1 General
1.1 Purpose
The ASD 531 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 531 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 31 smoke sensor is used in the ASD 531. It has an alarm sensitivity range of 0.02%/m to 10%/m.
The ASD 531 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;
With the installation of a eXtended Line Module XLM 35 the ASD 531 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 531.
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 of the smoke sensor and the sampling pipe.
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 531 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 531 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 531 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 531 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 531 aspirating
smoke detector. The use of third-party detectors voids the ASD 531 approval issued by the manufacturer.
The ASD 531 is fitted with the SSD 31 smoke sensor by the manufacturer. It has an alarm sensitivity range of 0.02%/m to
10%/m.
The response sensitivity of the smoke sensor can be adjusted within the range specified above. The value is defined via the
AMB 31. This applies to applications with as well as without calculations using “ASD PipeFlow” (Sec. 4.3.1 and 4.3.2 respec-
tively).
1.6 Hardware / firmware
The hardware is considered to comprise the complete detector housing and all the units belonging to the ASD 531 aspirating
smoke detector such as sampling pipe and mounting material.
The firmware is located on the Flash PROM in the ASD 531. An EEPROM is fitted for storing and saving system-specific pa-
rameters.
Danger
The
ASD 531 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 531 will become null and void as a result.
© Copyright by Securiton
All ASD 531 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 531
firmware does not imply a right to an upgrade or new release for
existing ASD 531 systems.

18 / 105 ASD 531, Technical description, T 140 416 en
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 pipe. 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 531 triggers an alarm. The alarm is indicated
visually on the ASD 531 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 sensor 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 531.

2.2 Electrical functional principle
Fig. 2Block diagram
2.2.1 Power supply
The operating voltage of the ASD 531 is +14 to +30 VDC. On the AMB 31 Main Board, 5 VDC of the operating voltage is di-
verted for internal voltage use.
The operating voltage is monitored on the AMB 31 for undervoltage. If the operating voltage falls below 13 VDC (+0 /
–0.3 VDC), the ASD 531 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 531 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.
The ASD 531 aspirating smoke detector has a constant, specified fan speed. The speed is 5250 rpm.
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.
