718 Fire Prevention Plans

To get the most from an alarm system, follow these guidelines when selecting devices:

Make sure the alarm sound and visual signal are as different from the background noise and light as possible.

Make sure the alarm sound is as different from the background noise and light as possible. Audible alarms should exceed the ambient noise level by at least six decibels. The light intensity for visual alarms should be at least 75 candela.

Use alarms with integrated audible and visual signals to accommodate the hearing and visually impaired, and for areas where a person may be working alone. This includes areas such as restrooms, storage areas, offices, and similar areas. (These devices are available for about the same cost as an audible or visual signal alone).

Avoid using strobe devices that flash at rates above five flashes per second (fps). Rates above five fps can trigger seizures in people with certain forms of epilepsy. When multiple devices are used, either synchronize or reduce their flash rate so that the combined rate does not exceed five fps.
