ASD 532

The ASD 532 is used for reliable monitoring of small and medium-sized areas and premises.


ASD 532

It has the same technical specifications as the ASD 535, but with just one sampling pipe and a more compact fan. Anyone familiar with the ASD 535 will find added monitoring using the ASD 532 a breeze.

Configuration and maintenance of the detector are made in the same simple way.

Technical information

Aesthetically, the ASD 532 is very subtle and discreet – just like all devices in the ASD range. Once installed in hollow spaces, the sampling pipes are completely invisible, while the flush-mounted sampling holes are often imperceptible.

The installation is carried out with the highest possible level of adaptation to the surroundings in question. The sampling pipe can be laid out asymmetrically, which means it blends seamlessly into the structure of the building. This eliminates the need for long sampling pipes and thus reduces costs.

Key Features

  • ASD 532 - Aspirating smoke detector for 1 SSD 532 smoke sensor without smoke level indicator
  • ASD 532-3 - Smoke sensor 0.02-10%/m alarm sensitivity (0.00087 dB/m)

For medium-sized premises:

  • Compact Design
  • Permissable Temperature Range: - 20.c to +60.c
  • Maximum sampling pipe length: 120 m
  • Ethernet or RS-485 networking
  • Approvals: VdS, UL*, FM*


The ASD 532 is ideal for property and space surveillance thanks to its excellent response behaviour. Typical applications include:

Room surveillance

  • Museums, galleries, theatres, cinemas
  • Cultural artefact collections, historical buildings
  • Informatics and computer centres
  • Telecommunication centres
  • Laboratory and Research Centres
  • Electronic Measuring Rooms
  • Transformer Rooms
  • Clean Rooms
  • Refridgerated Warehouses

Property surveillance

  • Telecommunication facilities
  • High and low-voltage distribution cabinets
  • Display cases
  • IT installations
  • CNC control systems

Invisible surveillance

  • Protection of cultral assets
  • Prison cells
