Buying Guide

Siren loudness and dB rating

Choose alarms with clearly listed decibel ratings (e.g., 110 dB) so the signal is audible over ambient industrial noise and meets site safety needs

Mounting and installation type

Decide between surface-mounted units and wire-free/magnetic sensor installations based on door type, access points, and whether permanent wiring is practical

Durable housing and materials

Look for polycarbonate or other rugged housings and industrial-grade finishes for resistance to impact, dust, and routine facility use

Adjustable modes and features

Prioritize alarms offering adjustable modes (volume, chimes, strobe options) or multifunction settings to tailor alerts to different zones or shift patterns

Power source and battery considerations

Check whether units are battery-powered or require wiring; battery-powered options simplify retrofit installs but need a maintenance plan for replacements
