Safeopedia explains Alarm System
The two most common types of alarm used in the workplace are audible alarms and visual alarms. An audible alarm may take the form of a bell, siren, horn, or voice announcement. A visual alarm may use a steady strobe or flash light.
In order to meet OSHA specifications, an employee alarm must be able to be heard and seen above ambient noise and light levels by all employees in the workplace. Employees who are not able to see or hear a standard alarm should be catered for by way of a tactile alarm.
According to NFPA72 National Fire Alarm Code, new systems are not permitted to use bells, horns, or sirens. They can only be in the form of temporal or voice signals.
