Heat detector 4 wire 9-35V HD504 – Complete, socket included

Heat detector 4 wire 9-35V with an effective solution for fire protection.

The HD504 heat detector offers a combination detection of temperature rise and fixed temperature, 57 degrees, with coaxial cable, which is perfect for both domestic and commercial applications.

Heat detector 4 wire 9-35V detector option consists of an externally mounted thermistor with a specially designed hood that protects the thermistor while allowing for maximum airflow.

The thermistor measures the temperature of the incoming air and transmits a signal representing the temperature to the control IC.

If the temperature reaches or exceeds the threshold value, the detector is triggered. The status LED lights up red and the alarm's signal is activated.

Magnetic switch self-test:

Connect the detector to the circuit and place a magnet near the detector. If the detector is working normally, the red indicator light is on.

Test:

Simulate an environment to test the detector: place the detector in a chamber with a thermometer and use a heating device to raise the air temperature in the chamber.

When the temperature reaches the threshold value, the detector's LED lights continuously in red, and the alarm signal is activated.

Note:

1. The detector cannot be installed in places exposed to direct sunlight or heat.
2. It is recommended to install the detector near a smoke detector.
3. Make sure the base is securely attached and all wire connections are correct.
4. Test the detector every quarter.

Installation:

1. Connect the wires to the mounting base.
2. Choose a suitable location (normally mounted in the middle of the ceiling). Attach the mounting base, then insert the detector into the base and twist to secure.
