## Long description

The THORKILD LARSEN Masterbell is an electromechanical industrial bell designed for audible signaling in factories, warehouses, workshops and other industrial facilities. It operates at 24V DC and features a gray metal bell bowl with an external diameter of 154 mm, producing a measured sound pressure level of approximately 91–94 dB at 1 meter. The device is built for straightforward integration into alarm, shift-change and process notification systems where a clear, high-level acoustic signal is required.
Advantages
The Masterbell offers robust electromechanical construction that provides consistent acoustic output and long service life under industrial conditions. Its 24V DC drive is compatible with common industrial control panels and PLC outputs, enabling easy electrical integration. The compact bell diameter and metal bowl design deliver focused sound projection while minimizing enclosure footprint. Measured sound pressure of 91–94 dB at 1 m ensures audibility across noisy environments without complex amplification.
Suitable for
Alarm and warning systems in production halls and manufacturing plants
Shift change signaling in warehouses and large workshops
Process notifications and machine cycle alerts
Safety and evacuation indication where a distinct acoustic tone is needed
Key specifications
Operating voltage: 24V DC
Bowl material: metal (gray finish)
Bowl diameter: 154 mm (external)
Sound pressure level: approximately 91–94 dB measured at 1 m
Actuation: electromechanical striker mechanism
How to use
Mount the bell on a rigid surface using appropriate hardware to ensure secure attachment and optimal sound transmission. Connect the 24V DC supply and control wiring according to the facility’s electrical schematics, observing polarity and any protection devices such as fuses or circuit breakers. Test the unit after installation to confirm correct operation and verify the sound level at typical occupancy points. If used with external control equipment, configure the control outputs or relay contacts to energize the bell for the required signal duration and repetition pattern.
Usage recommendations
Install the bell away from large reflective surfaces or enclosed cavities that may distort sound; provide routine inspections to check mounting integrity and electrical connections; limit continuous duty cycles if the installation manual specifies intermittent operation to prevent accelerated wear of the striker mechanism.
