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.
