FIRERAY Heater Keeps Optical Beam Smoke Detectors Clear of Condensation
F
IRERAY optical beam smoke detectors provide wide area smoke detection when it is impractical to use traditional point-type detectors. They are also ideal for large indoor spaces with high ceilings, such as warehouses, sports arenas, factories or shopping malls. There are two general types of detector: projected, which utilise two detector heads; and reflective, which have one detector head and a reflector (prism). With the onset of autumn, lower temperatures can cause condensation to form on detector lenses and reflective prisms. This obscures the lens and prism, reducing the amount of infrared (IR) light reaching the detector. This has a similar effect to smoke and can lead to unwanted false alarms. To combat this issue, Fire Fighting Enterprises (FFE) has developed a new range of anti-condensation heaters for its FIRERAY range of optical beam smoke detectors and reflective prisms. The detector heater circulates a current of warm air over the lens, raising its ambient temperature by up to 10°C and maintaining the lens at an
incrementally higher temperature than the surrounding air. This dramatically reduces the likelihood of condensation forming on the lens which, in turn, reduces the potential for false alarms. The prism heater is an ultra-slim heating pad which is fixed behind the mounting plate. As with the detector heater, it maintains the temperature of the prism above that of the surrounding air, preventing condensation from occurring and reducing false alarms. As well as being an ideal solution to the problem of seasonal cold weather, the heaters could also be used year-round on detectors and prisms located in temperature- controlled cold storage areas. Heaters are available for use with the FIRERAY 3000, FIRERAY
New guide simplifies smoke ventilation selection
F
ire and safety specialist Be Safe Direct has launched a new guide, providing details of its range of natural and mechanical smoke ventilation systems and the benefits they can offer to various building types.
Created in response to growing demand for technical and regulatory information, the intuitive guide simplifies the process of selecting the right system for a number of applications, based on Approved Document B (ADB) Fire Safety Regulations. Detailing the fire safety needs for a range of building types, the document provides system suggestions for everything from lobbied single stair residential buildings to larger developments and car parking areas. For instance, Be Safe Direct’s ADB unlobbied stair smoke venting system is tailored for small, single stair residential buildings with no lobby

protection, and which have no more than two apartments per floor complete with protected halls. By taking this building design focused approach with its new guide, Be Safe Direct provides contractors with the reassurance of Building Regulation-Approved venting performance and reliability, at a highly competitive price. In addition to complete packages that provide ‘out of the box’ protection, the guide also details the Firesmart™ Control System, sold exclusively through Be Safe Direct. An intelligent, addressable control system, Firesmart™ has the ability to integrate several fire systems into a single control. Assessing the status of fire sprinklers, smoke detection, dampers, roof vents, fans and smoke ventilation and other systems, the control can streamline the monitoring of a building’s fire safety systems, allowing the quick
identification of issues, providing vital information for building managers, engineers and fire services alike. Samantha Riley at Be Safe Direct said: “Selecting the right smoke venting system is crucial for any project. By providing customers with the information needed to make an informed decision, our new guide can offer peace of mind for contractors, ensuring that their building meets fire safety standards while providing excellent value for money.” To order a copy of Be Safe Direct’s new guide call 0845 604 5653 or email
