Buying Guide

Siren loudness and decibel rating

Choose alarms with at least 100–110 dB for noisy industrial environments so the signal is audible through machinery and background noise

Sensor and trigger type

Decide between magnetic contact sensors for door-open detection or motion/pressure triggers depending on your door design and reset needs

Housing material and durability

Polycarbonate or other impact-resistant housings withstand industrial wear; check for weather and dust resistance if used in exposed locations

Adjustable modes and reset options

Alarms with multiple modes (chime, siren, timed alarms) and easy manual or automatic reset let you tailor behavior for different shifts and security policies

Power and installation

Consider battery-operated, wire-free units for retrofit installation and hardwired models for continuous reliability and fewer battery changes
