Global suppliers of fire detection test tunnels. Designed and manufactured in the UK


The AW technology detector test tunnels are the result of over 25 years of cutting edge designing and innovation. We have a great deal of experience designing fire detectors and alarms, putting us in a unique position to understand the needs of our clients and to supply the best possible products and support.

The smoke and heat test tunnels are designed for accurate testing of smoke and heat fire detectors. It is very important that fire detectors are tested during all stages of design, production and approval. They need to be sensitive enough to reliably detect fires which may present a risk to life, but not so sensitive that they raise false alarms, creating a ‘boy-who-cried-wolf’ scenario.

    1000 Tunnels

    The 1000 Series Compact Fire Detector Test Tunnels are based on the same technology as the 2000 Series. They are, however, smaller, bench-top designs with control electronics integrated into the structure of the tunnel. The 1000 series test tunnels are ideally suited to performance testing to EN54-7 and EN54-5 for factory production control, but can also be used in test and R&D laboratories.

  • 2000 Series

    2000 Series

    2000 series laboratory fire detector test tunnels are full size, floor-standing pieces of laboratory equipment. They are mainly intended for type approval testing to EN14604, EN54-7 and EN54-5, but are also ideal for fire detector R&D. The duct size permits the capability (with optional accessories) to carry out the high airspeed (gusting) type test for ionisation smoke detectors, and the high luminance (dazzle) type test for optical smoke detectors.

  • 3000 Series

    3000 Series

    The 3000 series optical detector calibration tunnels are designed for calibrating optical smoke detectors and smoke alarms in production. They are based on the 1000 series tunnels with an additional 1m long calibration section fitted. The tunnels can be maintained at a constant aerosol concentration for calibration, and are controlled by an optical scatter smoke sensor. The main section of the 3000 series tunnels is the same as the 1000 series, so can still be used for R&D and batch sensitivity testing as required.

    Carbon Monoxide 9000 Series

    Carbon monoxide alarms are becoming increasing important as awareness of the dangers of this gas become better known. Companies are developing and manufacturing carbon monoxide alarms, and test laboratories need to be able to test to EN50291-1.
