When is a Fire Alarm System Required?
Most buildings contain some type of battery-operated smoke detector or fire alarm to protect occupants. While this may be adequate for a single-family dwelling or home workshop, commercial and multi-family residential properties are required by fire and building codes to have commercial fire alarm systems installed.
The professionals at Newport Network Solutions, Inc. can help you determine when a fire alarm system is required for your commercial property and the importance of proper installation and maintenance.
