A range of modular stacking (click-together) beacon lamps with high environmental protection to IP65 standard. These products are ideally suited to internal or external multi-status signalling applications. This modular approach enables stacks to be constructed from any combination of module types and eases the task of design and maintenance engineers, system integrators and stockist/ distributors. The comprehensive range builds from a common base/terminal module and offers choice of visual indicator modules including LED (Rotating, Pulsed and Static), Xenon Strobe, Filament Lamp (Pulsed and Static), together with audible sounders (Mono-Tone, Pulse-Tone and Chime-Tone) and extender/separator modules. All external parts are moulded from engineering-grade, UV-stabilised polycarbonate for enhanced durability. To complement the range, Wall Mounting Brackets, Pole Mounts, Cast Aluminium Bases with Threaded M20 Entries, Compression Glands and AC to DC Converter Modules (UC-RECT) are also available. These devices are totally modular and can be used as single indicators or multi-stacked up to 6 modules high.
