The XLM 35, SLM 35 and RIM 35 terminal assignments can be
found in the corresponding data sheets T 140 088 (XLM 35),
T 131 197 (SLM 35) and T 131 196 (RIM 35).
Wiring principle
Examples of and information on the wiring principle can
be found in the Technical description ASD 533,
T 140 287, Sec. 6.
Using the smoke sensor
The ASD 533 ships with the smoke sensor already fitted. The
smoke sensor has to be removed from the detector housing for the
installation of the ASD (release the two lock clamps); however it
should be left inside its protective packaging until the definitive
commissioning. The definitive installation is carried out as de-
scribed below, see
Fig. 3
.
•
Always leave the smoke sensor inside its protective
packaging until it is ready to be installed definitively in
the detector housing.
•
Depending on the circumstances (e.g. long period of
time between mounting and commissioning or if the
environment is extremely dusty (construction work)),
only remove the smoke sensor from its protective
packaging and insert it definitively in the detector
housing when commissioning the ASD 533.
•
Before installing the smoke sensor check that the in-
sect protection screens are properly fitted to the
smoke sensor chamber at the air inlet and outlet.
•
The smoke sensor chamber must be absolutely free
of any dirt and/or dust. Remove any residue resulting
from mounting the detector housing.
Check the installation position when installing the smoke sensor.
The smoke sensor connector plug must face the outside of the
ASD housing. The anti-twist rib on the smoke sensor case pre-
vents an incorrect installation position.
The smoke sensor is secured inside the ASD housing using the
two lock clamps. Connect the ribbon cable supplied with the smoke
sensor to the smoke sensor (large ribbon cable connector) and to
the AMB 33 main board (small ribbon cable connector).
Smoke sensor chamber II in the housing base cannot be used (air
duct is blocked).
