GST Beam Detector Conventional Reflective Beam Sensor Infrared Linear Smoke Detector C-9105R

Conventional Reflective Beam Detector (hereinafter called the detector) is a nonaddressable

reflective infrared beam smoke detector, which must be used together with

a reflector. The number of reflector(s) to be used (one or four) depends on the

distance from the detector.

With excellent built-in microprocessor, the detector has strong ability of analysis and

judgment. The detector can automatically carry out system adjustment, compensation

of variation of ambient data, and judgment of fire and fault through fixed algorithm, and

indicate these states by LED and signal output terminals. With new and reasonable

design, attractive appearance, flexible adjustment and alignment method it’s easy to

install and adjust. The sensitivity of the detector can be set through

hand held programmer in field, decreasing the demand for cleanliness of

field conditions, and enlarging application areas. The 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.

II 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. It’s 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 detector’s optical pathway is designed with strong anti-interference ability.

(10) SMT processing technology.

(11) Attractive and decent appearance.

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.
