4. Product installation
4.1 Select the appropriate installation location, generally installed on the ceiling in the center of the detector coverage area.
4.2 Connect the power line and signal line to the mounting base(mounting base〝1〞and〝2〞are no polarity input for power supply;〝3〞and〝4〞are alarm output contact)
4.3 Description of blue two digit dip switch
"2" corresponds to KT control switch
"1" corresponds to RST control switch
4.3.1 KT alarm output setting
When the KT switch "2" is pulled to the letter "on", the relay is normally closed
When the KT switch "2" is pulled to the letter "off", the relay is normally open
4.3.2 RST alarm mode
When RST switch "1" is pulled to the letter "on", it will reset automatically.
When RST switch "1" is pulled to the letter "off", the power is cut off and reset
4.4 Screw the mounting base to the ceiling
4.5 Align the locating convex point at the base end of the detector with the locating groove of the mounting base, and rotate clockwise to install the detector.
5. Notes
5.1 Pay attention to dust prevention. The dust cover must be removed after the project is officially put into use.
5.2 There shall be no shelter within 0.5m around the detector.
5.3 The horizontal distance between the detector and the air supply hole of the air conditioner shall not be less than 1.5m.
5.4 The horizontal distance between detector and wall, beam edge shall not be less than 0.5m.
5.5 The detector shall be installed in the middle of the inner walkway ceiling with a width of less than 3m. The installation spacing of the detector shall not exceed 15m, and the distance between the detector and the end wall shall not be greater than half of the installation spacing of the control detector.
5.6 The detector should be installed horizontally. For example, the inclination angle of inclined installation should not be greater than 45 degree.
5.7 The detector base shall be installed firmly and its wire connection must be reliable.
5.8 It is recommended to conduct a simulated fire test once half a year to test whether the detector works normally.
