GST Conventional fire alarm reflective infrared beam smoke detector/ beam smoke sensor

Description

1 Features

JTY-HF-GST**2 type beam smoke detector fire reflective type linear non-coding sense infrared beam smoke detector . Detectors must be supporting the use of reflectors , but requires the use of a reflector or four different decisions based on the distance between the two installed . Detector has the following characteristics :

( 1 ) The transmitter , receiver into one, easy to install, easy to use, optical collimation is good ;

( 2 ) with automatic calibration function , ensure the completion of commissioning by a single person in a short , simple operation, easy ;

( 3 ) has a self- diagnostic function , the detector can monitor internal fault ;

( 4 ) with automatic compensation function, for a certain degree of dust contamination , and the position offset of the launch tube causes the received signal is reduced aging factor can be automatically compensated ;

( 5 ) Field set three levels of sensitivity for different levels of dust place ;

( 6 ) has a fire , failure of passive output contacts ;

( 7 ) to detect optical design clever , strong anti-jamming performance ;

( 8 ) sealed design with waterproof performance ;

( 9 ) patented product , patent No. ZL ********7.

4.9.2 The main technical indicators

( 1 ) Power supply voltage : DC*5V ~ DC*8V

( 2 ) Supply Current:

Debugging current ≤ *0mA

Monitor current ≤ *2mA

Alarm current ≤ *2mA

( 3 ) the sensitivity level

A : 1.3 ± 0.3dB

Two : 1.7 ± 0.3dB

Three : 2.3 ± 0.3dB

( 4 ) Indicator :

Commissioning Status: green and yellow lights lit in a particular way or shiny

Normal monitoring state : red LED flashes periodically

Fire Status: Steady red light , yellow light goes out

Fault Status : yellow indicator light

All optical path is blocked : first reported the fault detector and light yellow light , *0s after the probe and reported to the fire and lit the red light , yellow light goes out

( 5 ) Protection area:

Detectors maximum protection area *4 × **0 = ***0m2, maximum width of *4m

( 6 ) Use of the environment :

Temperature : **0  C ~ **5  C

Relative humidity ≤ *5%, non-condensing

( 7 ) Dimensions:

Length : **6mm Width : *5mm Thickness : *5mm

4.9.3 structural characteristics , installation and wiring

The structure and shape of the detector and reflector installation option to install and JTY-HM-GST**2 type beam smoke detector fire the same .

On-site installation , you need to *4V DC power cord ( non-polar ) , connected to the detector terminals D1, D2; terminals K*1, K*2 fault passive output normally open contacts , terminals K*1, K*2 was no fire source output normally open contact ; reflector without wiring. Terminals shown in Figure 1 - *1.

Figure 1 - *1

Wiring requirements : Connecting K*1, K*2, K*1, K*2 twisted pair signal lines using fire-retardant , cross-sectional area ≥ 1.0mm2; power lines D1, D2 BV flame retardant cable, cross-sectional area ≥ 1.5mm2.
