Automatic Fire Detector in Threshold Alarm Technology
Installation
The detector bases are fixed on the ceiling with 2 screws,
after the corresponding preparations have been made.
The detector is mounted horizontally as standard.
The location of the mounting bores can be found in the
“Dimensional drawing” section.
During installation, it is important to ensure that the base does
not warp when installed on an uneven ceiling, as it may make
it difficult or impossible to plug-in the detector. The detector
is placed against the base and screwed onto the base in a
clockwise direction.
Cable connection
With flush-mounted cabling, it is necessary to ensure that all
the required conductors for standard wiring are located on the
“R+” terminal side. The incoming and outgoing conductors
can be inserted through the same aperture on the socket
base (also see the dimensional drawing).
With flush-mounted cabling, it is also advantageous if
both cables are inserted on the side of the base, where
the terminal “R+” and the terminals for all other standard
applications are located.
When introducing the cable from 2 sides, the location of the
base should be selected, so that the breaking points for the
cable entry on the base are offset longitudinally to the cable
path by 180 °. The individual wires can be fed both within the
base interior as well as from underneath the base, from one
half of the base to the other. Cables up to 2 x 2 x 0.8 mm
can be inserted to the base together with the sheath; thicker
cables will require removal of the sheath outside the base.
If the cable shield (sheath wire) of incoming and outgoing
cables is to be looped through, this must be implemented in
the base, e.g. using a ferrule or similar device.
Test activation
A test activation can be undertaken by holding a permanent
magnet at the smoke inlet aperture level (these are also
available on the heat detectors) located at about 100° in a
counter-clockwise orientation starting from the rectangular
opening on the side of the detector base on the detector.
Inspection/Maintenance
Every detector must be physically activated at least once a
year to test its function in accordance with VDE 0833 part 1.
A suitable testing aerosol is recommended for activation of
smoke detectors; heat detectors should be activated using a
heat gun or a hair drier.
