Alarm Placement Guidelines

To ensure your alarm system provides adequate coverage, follow these guidelines when placing alarm devices:

Put at least one visual alarm in each room and any other general usage areas.
  • Put at least one visual alarm in each room and any other general usage areas (guest restrooms, meeting rooms) which may be occupied by those with hearing impairments. You may need more than one alarm per room for those that exceed the manufacturer's spacing requirements. For example, if your alarm is rated for 50 feet, install alarms so they are evenly spaced with no more then 50 feet between devices.
  • Mount visual and audible devices 80 inches above the highest floor level within the space or six inches below the ceiling, whichever is lower.
  • Make sure manually activated devices for use in conjunction with alarms are unobstructed, conspicuous, and readily accessible.
  • Make available an emergency communications system such as a public address system, telephone, portable radio unit, or other means to notify employees of the emergency and to contact local law enforcement, the fire department, and others.
