Audible/visual signaling devices are safety warning systems that are triggered by dangerous safety malfunctions, such as a fire or burglary. The personal alarm speakers emit coded audio blasts during an emergency. A horn strobe releases a loud, piercing sound, while triggering a bright strobe light. We have many strobe and flashing lights options, plus other audible signaling devices from top brand names. In addition to system sensor horn strobe signaling devices, Zoro also carries tower lights and stopper covers and alarm guards to help protect security and fire alarms from vandalism.
