change of the duct direction, and 5 times the
diameter after these devices.

Insert the end plug.
Put on the end plastic
gasket.
The UG-Bracket is supplied flat.

Put on the rubber
gasket, TET 26-35.
For ducts with a ø of less than 0,6 m use the 0,6 m tube.
For ducts with a ø of between 0,6 m and 1,4 m use the 1,5 m tube.
NOTE!
For ducts which are larger than 1,4 m use the 2,8 m tube.

problems could arise due to temperature

Outdoor positioning.
Where large temperature variations occur,
e.g. on outdoor locations or in areas subject
to external temperatures (roof, attics),
the Uniguard should be insulated, see para 11.

• The arrow of the cover must have the same direction as the airflow in the duct.
• Check that the rubber gasket between the cover and bottom of the Uniguard is air-tight.
Example of location
• Check that the plastic plug of the test hole is air-tight.
• Check that the flow indicator oscillates ensuring proper air flow through the detector.

• It is recommended that smoke from a smoke generator is introduced into the duct to
check the function of detector.
• Check that the end resistor is mounted in the last smoke
detector.
• Check that the resistance is 2,2 kOhm.
• Check that there are no bad connections or short circuits
in the loop.
• Check that the control unit is OK by placing the 2,2 kOhm
resistor directly on the control unit.
• Check with a voltmeter, that 24VDC is present in the
detector base. Note! The voltage must have the correct
polarity.

NOTE!
The indicator oscillates
but does not rotate.
If the indicator does
not move, you should
check your positioning
of the Uniguard.
Do not shorten this end.

(The arrow of the fan
shall point down at the

Check the detector with smoke
from a match or approved testgas like Calectro´s RDP-300.
• Measure the diameter of the duct.
• Shorten the pipe, if necessary. The pipe should
penetrate approx 90% of the width of the duct.
NOTE! See para 10.
• Insert the end plug.

• Mount the gasket on the pipe.
• Put the pipe into the buttom of the Uniguard.
NOTE - IMPORTANT!
The arrow on the Uniguard cover
must have the same direction
as the airflow in the duct.
Fitting of cover.

Electrical installation.
Do not drill any holes in the cover for signs etc.
Holes will cause air leakages and seriously
disturb the function of the detector.

Connect the cables according to
the wiring diagram.
When using Calectro´s control units.
• Mount the Uniguard with its pipe on the duct.
• Secure the bottom of the Uniguard with the 3 locking screws.
(Positions marked.)

If only one smoke detector is connected to the control unit,
this detector should be provided with a resistor (2,2kΩ).
When several smoke detectors are connected to one control
unit, the end-of-line resistor (2,2kΩ) should be connected in
the last smoke detector. Only one resistor per loop.
