Whether you are upgrading your fire protection systems in your building or need to install new fire alarms, it is important to understand the different types of commercial fire alarms available. From the automatic alarm systems to the manual alarms, there are quite a few things you should know before blindly choosing a system. Let’s take a look at some fire alarm systems you could choose for your commercial spaces

There are two distinct types of fire alarms you can have in your commercial space. The first is an automatic fire alarm. When these alarms detect heat or smoke, they send an audio-visual alert throughout the building to alert the occupants of danger. The next type of fire alarm is a manual alarm. These fire alarms have pull stations stationed around your building. When a fire is seen or smelled by one of your employees, they simply pull the leveler and alert the occupants. Manual alarms come in a variety of designs and colors.
