1 General
1.1 Purpose
The ASD 532 aspirating smoke detector has the task of continuously taking air samples via a sampling pipe tube network from
a monitored area and feeding the samples to a smoke sensor. Thanks to this detection method and the product’s excellent
properties under severe ambient conditions, the ASD 532 aspirating smoke detector is used wherever problems are to be ex-
pected owing to poorly accessible monitored areas or latent disturbance variables during operation such that optimal protec-
tion can no longer be guaranteed with conventional point detectors.
The SSD 532 smoke sensor is used in the ASD 532. It is available in the three following versions and sensitivity ranges:
•SSD 532-1 Alarm sensitivity range 0.5%/m to 10%/m
•SSD 532-2 Alarm sensitivity range 0.1 %/m to 10%/m
•SSD 532-3 Alarm sensitivity range 0.02%/m to 10%/m.
The ASD 532 aspirating smoke detector has two slots for additional modules. The following modules can be fitted:
•XLM 35 eXtended Line Module
•RIM 36 Relay Interface Module with 5 relays;
•SIM 35 Serial Interface Module.

1.3 Opening and closing the detector housing
Warning about opening and closing
•
To open the detector box, use a flat-blade screwdriver no. 5 (8 mm). Smaller flat-
blade screwdrivers may
damage the material of the rotary snap locks.
•
To actuate the rotary snap locks, press them firmly
with the screwdriver towards the housing base and then
turn through 90°. The position of the lock slit shows the current status (see Fig. 1):
⇒approx. 45° angled toward detector housing corner = closed;
⇒approx. 45° angled toward detector housing edge = open.
In either position the rotary snap locks must snap into place.
Fig. 1Open, closing and securing the detector housing
The detector housing has to be opened for commissioning the ASD 532 (see T 140 421, Sec. 5.4.1).

1.4 Removing and mounting the smoke sensors
Check the installation position when installing the smoke sensor. The connector plug of the smoke sensor must be face away
from the slots of the additional modules. The anti-twist rib on the smoke sensor case prevents 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 32 main board (small ribbon cable connec-
tor).

2 Maintenance and service
2.1 General
Warning
Maintenance and service work on fire alarm systems are subject in part to country
-specific laws and directives.
Maintenance and service work may be performed only by persons trained and authorised by the manufacturer of
the
ASD 532.
Depending on application, the
ASD 532 must be serviced at least once a year by th
e manufacturer or by qualified
personnel authorised and trained to do so by the manufacturer. If required (e.g. significant dirt hazard), the se
r-
vice interval is reduced to guarantee functional reliability. If filter boxes and/or filter units are used, the
service life
of the filter inserts play a role in the service interval. Depending on the level of dust and dirty in the object, filter
service may vary greatly. The optimum filter service life is to be determined on site on a case by case basis.
The operator is obligated to conclude a service agreement with the manufacturer or with an installer authorised by the manu-
facturer if the operator does not have the required service personnel trained by the manufacturer.
The statutory national directives (DIN VDE 0833-1, Cantonal Fire Insurance Union) governing maintenance must be observed.
Servicing, maintenance or inspection work on the ASD 532 may be necessary after an event (fire, fault).
If a detector housing has to be replaced due to a defect, the new ASD 532 is to undergo the same procedure as a first-time
commissioning (initial reset required). All the customer-specific configurations have to be carried out once again on the re-
placed ASD 532.
For maintenance work and function checks, observe the relevant information set out in Sec. 2.3 below.
2.2 Cleaning
Clean the detector housing with a non-aggressive cleaning agent (e.g. soap suds or similar).
Normally only the sampling holes need to be cleaned on the sampling pipe tube network. In applications where dirt is a major
issue, it may be necessary to clean inside the sampling pipe (blow out with compressed air or nitrogen). Only non-aggressive
cleaning agents may be used when cleaning the sampling pipe (e.g. soap and water or similar).
Warning
Aggressive cleaning agents (such as solvents, pure petrol or
other alcohol-
based agents) must not be used for
cleaning.

14 / 21 ASD 532, Maintenance, T 140 425 en
2.3 Maintenance checks and function checks
Notice
To avoid triggering fire incident controls, remote alerting and extinguishing areas when carrying out maintenance
work, it is
essential to block or switch off those systems beforehand.
For maintenance and function checks, carry out the following points:
1.
Block or switch off fire incident control and remote alerting on superordinate FACPs.
2.
Check that the supply voltage on the FACP is set in compliance with maintenance instructions for the control panel.
3.
Check that the sampling pipe inlet is correctly seated.
4.
Check the air outlet for any dirt or dirt and clean if necessary.
5.
If the
ASD 532 is used for equipment monitoring and plug-
in transitions from rigid to flexible pipe sections are in place,
check that the transitions are correctly seated (no leakage).
6.
Open the cover of the detector housing. Carry out the following measurements:
•Measure the operating voltage on terminal 1 (+), 2 (-) target value = 17.6 to 27.6 VDC.
•
Readout sampling pipe airflow value in switch setting Vand compare with commissioning protocol. If there is a d
e-
viation of more than half the set sensitivity (see examples and ), check the sampling pipe as follows:
- An increase in the value (more than 100%) tends to indicate pipe breakage 
check the sampling pipe for
leaks (junctions, fittings, etc.)
- A decrease in the value (less than 100%) tends to indicate a pipe blockage c
heck the sampling pipe for pipe
blockage, clean as described under Item 9 or Item 10.

Set LS-Ü
sensitivity = ±20% (default); half of that = ±10%. The sampling pipe should therefore be checked if the
value is below 90% or above 110%.

Set LS-Ü sensitivity = ±50% (non-compliant with EN 54-
20), half of that = ±25%. The sampling pipe should therefore
be checked if the value is below 75% or above 125%.
7.
Switch off the ASD (pull terminal block 1/2 and if necessary 3/4 on the AMB
32). After disconnecting the ribbon cable
from the smoke sensor, carefully remove the sensor from the ASD.
8.
Use a soft, dry paintbrush to clean the inside of the smoke sensor chamber and the insect protection screen. Oil
-
free
compressed air or nitrogen can also be used for cleaning.
Warning
Do not use compressed air either to blow out or open the smoke sensor. Improper handling can affect the
response characteristics. Only the manufacturer is authorised to clean
dirty
smoke sensors. The smoke
sensors are monitored for dust and dirt; their states are displayed on the control unit. If required the smoke
sensor must be replaced.
After cleaning the smoke sensor chambers, re-insert the smoke sensor into the ASD.


Maintenance and service
ASD 532, Maintenance, T 140 425 en 15 / 21
Continuation:
9.
If it is necessary to clean the sampling pipe as indicated under
Item 6
, carry out the following measures (possibly also
according to Item 10):
•
Clean all sampling holes in the entire sampling pipe tube network. Tobacco pipe cleaners can be used for this pu
r-
pose.
•
If the sampling holes are not accessible, the entire sampling pipe tube network can be blown o
ut from the detector
housing using oil-
free compressed air or nitrogen. This is done via the manual ball valve or from the loosened
screw-junction piece (pipe connection) of the last accessory part in the direction of the sampling pipe network.
Warning
Blowing out from inside the smoke sensor chamber (through the fan) can damage the fan and is therefore
not permitted.
•
Open the accessory parts (water retaining box, filter-
box/filter unit, detector boxes) where fitted, and clean with a
soft dry paintbrush. Oil-
free compressed air or nitrogen can also be used for cleaning. Replace the filter cartridge in
the filter-box or filter unit. Close all the accessory parts again after cleaning.
•After cleaning the sampling pipe, re-connect it correctly to the ASD 532.
10.
In applications where dirt is a major issue, it may be necessary to clean the air
-
flow sensor. For this purpose (see
Sec.
2.4.3) take it out of the holder and clean with a soft, dry brush Caution
: Do not clean or touch the sensor
surface with your fingers.
Then re-insert the air-flow sensor as indicated in Sec. 2.4.3 
make sure it is correctly
seated inside the holder.
11.
Switch the ASD back on again and wait until the fan has reached its optimal speed (at least 2 min).
12.
Check fault triggering, alarm
release and correct alarm transmission to the FACP. Log the completed tests in the co
m-
missioning protocol.
13.
Read out the air
-flow values Vonce again. If the values set out under Item 6
are still outside the tolerance range, the
airflow monitoring will have to be readjusted (initial reset as described in Sec. “Commissioning”, T 140 421).
Danger
A new initial reset is not usually necessary after cleaning work on the sampling holes (cleaning restores the
commissioning state). If an initial reset is necessary nonetheless after the work set out under
Item 13
, it
may
only
be carried out once it has been ensured that all possible measures for cleaning the sampling pipe
have been carried out (incl. a new filter cartridge).
If an initial reset is carried out with blocked sampling holes, there is the danger that insufficient air samples
or no air samples will be aspirated and hence the ASD 532 can no longer trigger an alarm.
14.
If maintenance or repair work was carried out on the
ASD 532
(including the sampling pipe) as a result of servicing
check, a new initial reset may be necessary.
15.
All measurements and tests carried out are to be entered and signed for in the commissioning protocol. The completed
commissioning protocol is to be stored with the ASD. If required, a copy can be made and stored in the system dossier.
16.
After completion of the servicing check, close the detector housing once again.

2.4 Replacing units
Warning
Defective units such as the AMB
32, smoke sensor, airflow sensor and fan may can only be replaced in the de-
energised state (with terminal block 1/2 and possibly 3/4 unplugged from the AMB 32).
2.4.1 Replacing the smoke sensor
The smoke sensor must be replaced if defective or if there is a dirt message.
To replace the smoke sensor proceed according to Sec. Fehler! Verweisquelle konnte nicht gefunden werden.. It is impor-
tant to ensure that the new smoke sensor has the same alarm sensitivity range as the old one (SSD 532-1, -2, -3).
2.4.2 Replacing the aspirating fan unit
To replace the AFU 32 aspirating fan unit, the AMB 32 main board must be removed. To do so, carefully unplug all the internal

2.4.4 Replacing the AMB 32 Main Board
To replace the AMB 32 Main Board, unplug all the plug-in terminals with installation wires. Likewise, all internal cable connec-
tions (ribbon cable connectors) must also carefully be unplugged. Once the 5 fastening screws of the AMB 32 have been re-
moved using a Torx T10 screwdriver, the AMB 32 can be replaced. To install the new AMB 32, proceed in the reverse se-
quence.
Warning
When connecting the new AMB
32, take note of the correct assignment of the terminals and ribbon cable connec-
tors.
After replacing the AMB
32 it is imperative to carry out a new initial reset. Likewise, all customer-specific configu-
rations and pro
ject-specific settings from the “ASD PipeFlow”

Notice

Power consumption at maximum permitted voltage drop in the electrical installation (decisive value for calcu-
lating the conductor cross-section).

May cause the protective circuit to trigger immediately in the case of power supplies with overload protective
circuits (primarily in devices with no emergency power supply and output current of < 1.5 A).

Lower or higher temperature ranges are also possible subject to consultation with the manufacturer. The
manufacturer must be consulted if the device is used in the condensation range.
