1.Overview
JTY-GD-S832 photoelectric smoke fire detector adopts non-polar power input, which can detect the smoke generated during a fire and send an alarm signal in time. The detector adopts CPU control, which can intelligently judge the concentration of smoke produced during a fire.
When the detector is in the monitoring state, the red indicator light flashes and the working current is small; when the smoke concentration on site exceeds the set alarm threshold, the detector enters the alarm state, the red indicator light is always on, and the relay operates. The detector has a relay dry contact output, the alarm signal is given in the form of a change in the action of the relay contact, and has an alarm lock function. The alarm reset can only be realized by a short power off.
The detector has an automatic compensation function for dust accumulation, which can reduce the influence of dust on the sensitivity of the detector.
The detector is suitable for places where a large amount of smoke is generated when a fire occurs, but there is no smoke under normal circumstances, such as: restaurants, hotels, teaching buildings, office buildings, computer rooms, communication rooms, bookstores and archives and other industrial and civil buildings.
But it is not suitable for places with a large amount of dust and water mist;
Not suitable for places where steam and oil mist may be generated;
Not suitable for places where smoke remains under normal circumstances
