Product Description

• Brand Name: ANSORL
• Infrared Reflective Beam Smoke Detector AS-BSD-08
  ANSORL Conventional Reflective Beam Detector AS-BSD-08 (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 its 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.
   

  Products 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. Power Voltage: 15VDC-28VDC

  2. Power Current:  Commission current20mA, Standby current12mA, Alarm current22mA

  3. Fire Alarm and Fault Contact Output:

      Fire Alarm Relay: Contact capacity 28V/2A, which is normally open in normal state 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

  15. Mounting Hole Spacing: Spacing for embedding: 158mm
       Spacings for surface mounting: 79mm€96mm

   

  Structure and Operation Principle:

  The detector and reflector are placed oppositely.

  The detector includes emitting part and receiving part.

  Infrared beam of certain intensity sent out from the emitting part is reflected by the right-angle prisms of the reflector, and then received by the receiving part of the detector.  

  The receiving part simultaneously collects and amplifies the returned infrared beam, analyzes and   judges the collected signals through its microprocessor.  

  When the detector is in normal monitoring state, the intensity of infrared beam received by the receiving part is steady at a certain level.

  When smoke particles enter the detecting area, the intensity of infrared light received by the receiving part falls owing to light scattering.

  When the smoke particles reach a certain density, and the intensity of infrared light received by the receiving part is reduced below the preset threshold value, the detector alarms fire, illuminates Red LED, and closes passive fire output contact.

  Operation principle is shown in pictures.
