About Smoke Detector:
1. Independent smoke detector, without wiring, using battery power.
2. Bus smoke detection: there are four metal terminals on the base, which can be connected to two points on the opposite corner of Zhi when wiring. Most of the smoke sensing wiring has no distinction between positive and negative poles, so it can be connected at will. However, it is better to unify the same connection method in a set of system. If the smoke detector wiring is divided into positive and negative poles, please refer to the instructions.
3. Multi line smoke detector (traditional smoke detector) is also a two-wire connection method. Take Jiawei smoke detector yt102 as an example: terminals 4 and 3 of the detector are power input terminals (polarity is not distinguished when wiring), and terminal 2 and terminal 3 are short connected inside the detector.
4. Relay smoke detection (relay signal output /), 4-wire connection: take dg311 as an example: connect the power line to the base terminal 3 and terminal 4, and the relay passive contact output line is connected to the base terminal 1 and terminal 2. However, the smoke detection system is a complex system, which requires professional personnel and professional knowledge to correctly install. It can not only rely on the knowledge to obtain the bit as the basis of work. For safety, it is better to ask professional staff to install.Smoke Detector suppliers
