  • JTY-GD-930KE point-type photoelectric smoke detector (Detector hereunder) is a two-wire switch-type smoke-sensing detector. As a non-polar two-wire connection is adopted in the detector, it is compatible in conventional switch-type alarm control systems and monitoring alarm systems. The detector can also be connected with intelligent bus fire alarm control systems via the interface module. The detector monitors smoke concentration in the workplace in real time. While monitoring, the red indicator blinks and the working current is low. When the work site smoke concentration has exceeded the preset alarm threshold, the alarm detectors and the red indicator remain on, while the loop current is increased. The detector’s alarm signal can be locked and is displayed by changes in the loop current. The alarm can only be reset by the instant power disconnection.


  • The detector is applicable in places where fire might generate volume smoke, i.e. in industrial and civil buildings such as in the restaurant, hotel, teaching building, office building, computer room, archives and stack room.
