My Fire Alarm is in Trouble, Now What?

What you Need to Know!

Fire Alarm systems are the first line of defense when it comes to fire protection. these systems actively work to detect smoke, heat, or an activated fire suppression system. Once detected it sounds an alarm, activates horns and strobe lights, and notifies the Fire Department. Depending upon which systems are in place, smoke control goes into action, fire doors are closed, and air handling equipment is shut off. These systems help to allow you time to escape the building at the first sign of fire.

A fire alarm panel has a few different colored lights to indicate status in your building:


Green Light: Normal, power is on, and the fire alarm is operating accordingly.

Yellow Light (Supervisory): This indicates that a system within is not normal and needs immediate attention. Therefore, you may not need to contact the fire department. Call USAFP team for service.

Yellow Light (Trouble): The system itself has a problem that needs to be fixed. You may not need to contact the fire department.  Call USAFP team for service.

Yellow Light (Monitor): Indicate there could be a problem in the future. Call the USAFP team for service.

Red Light: Alarm has been triggered in a zone or device. As a result, building wide horns and strobes will activate and alert the fire department.
