Werma 444.300.75 LED Alarm Light Indicator, 24V, Yellow

The Werma 444.300.75 LED alarm light indicator is a professional-grade signaling device engineered for demanding industrial environments. This unit combines a high-visibility yellow LED double flash with a powerful multi-tone sounder, providing a comprehensive visual and audible warning system. Built to operate at 24V AC/DC, it ensures consistent performance in automated systems, control panels, and safety-critical infrastructure where reliable status monitoring is essential.

Advantages

This signaling device offers exceptional durability and versatility through its robust polycarbonate lens construction, which is designed to withstand harsh industrial conditions while maintaining optimal light diffusion. With a service life of up to 50,000 hours, it significantly reduces maintenance requirements and downtime. The integration of both visual and audible alerts in a single unit allows for flexible configuration, enabling users to trigger 32 different tones and manage sound output up to 120 dB to suit specific operational needs.

Suitable for

• Industrial automation and machinery status monitoring
• Safety-critical warning systems in manufacturing plants
• Control panel signaling
• Emergency notification in hazardous work zones

When it may not be suitable

This device is designed for 24V power systems and will not function correctly if connected to higher voltage mains without appropriate power conversion. It may also be less effective in extremely high-ambient-noise environments if the 120 dB output is insufficient for the specific site requirements.

Key specifications

• Operating voltage: 24V AC/DC
• Rated current: 0.26 A
• Light color: Yellow
• Sound output: Up to 120 dB
• Number of tones: 32
• Service life: 50,000 hours
• Lens material: Polycarbonate

How to use

Installation should be performed by qualified personnel in accordance with local electrical safety standards. The device is designed for surface mounting on control panels or machinery housings. Once mounted, connect the 24V power supply to the designated terminals. The multi-tone sounder and LED flash functions can be configured via the internal settings, allowing for independent triggering of the visual and audible components. External triggering for up to three specific tones can be set up during the initial wiring phase to match your system's logic.

What to consider before purchase

• Verify that your power supply provides a stable 24V AC/DC output.
• Ensure the mounting location allows for clear visibility and audible coverage.
• Check if the 120 dB sound level meets your facility's safety regulations.
• Confirm that the environmental conditions are compatible with the polycarbonate housing.

Usage recommendations: Regularly inspect the lens for dust or debris to maintain maximum light intensity and ensure that the electrical connections remain secure to prevent signal interruptions in critical safety applications.
