The JTY-GD-CA3302 photoelectric smoke detector is designed to be super- thin with a patch technique and a two-wire and non-polarity system. It has a strong anti-interference capability and low power consumption. It can be used safely in many different situations.
The detector's chamber with a y-type labyrinth can detect effectively the smoke of a smolder fire and smoke given off at the start of a fire. The light-sensitive component can detect the light, as the light is scattered in the room after the smoke enters or fills the room. When the light strength attains to threshold of the fire alarm, the light (red) of the detector will be bright, and the alarm signal will be transmitted to the exported equipments. This information is included as a quick reference installation guide. To ensure proper operation, these devices shall be connected to the compatible JB-QB-W series of control panels only. For the further details about our control panel, please refer to the panel installation manual.
4 Installation and connecting 4.1 Installation The JTY-GD-CA3302 photoelectric smoke detector must only be used with its base together. First, the detector base is fixed on the joint box (the joint box was set in the ceiling beforehand); Second, the lines are connected according to the installation diagram; In the end, the detector is screwed tightly to the base.
