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.


They are supplied in two main sections, but are not difficult to assemble on site. The PC base unit is pre-configured, and most of the wiring is already in place on the tunnel. Clear instructions (and support) are provided, making it possible to start testing without one of our specialists having to be present.


• Capable of carrying out full range of tunnel tests to EN standards
• Ideal for test laboratories and fire detector R&D
• Ability to test to EN54-7, EN54-29, EN14604 and EN54-5
• Comprehensive technical support
• Additional training from AW Technology available
• Air flow deflector funnel available for high airspeed tests
• Full size dazzle rig available for testing optical detectors

The following variants are available in the 2000 series:

 

2200 Smoke Detector Test Tunnel: Designed for testing to EN54-7 and EN14604 over an operating temperature range from room temperature to 55°C.

2400 Combined Smoke / Heat Detector Test Tunnel: This is designed for testing to EN54-7 and EN14604 from room temperature to 55°C, and to EN54-5 with a starting temperature range from 25°C to 80°C. It is capable of carrying out testing for grades A1 to C to EN54-5, including tests from the maximum application temperature for grade C.

2700 Heat Detector Test Tunnel with Cooling: designed for testing to EN54-5 with a starting temperature range from 5°C to 55°C; capable of carrying out testing for grades A1 to C to EN54-5, including tests for suffix R detectors and tests from the maximum application temperature (80°C) for grade C.

2800 Combined Smoke / Heat Detector Test Tunnel with Cooling: Designed for testing to EN54-7 and EN14604 from 0°C to 550°C, and to EN54-5 with a starting temperature range from 5°C to 55°C (as 2700).

The following additional options are available for the 2000 series:

2001 Spare hatch with fixed mounting plate for up to 6 detectors
2003 Hatch with rotating detector mount for directional dependence testing, or for tests at a selected orientation
2004 Spare rotating detector mount (for use with hatch 2003)
2006 Airspeed meter (‘anemometer’) with analogue output integrated with the software
2007 Interface and mount for MIC (standard reference for ionisation detectors)
2008 Optical scatter smoke sensor and software extension to enable simultaneous optical smoke and heat ramp testing (for use with 2800).
2009 Dazzle test rig for high luminance type testing of optical smoke detectors
2010 Airflow deflector funnel for false alarm testing on ionisation detectors to EN54-7 at 5ms-1 and 10ms-1
2011 Hatch and motorised rotating detector mount with software control

 

The overall mechanical parameters are as follows.

Overall size of tunnel: 3.15m long * 0.86m wide * 1.60m high
Internal cross section of duct: 470mm wide by 370mm high
Working volume cross section for smoke detectors: 350mm * 250mm
Working volume cross section for heat detectors: 350mm * 100mm
Extract via 150mm diameter flexible duct (requires a back draught shutter)
Size of cooling unit supplied with 2700 and 2800: 0.9m long * 0.78m wide * 1.15m high.
