JTY-GD-3002B photoelectric smoke detector

JTY-GD-3002B point photoelectric smoke detector is a Yun 'an brand product produced by Shanghai Songjiang Fan Fei Electronics Co., Ltd. (formerly Shanghai Songjiang Electronic Instrument Factory). This spot smoke detector is an upgraded version of JTY-GD-300 1A and JTY-GD-3002A, which combines the advantages of these two smoke detectors.

JTY-GD-3002B point photoelectric smoke detector is the same as JTY-GD-300 1A and JTY-GD-3002B in appearance, both of which are ivory probes, φ 102× 43, and there are some similarities in technical parameters:

(1) alarm current: ≤2mA

(2) Wiring requirements: BV line ≥1.0mm2.

(3) service environment: temperature-10℃ ~+50℃

Relative humidity ≤ 95% (40℃ 2℃, -2℃)

(4) Installation requirements: Avoid air supply outlets of air conditioners and places with dust, water mist, steam and gasoline.

(5) Features: A. Early alarm and high sensitivity;

B. With black smoke alarm function

JTY-GD-3002B also has some differences on the technical basis of the original JTY-GD-300 1A and JTY-GD-3002A:

(1) monitoring current: < 350μA a.

(2) Features: A. Double bus system, nonpolarity

B. Software address coding

Residual current type electrical fire monitoring detector

It is used to monitor the insulation status of low-voltage distribution lines and electrical equipment on line, and is installed at the first and second levels of distribution line classification protection pair. When the insulation of power distribution or electrical equipment is aging, which leads to leakage and reaches the alarm threshold, the device sends an alarm signal and transmits it to YA6000 electrical fire monitoring equipment or fire alarm controller.

1. product features: dual bus system (S+, S-)

Action current

Use dip switch (20ma-999ma) to set the leakage alarm threshold on the detector;

When it is normal, the indicator light flashes and the alarm is always on.

2. Overall dimension and color: 200×80×25 red.
