WERMA

WERMA buzzer alarms are available in multiple voltage ratings. Common options include 24V AC/DC and 115–230V AC. For example, the 28 mm diameter buzzer models 10700070 and 10701070 operate on 24V AC/DC, while models 10700060 and 10701060 operate on 115–230V AC. The 52 mm diameter models 10900075 and 10901075 also use 24V AC/DC. Power consumption for these buzzers is typically 0.25 W or 0.73 W depending on the model. When selecting a buzzer, confirm the available control voltage and the required sound output for the application.

WERMA tower light assemblies are used to provide visual and audible status indication on industrial machinery and automation systems. A two-tier assembly such as the 69932075 includes red and green light tiers plus an integrated sounder tier, operating at 24V AC/DC. These assemblies are commonly mounted on control panels, machine frames, or structural supports to signal machine states such as running, stopped, fault, or material shortage. The color-coded tiers allow operators to identify conditions from a distance. The integrated sounder adds an audible alert for conditions that require immediate attention. Selection depends on the number of states to indicate, voltage available, and mounting requirements.

Many WERMA signaling devices are rated for indoor and outdoor use. The product listings for the Multi-Tone Sounder 14015060, buzzer alarms 10700060, 10700070, 10701060, 10701070, 10900075, and 10901075 all specify indoor/outdoor suitability. This rating indicates the devices are designed to withstand environmental exposure typical of industrial outdoor installations, such as dust and moisture. However, specific IP ratings should be verified for each model if the application involves direct water spray, high-pressure washing, or extreme temperatures. For outdoor installations, consider additional protection or confirm the model's ingress protection rating with the manufacturer's datasheet.

Power consumption varies by model. The WERMA Multi-Tone Sounder 14015060 consumes 0.12 W. Buzzer alarms in the 28 mm and 52 mm ranges typically consume 0.25 W or 0.73 W. For example, models 10700060, 10700070, 10701060, 10701070, and 10901075 are rated at 0.73 W, while model 10900075 is rated at 0.25 W. These low power figures allow the devices to be driven directly from control outputs or relay contacts without significant load. When planning circuits, ensure the total load of all signaling devices does not exceed the output capacity of the controlling device.

Selection depends on the required sound output, adjustability, and mounting constraints. WERMA tone alarms, such as the Multi-Tone Sounder 14015060, typically offer multiple selectable tones and higher sound pressure levels, making them suitable for areas with higher ambient noise. Buzzer alarms, such as the 28 mm and 52 mm models, provide a single buzzer tone and are often more compact. Voltage compatibility is a key differentiator: tone alarms may operate on 115–230V AC, while buzzers are available in both 24V AC/DC and 115–230V AC. Consider the available control voltage, the need for tone adjustment, and the physical space for mounting.
