Heat Alarm And Detector Test Tunnel - Color: Green

Equipment Function:
The heat alarm & detector test tunnel is used to test directional dependence, static response temperature, response times test for fire alarm and detector. The equipment meets the requirements of GB4716, EN 54-5, BS 5446-2, and ISO standards. The standard test tunnel is composed of a tunnel, heater, chiller, temperature control system, computer, etc. According to the requirements of standard specifications and parameters, we use fast-response thermocouples and an advanced PID controller to attain the heating rate of 0.2 A C/min, 1 A C/min, 3A C/min, 5A C/min, 10A C/min, 20A C/min, and 30A C/min as standard required. The maximum temperature is up to 160A C. During the test, the temperature will be controlled at +/- 2A C. The specially developed Zomtest heat test tunnel software can automatically control the test process, record the temperature curve, and record the alarm response time.
