The smoke alarm test tunnels are suitable for controlling the quality of optical detectors, ionization detectors and heat detectors. Our test tunnels are constructed of stainless steel sheet, are double walled and heat insulated. The inner lining has a cross section of 0.4 x 0.4 m and the outer lining is 0.5 x 0.5 m. The overall length of the channel is approximately 4.20 m, the channel (without frame) is 2.10 m high.

The tunnels are modular and are assembled from replaceable channel segments and elbows. It is thus possible to extend every channel at a later date, e.g. by adding a cooling segment with a pneumatic telescopic refrigeration system.
