ASD 535

The ASD 535 is the flagship model of the ASD detector range.

Overview

ASD 535

It can monitor an area of up to 5760 square metres.

Available as a single-sensor and two-sensor device, the detector analyses the airflow from one or two sampling pipes independently. The aspirating smoke detector thus reliably spots any deviation in the airflow and detects any breakages or blockages in the sampling pipes.

Up to 400 metres of sampling pipe with a maximum of 120 sampling holes can be connected to each smoke sensor. More than 400 Pa of aspirating underpressure generates the necessary power, which means the ASD 535 has one of the most powerful fans on the market.

Technical information

Frosty conditions? The ASD 535 won’t even sneeze. Hot conditions? No sweat – the ASD 535 carries on working without complaining. These robust aspirating smoke detectors can be deployed at temperatures ranging between – 30 °C and + 60 °C – retaining their full functionality at all times.

In deep-freeze applications, the evaluation unit is installed directly in the deep-freeze area and the sampling holes are heated automatically when needed to prevent them from freezing. Using the Config over Line function, you can carry out configuration and maintenance comfortably on the fire alarm control panel – having to personally access zones with extremely high or low temperatures is now a thing of the past. Further possibilities for accessing the aspirating smoke detector remotely are provided by RS-485 networking.

Dusty, steamy or dirty conditions? It makes no difference to the ASD 535. The extensive range of accessories includes various dust filters, water retaining boxes and other tools. The Autolearning function allows for automatic adaptation of the sensitivity according to the ambient conditions, which means the ASD 535 operates with optimum sensitivity at all times while also being protected against false alarms.

It is also immune to dust deposits thanks to its optimised aerodynamic measuring chamber. It cleans its sampling pipes and holes itself using the automatic blow-out device. The choice of sampling pipe material is determined by the individual requirements on site.

When it comes to the quality of the ASD 535, the aspirating smoke detector is designed for a very long service life. Although the ASD 535 is equipped with a high-performance fan, it is whisper-quiet. In fact, it’s one of the quietest aspirating smoke detectors on the market. It stands out by virtue of its extremely low noise levels (32 dBA), making it compliant with ISO standard 11690-1 for the design of low-noise workplaces containing machinery.
