Manufacturers Product Description
The outdoor-use CS-154BS incorporates a wide-range horn, making it ideal for background music or paging announcements with high-quality sound. The use of a horn in combination with a cone speaker increases acoustic conversion efficiency, producing high output. A constant-directivity horn (90° horizontal) enables uniform and clear sound dispersion over a wide area. The CS-154BS has a resin enclosure that is lightweight, strong and resistant to impacts, as well as able to withstand outdoor installation weather conditions. Stainless-steel brackets and screws further protect against rust and corrosion. The speakers also comply with the IP65 Standard for dust- and waterproofing. Internal speaker parts feature a special weatherproofing treatment, while weatherproof polyurethane resin paint makes the enclosures extremely resistant to ultraviolet light. EN 54-24 and ISO7240-24 certified, the CS-154BS is authorized for use in fire detection systems. It is also in compliance with BS 5839-8: 2008 14.8.
