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.
With the installation of a eXtended Line Module XLM 35 the ASD 532 aspirating smoke detector can be ideally connected to
the fire alarm systems SecuriFire (SecuriLine eXtended) and Integral (X-Line) via the addressable loop. Control operations and
changes to the ASD device configuration can be carried out directly from the FACP (in preparation). For this purpose the
FACP user software “SecuriFire Studio” and “Integral Application Center” are used to start the “ASD Config” configuration
software for access to the ASDs; the configuration software is then used to make changes to the ASD 532.
A further installation option is the RIM 36 relay interface module. This module enables the availability of all three pre-signal
levels as well as the states “smoke sensor dirty” and “LS-Ü pipe blockage” as relay contacts. The relays are also freely pro-
grammable via the “ASD Config” configuration software.
The SIM 35 Serial Interface Module is for networking multiple ASD 532 aspirating smoke detectors via RS485 bus. Using the
“ASD Config” configuration software, all ASD 532 units present in the network can be visualised and operated from a PC. The
master module in the ASD network is the SMM 535, by means of which a PC is connected.
Notice
The normative alarm transmission of the
ASD 532
to the superordinate centre does not take place via the ASD
network. For that purpose the
“Alarm” / “Fault”
relays in the ASD or the SecuriFire / Integral addressable loop are
to be used from the XLM 35.
The present technical description contains all information essential for trouble-free operation. For obvious reasons only those
details specific to individual countries and companies or special applications can be discussed if they are of general interest.

1.2 Uses and applications
Thanks to the detection method, air sampling by means of a sampling pipe tube network and the good properties of the prod-
uct under extreme ambient conditions, the ASD 532 aspirating smoke detector is used wherever problems can be expected
owing to poorly accessible areas to be monitored or latent disturbance variables during operation such that optimal protection
cannot be guaranteed with conventional point detectors. This includes:
•Space surveillance:
EDP rooms, ultra-clean rooms, warehouses, hollow floors, protection of cultural assets, transformer stations, prison cells,
etc.
•Equipment monitoring:
EDP systems, electrical distributors, switch cabinets, etc.
The ASD 532 can also be deployed in areas where normally conventional point detectors are used. Local regulations and pro-
visions must be observed from case to case.
The response behaviour of the ASD 532 has been tested in compliance with EN 54-20, Class A, B and C.
When control-unit-specific alarm transmitters, line monitoring elements etc. are used, the ASD 532 can be connected via its
potential-free change-over contacts to all common fire alarm systems virtually without restrictions.

1.5 Smoke sensors used
Danger
Only those smoke sensors in the device approval and in the list below may be used in the
ASD 532 aspirating
smoke detector. The use of third-party detectors voids the ASD 532 approval issued by the manufacturer.
Smoke sensors of the following type can be fitted in the ASD 532 (see also Sec. 4.9 and 6.6.4):
•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 response sensitivity of the concerned smoke sensor can be adjusted within the above specified range. Depending on the
application in accordance with EN 54-20, Class A, B or C, the value is specified via AMB 32 (pre-defined switch positions as
described in Sec. 4.4.4 to 4.4.4.3) or based on planning specifications using the ASD PipeFlow calculation software via the
ASD Config configuration software (see Sec. 7.2.1). The selection of the smoke sensor type with the respective range of sensi-
tivity is based on the information in Sec. 4.4.4.3 or “ASD PipeFlow”.
1.6 Hardware / firmware
The hardware is considered to comprise the complete detector housing and all the units belonging to the ASD 532 aspirating
smoke detector such as sampling pipe and mounting material.
The firmware is located on the Flash PROM in the ASD 532. An EEPROM is fitted for storing and saving system-specific pa-
rameters.
Danger
The
ASD 532 is to be operated only with the appropriate original firmware from the manufacturer.
Any unauthorised intervention in the firmware or the use of non
-
original firmware may result in malfunction and/or
in damage to the device. Furthermore, all guarantee and warranty rights with respect to the manufacturer of the
ASD 532 will become null and void as a result.
© Copyright by Securiton
All ASD 532 firmware is subject to the manufacturer’
s copyright. Any unauthorised intervention in the firmware, misuse,
copying or unauthorised trade with the firmware represents a breach of copyright and will be subject to legal proceedings.
Notice
A version change or extension of the
ASD 532
firmware does not imply a right to an upgrade or new release for
existing ASD 532 systems.
ASD532 Operating Manual

Function
18 / 121
2 Function
2.1 General operating principle
In the sampling pipe tube network, the fan generates a vacuum which results in fresh air continuously reaching the detector
housing via the sampling pipes. In this way the smoke sensor is constantly supplied with new air samples from the monitored
area. Should the smoke concentration exceed the permissible value, the ASD 532 triggers an alarm. The alarm is indicated
visually on the ASD 532 and can be transmitted via a potential-free change-over contact to a superordinate fire alarm control
panel.
The operational reliability of the aspirating smoke detector depends on the functional reliability of the smoke sensors and on
the constant air supply to the system. A fan failure, blockage of the sampling holes or pipe breakage must be communicated to
the fire alarm control panel in the form of a fault signal. This condition is satisfied by the airflow monitoring of the ASD 532.

2.2.1 Power supply
The operating voltage of the ASD 532 is +14 to +30 VDC. On the AMB 32 Main Board, 5 VDC of the operating voltage is di-
verted for internal voltage use.
The operating voltage is monitored on the AMB 32 for undervoltage. If the operating voltage falls below 13 VDC (+0 /
–0.3 VDC), the ASD 532 triggers an undervoltage fault.

2.2.2 Fan control
The physical and electrical properties of a fan cause a brief power surge when it is switched on and starts up, which in turn af-
fects the conductor dimensioning and the total power consumption of the fire alarm system.
A specially designed circuit therefore ensures that the fan cannot exceed a specific maximum power consumption in its start-
up phase. When the ASD 532 is switched on, the computer-controlled fan speed starts up slowly. After the fan has been pow-
ered up, the speed is kept constant.
Any blocking of the fan is detected by evaluating the motor speed. If the specified threshold is undershot, the fan supply is
switched off and a fault is signalled.
Depending on the size of the system and/or environment, the fan can be operated at different speeds (by means of the
“ASD Config” configuration software). This is useful primarily in critical areas (long pipes) to increase the transport speed in the
sampling pipe tube network (high speed) or to reduce the noise level in cases where the noise level produced by the fan is a
disturbance (low speed). The following fan speed levels can be selected:
Level
Speed
(rpm)
Effect
I
5250
Low transport speed / low noise level
II
6900
Normal transport speed / reduced noise level
III
9300
High transport speed / normal noise level
Notice
•
The fan speed levels can be changed only with the “ASD Config” configuration software.
•
For applications and commissioning without “ASD Config” configuration software, Level II must always set.
•
If the fan speed is changed (by using the “ASD PipeFlow”
calculation software), ensure that the maximum
permissible transport time according to EN 54-20 is not exceeded.
•
After the fan speed has been changed, it is imperative
that a new initial reset is carried out (observe waiting
time of at least 2 min).
2.2.3 Microcontroller
The entire program and switching sequence is controlled by a microcontroller. The firmware is stored on a Flash PROM. Sys-
tem-specific configurations are stored in an EEPROM.
The program is monitored by the internal watchdog of the microcontroller. In the event of a failure of the microcontroller circuit,
an emergency fault is triggered. This is signalled on the device by the steady lit Fault LED. The “Fault” relay switches.
