Heat Alarm,Detector Test Tunnel

EquipmentFunction：

The heatalarm & detector test tunnel is used to test directional dependence, staticresponse temperature, response times test for fire alarm and detector. Theequipment meets the requirements of GB4716, EN 54-5, BS 5446-2 and ISOstandards. The standard test tunnel is composed of tunnel, heater, Chiller,temperature control system, computer etc. According to the requirements ofstandard specifications and parameters, we use fast response thermocouples andadvanced PID controller to attain the heating rate of 0.2 ℃/min, 1 ℃/min, 3 ℃/min, 5 ℃/min,10 ℃/min, 20 ℃/min and 30 ℃/min as standard required. The maximum temperature is up to 160 ℃. During the test, the temperature will be controlled at + / - 2 ℃ . The specially developed Zomtest heat test tunnel software can automatically control the test process, record the temperature curve and record the alarm response time.
