GST Reflective Beam Detector 

 Optical Beam Smoke Reflective Beam Detector with Relay Output

General Descriptions

Conventional Reflective Beam Detector (hereinafter called the detector) is a non-addressable reflective infrared beam smoke detector is   applicable   to   historical   buildings, warehouses,  large  storages,  shopping  malls,  leisure  centers,  exhibition  halls,  hotel lobbies, printing houses, clothing factories, museums and prisons etc, as well as places where slight smoke particles exist.

 

Features

(1)   Wide operating voltage range, big monitoring areas.

(2)   Combination of the emitting and receiving part makes mounting easy and optical pathway accurate.

(3)   Built-in microprocessor enables intelligent judgment of fire alarm and fault.

(4)   The detector can calibrate automatically, which ensures that one person complete adjustment in short time. Its also convenient to operate.

(5)   Self-diagnosis function can monitor the inner fault.

(6)   Automatic  compensation  for  factors  weakening  received  signals,  such  as  dust contamination, positional excursion and ageing transmitter.

(7)   It has passive output contacts for fire alarm and fault.

(8)   Two sensitivity levels can be set in field.

(9)   The detectors optical pathway is designed with strong anti-interference ability.

(10) SMT processing technology.

(11) Attractive and decent appearance.

 

Technical Specifications

 

(1)  PowerVoltage:15VDC-28VDC

 (2)  Power Current: Commissioncurrent›20mAStandbycurrent›12mA Alarm current›22mA

  (3)  FireAlarm and Fault Contact Output FireAlarmRelay:Contactcapacity28V/2A,whichisnormallyopeninnormalstate  and closed in fire alarm state.
Fault Relay: Contact capacity 28V/2A, which is normally open in normal state and closed in fault state.

 

 (4)   Angle of Adjusting: -6°-+6°
(5)   Dependency Angle of Optical Pathway Orientation: 0.5¢
(6)   Sensitivity Level:
Level 1: High sensitivity. Level 2: Medium sensitivity.
(7)   Indication of Detector State:

Commission: Green LED and Yellow LED are lit or flash in a certain way. See details in Section VI Commission.
Normal monitoring state: Red LED flashes periodically.
Fire: Red LED constantly illuminates, and Yellow LED turns off. Fire alarm should be cleared through powering up again.
Fault:  Yellow  LED  constantly  illuminates.  The  detector  clears  the  fault  signal automatically if the condition causing the fault disappears.
Optical pathway obscured totally: the detector first gives fault signal and turns on Yellow LED. 20s later, it alarms fire, illuminates Red LED and turns off Yellow LED. Note: In this case, it does not mean there is a fire. After the obscuration
is removed, the detector clears fault signal automatically. Fire signal has to be cleared by powering up the detector again.

(8)   Operating Environment: Temperature: -10°C-+50°C
Relative Humidity 95%, non condensing
(9)   Monitoring Area:  aximum monitoring area: 14*100=1400m2
Maximum width: 14m
(10) Length of Optical Pathway: 8m-100m
(11) Protection Level:
Under common environment, ingress protection rating is IP20.
Under  special  environment,  ingress  protection  rating  is  IP66  through  glue-seal treatment.
(12) Dimension: length: 206mm width: 95mm thickness: 95mm
(13) Material and Color of Enclosure: ABS, gray
(14) Weight: 450g
