False fire alarm signals are a problem to both business owners and fire services. Not only can they become costly in fees, they can also result in unneeded business disruption. Properly maintaining your fire alarm system helps reduce these nuisance alarms. There are some leading causes of these instances which can also be avoided.


Manual Pull Station Activation

Unfortunately, manual pull station activation in a non-emergency is most often caused by acts of mischief.  There may be a few things that you can do to prevent this from happening. First, figure out if the device located in an area where it’s prone to vandalism or being hit by equipment transported through the area. You might want to consider fitting a cover on it, and depending on the layout of the premises perhaps repositioning is possible.


Activation of Smoke Detectors

Activation of smoke detectors is a common cause of false fire alarms. They are often caused by cooking fumes, steam, airborne pollutants, insects, dust, and more. Having your system regularly inspected can help prevent these false alarms before they occur, as can ensuring properly protecting your equipment during renovations and construction. Incorrect usage of devices can also be a problem.  There are some areas which better suit a heat detector versus a smoke detector, so it’s important to ensure your fire protection is correct for your buildings’ purpose.


Aging Components/Systems

Most manufacturers recommend that various components be replaced at varying intervals. Aging systems can be behind false alarms when their components are beginning to fail. Engage with your fire protection maintenance partner to understand if your system is starting to have failures, and work with them to determine the best course of action to keep your system functioning as intended.
