CONVENTIONAL HEAT' DETECTOR
AGNI-203
A G N I ’ C O N V E N T I O N A L H E AT
DETECTOR is a device with advanced
technology and feature that detects rate
of rise of temperature. It does not operate
without electrical power. The special
feature of this detector is dual
thermistors. One is sealed and the other
is exposed. In the event of fire, the
exposed thermistor reacts quickly to rate
of rise and fixed temperature. When a
specific temperature is reached, due to
variation of temperature in both the
thermistors, the detector automatically
switches over into alarm mode and
invokes the fire alarm.

INSTALLATION
AGNI Conventional Heat Detector are compatible with all type of Conventional Semi
Addressable andAddressable (using module) FireAlarm Control Panels.
The AGNI-205 Base made of ABS Plastic, is a conductive base. It has one way locking
mechanism with the detector. The flame class is V-0, The base is required to be fixed before
connecting cables and mounting of Detector.
Technical Specification:-
Operating Temperature (Environmental) : 10C + 50C
Relative Humidity : <95% No condensation
Height : 16mm
Diameter : 100mm
Colour : White
Material : ABS
?As the detector dose not operate without electrical power, it is advised to check regularly and
ensure that there is no interruption of power supply to the device.
?The detector should be stored within the recommended range and allowed to stabilize to
room temperature before applying power for successful operation.
?Installation of the device should be carried out as described in the installation sheet.
?Detector should be installed in compliance with Bs5389 Part 1 and En54.
?check the wiring and fix the base of the detector firm to the roof/wall.
?Fix the detector in the base by the mark-line and rotate the detector clockwise until it reaches
the locked position and ensure that it is tightly fixed to the base.
?Till completion of installation, do not remover the red plastic dust cover.
?Calibration sensitivity test per NFPA code is required to be carried out once the installation of
device is complete.
