Smoke Detector Test Tunnel - Color: Green

Equipment Function:
The smoke heat detector test tunnel was designed for sensitivity tests of smoke alarms/detectors according to GB 20517, GB4715, EN 14604, EN 54-7, and ISO standards. It consists of a test tunnel, aerosol generator, obscuration sensor, heat element, controller, and computer. The obscuration meter is made of high-quality imported parts to ensure precision and stable readings. The ZomTest Smoke Test Tunnel Software in English was designed by our software experts specifically to meet the standard test requirements.

When the wind speed is set at 0.2 m/s, the fluctuation range is less than A A A A 0.02 m/s
When the wind speed is set at 1 m/s, the fluctuation range is less than A A A A 0.1 m/s
High-temperature test function of smoke fire alarm:
Room temperature ~55 A A A A A A A A C, temperature control accuracy A A A A 1 A A A A C
Dry heat sensitivity test can be carried out in the smoke box
Standards can be selected by software, and the program can automatically control to the corresponding temperature, meeting the different requirements of European and national standards
Dazzling test device: Removable dazzling test device, software on/off automatic control

Constant smoke control function:

The smoke box is equipped with a constant smoke control function, which can set the constant smoke concentration and automatically control the smoke to be kept within the range of A A A A 0.003 dB/m
Maximum temperature: 55 A A A A C

Computer:

Includes industrial control computer and display
Industrial control computer processor performance: i3-12100
Memory: 8GB
Hard disk: 256GB SSD or above
Display: 23.8 inches
Test software: Chinese and English

Software function:

The equipment has the function of automatic sound detection
Start with one key, and the test process is automatically completed by the program
The process includes automatic wind speed switching, smoke rising control, temperature control, smoke detector directional rotation, smoke exhaust, light interference process, test data display, test result storage, etc.

Data storage and output:

It can automatically display the sensitivity value when recording an alarm
Each test record includes threshold value, smoke rising rate, temperature, test directions, serial number, and time
The record table can be exported to CSV format
The concentration or temperature curve data can be stored, and the concentration or temperature value of each point can be stored and exported to CSV format
