Heat Detectors PD-928HT instruction
The heat detectors are designed to detect ambient temperature, When ambient temperature reaches preset value or the temperature flare up to rise, the LEDs light, and it output signal immediately triggering connected unit to work Be suitable for the industrial and civil building where there is explosive and combustible gas.
SPECIFICATION of Heat Detector
Detecting temperature method:
rate of rise and fixed temperature
Power source: DC12V~DC24V
Static current :<60μA
Working humidity:10~90% RH
Installing method: ceiling installation
After installing and switching on power, the
heat detectors are in operation state. When it detects
that the ambient temperature is higher than
preset alarm value or the temperature flare up
to rise, the LEDs light and the unit output signal
CHARACTERISTICS of heat detectors
*Explosionproof function, elegant shell, easy to installation.
* Non-pollution, high safety.
*The heat detectors have good stabilization, false alarm is little, and it not influenced by weather’s changing.
* In the circumstance that there probably are smokeless fire and there are quantities of powder dust.
* In the circumstance there are smog and steam resorting.
* Kithen, boiler house, tea stove house, electrical machine house and drying workshop.
* Indoor carbarn, smoking room etc.
* Other halls and public place where smoke detector is not fit to install.
① Terminal 5 connect" +"
② Terminal 2 connect "–"
③ Terminal 6 and 3(4) - relay output terminal
1. Press and hold the base and turn it counterclockwise, take down base.
2. According to the number mark on base and connection-wire diagram, connect wire to number corresponding screw with gasket.
3. Fix the base on the selected position.
4. Cover Heat Detector body: make the short line on the base aim at the long line on alarm body and turn clockwise until the long line on base aim at the long line on alarm body.
