About Sound Levels
To choose an alarm or speaker that’s loud enough, first determine the decibel (dB) rating of background noise.

Fire Alarm Horns with Strobe Light
In addition to loud beeps, these horns use flashing lights to warn you to evacuate during a fire. Connect them to your fire detection system, and a signal from your control panel will set them off. They help you comply with NFPA 72 standards for fire alarm systems.
All horns must be mounted to an outlet box: use an existing box in your facility, add an outlet box (sold separately), or choose a horn that includes an outlet box.
Low-frequency horns are better at waking sleepers than standard horns. They’re also more likely to reach individuals with hearing impairments.
Horns rated NEMA 3R are sealed to protect the wiring from dust, rain, and temperature swings. NEMA 4X-rated horns come mounted in a sealed outlet box. A gasket protects them from dust, heavy rain, temperature swings, and washdowns.
Horns with fire letter plates have legible text regardless of how you mount them. They have removable plates with text on both sides—one vertical, the other horizontal.
Use sync modules (sold separately) to make lights in the same area flash in unison.
