A typical fire alarm system in a commercial structure is designed to transmit an alarm both locally to occupants of the building and also to a remote monitoring station (typically your alarm provider). The alarm monitoring company then contacts the local emergency services dispatching center (911) for fire department response.

Like any other complex mechanical and computerized system, errors can happen. False alarms being transmitted resulting in a fire department response are common. In fact, these are the vast majority of fire department responses to commercial buildings, especially after hours. Typically, a single fire company will respond to evaluate the situation. If it is a false alarm, then the fire company will attempt to aid in finding the problem and helping you to get your system back online. Note that this is the responsibility of the building’s owner, manager, or occupant and the fire department only attempts to assist as a public service. If the responding fire company determines that there is an actual fire emergency, then they will call for additional backup and support and begin whatever actions are necessary to mitigate the emergency.

It is also possible for an alarm system to sound in and around the building itself but not to get transmitted to the alarm monitoring company. This can happen for any of number of reasons including mechanical or computer failure; radio, cellular, or phone line failure (depending on the type of service you use); or even human error or intervention. It is also possible for your buildings alarm system to fail completely although not likely.

Because of these possibilities, if there is an actual emergency, it is important for building occupants to establish contact with emergency services by dialing 911. If there is an actual emergency, your phone call can confirm this and get the total response force on scene much quicker. You can also give a heads up to the responders about any special circumstances like missing personnel, hazardous materials on site, injured people, etc. Please note that this phone call to 911 is important even if your alarm system is sounding and seems to be reacting appropriately.

On the other hand, if your alarm sounds and you are positive that there is no emergency, (for example: someone accidentally pulls an alarm lever or dust from cleaning sets off the detector) then you should contact your alarm company immediately. They can verify your lack of emergency and cancel the fire department before they arrive on scene. Not only does this keep precious emergency services resources available for real emergencies but it can also save you money. Per city ordinance, a fee can be assessed for false automatic alarms after a certain number have been reached in a year.
