Gst Conventional Reflective Beam Smoke Detector For Fire Alarm System

1 Features
JTY-HF-GST102 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 033580537.

4.9.2 The main technical indicators

( 1 ) Power supply voltage : DC15V ~ DC28V
( 2 ) Supply Current:

Debugging current: 20mA
Monitor current: 12mA
Alarm current:22mA

( 3 ) the sensitivity level

A: 1.3 A 0.3dB
Two: 1.7A 0.3dB
Three: 2.3A 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 , 20s after the probe and reported to the fire and lit the red light, yellow light goes out.

( 5 ) Protection area:
Detectors maximum protection area 14-100 = 1400m2, maximum width of 14m

( 6 ) Use of the environment :
Temperature : -10 C ~ +55 C

Relative humidity 95%, non-condensing

( 7 ) Dimensions:
Length : 206mm Width : 95mm Thickness : 95mm
