Fire Security Alarm Smoke Detector
Description
Where Should Smoke Alarms be Installed?
Smoke alarms should be installed on every level of the home, outside sleeping areas, and inside bedrooms
A smoke alarm should be installed and maintained according to the manufacturer`s instructions. When installing a smoke alarm, many factors influence where you will place the alarm, including how many are to be installed. Consider placing alarms along your escape path to assist in egress in limited-visibility
conditions. In general, you should place alarms in the center of a ceiling or, if you place them on a wall, they should be near the ceiling.
