ASD 533
Aspirating Smoke Detector
As of production version 200619 and FW version 01.08.xx
The ASD 533 aspirating smoke detector has the task of continu-
ously taking air samples via a sampling pipe tube network from a
monitored area and feeding the samples to a smoke sensor.
The ASD 533 consists of the detector housing and a sampling pipe
tube network. The sampling pipe has several sampling holes
whose size is such that each hole extracts the same amount of air.
The sampling pipe may be I-, U-, T-, H-, or E-shaped. The sam-
pling pipe is symmetrically designed in principle. Asymmetrical
sampling pipe tube networks can also be implemented using the
“ASD PipeFlow” calculation software.

Description
Integrated in the detector housing is a high-performance fan which,
in conjunction with the sampling pipe, ensures an uninterrupted air
supply to the detector housing. Airflow monitoring detects any pipe
blockages and pipe breakages in the sampling pipe.
The ASD 533 aspirating smoke detector is part of the ASD 535
product range and is available in a version for 1 sampling tube and
1 smoke sensor without smoke level indicator. The exact designa-
tion for the aspirating smoke detector is therefore
ASD 533-1
. The
present document will however refer in principle to the product des-
ignation
ASD 533
.
The ASD 533 uses the
SSD 533
smoke sensor, which has an
alarm sensitivity of 0.02%/m to 10%/m.
The ASD 533 aspirating smoke detector has four slots for addi-
tional modules. The following modules can be fitted:
•
XLM 35
SecuriLine eXtended Module;
•
SLM 35
SecuriLine Module;
•
RIM 35
Relay Interface Module with 5 relays (max. 2
units);
•
MCM 35
Memory Card Module
The ASD 533 can be connected to a higher level FACP via poten-
tial-free change-over contacts.
Fitting an
XLM 35
or
SLM 35
means that the ASD 533 can be ide-
ally connected to the SecuriFire and Integral fire alarm systems via
the addressable loop (with SLM also to the SecuriPro).
The
RIM 35
is available as a further installation option. This mod-
ule enables the availability of all three pre-signal levels as well as
the states “smoke sensor dirty” and “LS-Ü blockage” as relay con-
tacts. The relays are also freely programmable via the
„ASD Config” configuration software.
The
MCM 35
is used for storing operating data.
The ASD 533 aspirating smoke detector can be used for:
•
Equipment monitoring
: EDP systems, electrical distributors,
switch cabinets, etc.
•
Space surveillance
: EDP rooms, ultra-clean rooms, warehou-
ses, hollow floors, protection of cultural assets, transformer sta-
tions, prison cells, etc.
The ASD 533 is also deployed in areas where conventional point
detectors are normally used. Local regulations and provisions must
be observed from case to case.
The response behaviour of the ASD 533 has been tested in com-
pliance with EN 54-20, Class A, B and C.
When setting up ASD 533 fire alarm systems, it is impor-
tant to take note of and observe the information and
specifications in the “
Technical description ASD 533
”.

Opening the detector housing
To actuate the
rotary snap locks
use a Phillips screw-
driver (at least No. 5) to
press down firmly
towards the
housing base and then
turn
90°. The position of the lock
slit shows the current status:
•
angled approx. 45° toward detector housing corner =
closed;
•
angled approx. 45° toward detector housing edge =
open.
In either position the rotary snap locks
must
snap into
place.
The
housing cover
(control unit) is connected to the
main board by a
ribbon cable
. Make sure the ribbon ca-
ble is not damage when the housing cover is lifted off.
