Point type smoke fire detector
.
Introduction
Point type smoke fire detector is a photoelectric smoke detector developed using the principle of infrared scattering. The detector adopts modern technology and uses a microprocessor chip and non-volatile memory inside. It has powerful processing functions and accurate and reliable alarms. The smoke sensing parameter simulation quantity collection and processing, and the internal intelligent model criteria make up for the shortcomings of the traditional alarm mechanism. The microprocessor enables the detector to compensate for environmental changes through dynamic zero adjustment and differential correction technology.

.
Wiring and installation
Wiring requirements: The insulation resistance between lines and between lines and the ground is greater than 1, and the resistance of a single line of the detection bus loop is less than 1.
The two detectors are connected in parallel.
The bus loop of this system adopts a two-wire system, regardless of polarity. There is a conductor piece on the detector base with wiring terminals. When wiring, crimp the two bus lines of a certain circuit to the terminals of the detector base.
After the base is firmly installed, connect the bottom of the detector Align the base and rotate it clockwise to install the detector on the base.
The detector should be encoded with an electronic encoder before installation.
