IV Structure and Operation Principle
1. Appearance of the detector is shown in Fig. 1.
2. Operation principle
The detector uses infrared scattering technology; the smoke density can be detected. The detector
receives very weak infrared light under normal smokeless condition. If smoke particles enter the chamber,
the received light signal will increase by scattering. When smoke density reaches a pre-set level, the detector
will alarm out. In order to reduce interference and power consumption, the emitting circuit works in pulse
mode to prolong the life of IR LED. It is cooperating with TC addressable fire alarm control panels to build
a fire detection system.
Mounting and Wiring
1. Mounting
Installation of the detector is shown in Fig. 2.
2. Base of the detector is shown in Fig. 3. There are 2 conductor pieces with terminals on the base.
Detector's loop should be respectively connected with two terminals (polarity-insensitive).After the base
is fixed firmly, rotate the bottom of detector and base clockwise, and then the detector will be fitted to
the base.
. 3.Recommended Wiring
1.0mm2 or above fire cable, subject to local codes.
4. Warning: Before installing the detector, please cut off power and make sure all bases fixed firmly.
VI Testing
1. The detector must be tested after installation and periodical maintenance.
2. Testing content:
1). Registration: After confirming the installation and wiring is correct, register devices to the fire alarm
control panel, and check whether the numbers of installed detectors and registered detectors are
consistent.
2). Fire simulation test: After registration, choose one detector arbitrarily, and fit it to meet fire
conditions to check whether the detector generates fire normally.
3). After testing, reset the detector. Notify the proper authorities that the system returns to normal state.
4). Clean the failure detector in the test according to Maintenance, and test it again. If it is still fail to
pass, please return it to repair.
3. Warning: Before testing, please ensure that the detector has been installed correctly and powered up.
