Addressable Intelligent Heat Detector
Addressable point type spot heat detector intended to measure temperature level, wherever temperature monitoring required. This device primarily designed for automatic fire detection system. Fire is sign of abnormal temperature and sudden rise of temperature. Hence this abnormal condition is used for triggering fire warning system. This device measures the temperature level in protected area and analyses the level of temperature and verify with predetermined alarm level setting. When temperature level crosses the set level, it communicates to fire warning system control panel along with its ID. Alarm raised by the sensor, continuously interacts with control panel to update the real time temperature exists at reported location. If temperature level rises, action can be taken accordingly. Similarly if it gets reduced, action can be taken for normalcy by rescue staff.
TEMPERATURE LEVEL ALARM SETTINGS
Standard temperature level for alarm is set at factory. According to area of protection, this setting can be changed from control panel by the user.
SOFT ADDRESSING:
Based on the order, the address of the sensor is configured at the factory. If an alteration in the address is required, it can be changed from the control panel. No extra special tools are required.
REMOTE TESTING
The various functional validations manually from the remote control panel can be done for maintenance and troubleshooting. If the control panel is connected to the cloud, it can be accessed through the internet/mobile app.
DETACHABLE DETECTOR
A detector designed to be easily removed from its normal operating position for maintenance and servicing purposes.
INSECT MESH
The heat chamber vent is covered using anticorrosive metal mesh to prevent the entry of insects.
ENVIRONMENTAL TYPE TESTING
The detector environmental type tested, as per IS 11360, UL 264N with NABL India.
HEAT DETECTOR CALIBRATION
As per IS 2189/ NBC 2016 heat detector being a measuring instrument and the sensitivity is vulnerable to get reduced, hence periodical calibration is required. Our factory is located in Chennai, India. We undertake calibration services for our make sensors and certify them. The certificate is mandatory to be maintained for the government and third-party audits.

What is a heat detector and how does it work?
Heat detector is an instrument that measures its ambient temperature. It will raise an alarm by monitoring the rate of rise of heat in its surveillance.
Heat detector consists of a thermistor component that measures surrounding temperature. The resistance offered by the thermistor device decreases with increase in heat sensed by it, thereby increasing the values of voltage and current drawn by the circuit. Detector’s intelligence algorithm monitors the difference in voltage values at continuous intervals of time. The higher the difference in voltage, the higher the increase in heat.
In case of fire, the rise in temperature is rapid. Meaning, in less time the difference in temperature measured is very high. This parameter of rate of rise in heat is considered to raise an alarm confirming presence of fire.
Further, alarm is also raised when the live temperature exceeds the pre-set upper limit/threshold values of the detector.
This detector is much more effective than fixed temperature detectors and is also unharmed by dusty or smoky environments.
