Conventional Fire Alarm Reflective gst Infrared Beam Smoke Detector
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 ± 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 , 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
4.9.3 structural characteristics , installation and wiring
The structure and shape of the detector and reflector installation
option to install and JTY-HM-GST102 type beam smoke detector fire
the same .
On-site installation , you need to 24V DC power cord ( non-polar )
, connected to the detector terminals D1, D2; terminals K21, K22
fault passive output normally open contacts , terminals K11, K12
was no fire source output normally open contact ; reflector without
wiring. Terminals shown in Figure 1 - 31.
Figure 1 - 31
Wiring requirements : Connecting K11, K12, K21, K22 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.
