I     General

Conventional Reflective Beam Detector (hereinafter called the detector) is a non-addressable 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.
