91405255

Overview

The Werma 91405255 is a continuous tone alarm bell from the 914 series, designed for audible signaling. It operates on a 24V DC supply and delivers a sound level of 98dB at 24V. The unit features a steel construction with a gray finish, measuring 167mm in diameter and 76mm in height. It provides IP66 protection against dust and water jets. Electrical connections are made via screw terminals, and it includes tension relief conforming to VDE standards.

Feature Summary

• Produces a continuous tone for clear audible alerts
• Constructed from durable steel material
• Includes integrated tension relief mechanism

Applications

• Wall-mounted industrial alarm systems
• High-noise environment signaling
• Safety alert units requiring high decibel output

Procurement Notes

Verify that the application voltage matches the specified 24V DC requirement. Confirm that the installation location supports wall mounting and can accommodate the physical dimensions of 167mm diameter. Ensure the environment meets the IP66 rating requirements for dust and water exposure. Check that screw terminal wiring methods are compatible with the existing control infrastructure.

Selection Notes

Select this model when a high-intensity audible signal is required in harsh environments. The 98dB output makes it suitable for areas with significant background noise. The steel housing offers robustness compared to plastic alternatives. Consider the wall-mount constraint and ensure adequate space for the 167mm diameter footprint during system design.

Part Context

This component belongs to the Werma 914 series of audible signaling devices. The series focuses on robust, industrial-grade alarms built for demanding conditions. The 91405255 variant specifically utilizes a steel body and continuous tone generation, distinguishing it from piezoelectric or electronic siren variants within the broader product line.
