Klaxon SLM-0001 Master Blaster 127dB 230V Industrial Alarm Siren Yellow

The Klaxon Master Blaster SLM-0001 is a high-output motor-driven siren designed for use as a supplementary security alarm sounder in commercial, industrial, and high-risk environments. The unit operates from a 230V AC mains supply and produces a powerful audible alarm with sound pressure levels up to 127 dB, making it suitable for areas where a strong audible warning is required to deter intrusion or alert personnel. Activation is achieved through a 12V DC trigger relay, allowing integration with standard intruder alarm control panels and security signalling systems. The siren includes an internal activation relay and is continuously rated, allowing it to operate reliably in demanding installations. The Master Blaster is designed for surface mounting and is supplied with a separate mounting bracket to simplify installation and positioning. The device is pre-wired with a one-metre cable, enabling straightforward electrical connection during system installation. Constructed with a durable housing and suitable for indoor or outdoor use, the unit operates across a wide temperature range from -30°C to +45°C. With its high acoustic output and simple integration with alarm control equipment, the SLM-0001 is commonly used in warehouses, factories, plant rooms, and other industrial sites requiring a high-volume audible alarm signal.
