<Smoke alarm test tunnels, type EN 54>
Smoke alarm test tunnels, type EN 54
for controlling the quality of optical detectors, ionisation 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.
Our test tunnels are equipped with the following measuring instruments:
Thermometer, anemometer and extinction measuring device. They also come
with an aerosol generator with process control computer that regulates
the wind speed and temperature in the channel, generates the required
concentration and temperature ramps and automatically cleans and cools
the channel after each measurement.
An ionisation measuring instrument (MIC) is not installed as standard.
However, the corresponding clamp for installing an MIC is fitted.
