Page 6: What Is An Optical Beam Smoke Detector
FIRERAY PRODUCT GUIDE What is an Optical Beam Smoke Detector Definition An Optical Beam Smoke Detector comprises of a Transmitter, a Receiver and a Control Unit The Transmitter is an infrared light source that generates and projects a modulated infrared (invisible) light beam over an area to the Receiver. -
Page 7: Operation Principles
Optical Beam Smoke Detector sees light produced by the Transmitter in a normal condition. The Receiver is calibrated to a preset sensitivity level based on a percentage of total obscuration. AMPAC’s range of Optical Beam Smoke Detectors offers various sensitivity settings to choose from. -
Page 8: Optical Beam Smoke Detector Types
FIRERAY PRODUCT GUIDE Optical Beam Smoke Detector Types There are currently two types of Optical Beam Smoke Detectors. The Projected style and the Reflective style. 2.3.1 Projected The Transmitter and the Receiver are installed at each end of the area to be protected, up to 100 metres apart. -
Page 9: Application Of Projected And Reflected Optical Beam Smoke Detectors
FIRERAY PRODUCT GUIDE 2.3.3 Application of Projected and Reflected Optical Beam Smoke Detectors The Type of Optical Beam Smoke Detector used will be dictated by the installation and the environment conditions and constraints. Projected Optical Beam Smoke Detectors are less susceptible to stray reflection as reflections go back to the transmitter. -
Page 10: Where Is An Optical Beam Smoke Detector Used
FIRERAY PRODUCT GUIDE Where is an Optical Beam Smoke Detector Used Traditional Applications Optical Beam Smoke Detectors are used to provide “wide area” smoke detection. These are usually used in situations where it is either impractical, inappropriate or not cost effective (installation, wiring and maintenance) to use traditional point type detectors. -
Page 11: Specify An Optical Beam Smoke Detector
FIRERAY PRODUCT GUIDE Specify an Optical Beam Smoke Detector Standards The following guidelines are provided to give a general summary of common situations in which Optical Beam Smoke Detectors are used. There are many recognised National and International standards and Codes of Practise. Please refer to your local authority for your applicable standards and codes Coverage / Ceiling Height Optical Beam Smoke Detectors generally have an operating range of up to 100 metres. -
Page 12: Flat Ceiling
FIRERAY PRODUCT GUIDE Smoke layering, where smoke does not reach the ceiling level due to layers of static hot air, is overcome by mounting the Optical Beam Smoke Detector / Reflector at the recommended height below the ceiling of between 0.3 metres and 0.6 metres. This brings the infrared light beam below the heat layer and into the smoke layer. -
Page 13: Apex Ceiling - Peaked Type
FIRERAY PRODUCT GUIDE 4.3.3 Apex Ceiling – Peaked Type A ceiling or roof with a slope in excess of 4.5 degrees should be regarded as an APEX ceiling / roof. When Optical Beam Smoke Detectors are mounted in an APEX, the lateral coverage either side of the beam axis can be increased in relation to the angle (Ø) of the pitch, using the following formula: X = 7.5 + (7.5 x Ø/100) metres For example... -
Page 14: 4.3.4 Atrium
FIRERAY PRODUCT GUIDE 4.3.4 Atrium If the Optical Beam Smoke Detector is to be placed in an Atrium, or near glass / polished surfaces, the Receiver / Reflector should be offset from the central line of sight, and angled back to the Transmitter This can be either on the vertical or on the horizontal axis, or a combination of both. -
Page 15: Capability To Critical Enviroments
FIRERAY PRODUCT GUIDE Capability to Critical Enviroments 4.4.1 High Air Velocity High air movement does not have as great as an effect on Optical Beam Smoke Detectors as other detector types. An Optical Beam Smoke Detector’s sensing range can be long as a football field (maximum beam range is typically 100 metres). -
Page 16: Stratification
FIRERAY PRODUCT GUIDE 4.4.3 Stratification Stratification occurs when smoke is heated by smouldering of burning materials and becomes less dense than surrounding cooler air. The smoke rises until there is no longer a difference between the smoke and the surrounding air. Therefore, stratification may occur in areas where the air temperature may be elevated at the ceiling level, but especially where there is a lack of ventilation. - Page 17 FIRERAY PRODUCT GUIDE There is no sure way of identifying what condition will be present at the start of a fire. Any of the following detection schemes can provide for prompt detection regardless of the condition present at the time of fire initiation. Upward Optical Beam Smoke Detectors to Detect the Smoke Layer: The purpose of this approach is to quickly detect the development of a smoke layer at whatever temperature condition exists.

Page 18: Comparison With Point Type Detectors
FIRERAY PRODUCT GUIDE Comparison with Point Type Detectors 4.5.1 High Air Velocity Point Type Detector High Air Velocity may blow smoke out of the sensing chamber Optical Beam Smoke Detector High air movement does not have as great as effect on Optical Beam Smoke Detector’. An Optical Beam Smoke Detector’s sensing range can be typically as long as 100 metres. -
Page 19: Interface To A Fire Alarm Control Panel
FIRERAY PRODUCT GUIDE Interface to a Fire Alarm Control Panel 4.6.1 Conventional Optical Beam Smoke Detector Conventional Optical Beam Smoke Detectors are very versatile; they are compatible with any conventional control panel and by using them in conjunction with a suitable interface control module, they can be added to any intelligent system irrespective of the communication protocol between the Control Panel and Detectors 4.6.2... -
Page 20: Install An Optical Beam Smoke Detector
FIRERAY PRODUCT GUIDE Install an Optical Beam Smoke Detector Structure Optical Beam Smoke Detectors must be mounted on stable stationary surfaces for proper operation: to prevent movement and subsequent misalignment. A surface that moves, shifts, vibrates, or warps over time will cause false alarm or trouble conditions. Initial selection of a proper mounting surface will eliminate false alarm or nuisance signals In cases where only one stable mounting surface as defined above can be used, and Reflected Optical Beam Smoke Detector has been chosen, the Transceiver should be mounted to the stable... -
Page 21: Reflections And Obscuration
FIRERAY PRODUCT GUIDE Reflections and Obscuration Reflective objects too near the line of sight can reflect the infrared light beam from the Transmitter. There must be a permanent clear line of sight between the Transmitter and the Receiver / Reflector. If this occurs, the whole area may not be protected or movement of these reflective objects can cause false alarms. -
Page 22: Optical Cross Talk
FIRERAY PRODUCT GUIDE Optical Cross Talk Optical Beam Smoke Detectors should be positioned adequately to avoid the infrared light beam from other Optical Beam Smoke Detectors falling on the detector, either directly or indirectly. Mounting Receivers or Reflectors back to back creates a high possibility for infrared light overspill If a pair of Optical Beam Smoke Detectors is to be used to cover a “long jump”’... -
Page 23: Testing Procedures
FIRERAY PRODUCT GUIDE Testing Procedures After successful installation and alignment (see manufacturer’s specific alignment procedure), the Optical Beam Smoke Detector will require testing for both Fire and Trouble conditions 5.7.1 Smoke Test Tacking into account the sensitivity threshold set during installation, the Optical Beam Smoke Detector can be smoke tested by progressively obscuring approximately half of the receiver optics (for the projected type Optical Beam Detector) or half the Reflector (for the Reflected type) with non- reflective material... -
Page 24: Commision An Optical Beam Smoke Detector
FIRERAY PRODUCT GUIDE Commision an Optical Beam Smoke Detector Once Optical Beam Smoke Detectors are installed, as part of an automatic fire alarm system, it needs to be commissioned and set to work before it can be formally handed over to the purchaser. Commissioning is a process that involves thorough testing of the system. -
Page 25: Maintain An Optical Beam Smoke Detector
FIRERAY PRODUCT GUIDE Maintain an Optical Beam Smoke detector Before starting any maintenance on Optical Beam Smoke Detectors, the proper authorities need to be notified that the Optical Beam Smoke Detectors will be temporarily out of service. The zone or whole system managing the Optical Beam Smoke Detectors that are undergoing maintenance is isolated to prevent unwanted alarms and possible dispatch of fire services personnel. -
