This audible module is part of the Harmony XVB7 range, featuring Ø 70mm modular tower lights designed for easy customer assembly. This 2-tone buzzer is designed as an audible unit that connects to a base and various light modules to form a complete tower light. The XVB7C9S audible module is powered by 24V ACDC. Its sound pattern is continuous or intermittent, and its sound acoustic level is adjustable from 88dB to 102dB. Featuring a simple and modular design, this unit allows for easy installation with a base unit and light modules to create a complete tower light. This buzzer, ranging from 88dB to 102dB, along with the 360° omnidirectional sound, ensures clear alerts for critical machine statuses, even from a distance. It is impact-resistant, dust-resistant, water-resistant, and vibration-resistant thanks to its IP66, making it ideal for operation in harsh environments. Made from dark grey polycarbonate, it weighs 80g. The Harmony XVB7 modular tower lights are visual or audible signaling units used for indicating, throughout 360°, the various states of a machine or installation. This product complies with UL 60947-5-1, IEC 60947-5-1, and CSA C22.2 No 60947-5-1 standards. It features CE marking and holds cULus, CCC, RCM, and UKCA certifications. Light modules and base modules can be assembled to make a complete tower light. To simplify mounting, fixing plates, tubes, and brackets are available for separate purchase. Harmony XVB7 offers a wide range of voltage selection and flexible mounting options with visual and audible functions. The Harmony XVB7 range features a sleek design incorporating energy-efficient LEDs to maximize brightness while minimizing energy consumption.
