Aspirating smoke detector ASD 535

Aspirating smoke detector ASD 535 consists of one or two independent aspiration pipes with one or several suction inlets as well as a metering box. The air of the rooms to be monitored is aspirated and accurately analysed in the metering box of the scattered light detector. If the detector samples smoke particles which exceed the defined threshold value, it will immediately trigger an alarm. This enables the fire brigade to fight the fire before it breaks out fully.

Line-type heat detectors

Line-type heat detectors are predominantly used in locations where, due to the aggressive and critical atmospheric conditions (e.g. high air humidity, extreme temperatures, outdoor areas, aggressive gases, dust pollution etc.), conventional fire detectors cannot be used, or where, due to the exceptionally large monitoring length or areas, a very large number of heat detectors would be required.

Linear smoke detector

Consists of a transmitter and receiver unit working in the infrared range. The detector is particularly reliable where there is a constantly changing ambient temperature or air humidity, is easy to set up and excels in particular due to its low power consumption. The intensity of the infrared rays is corrected automatically, and the sensitivity can be set to one of three levels.
