If you own a hotel, convenience store, restaurant, or some other commercial building, then at some point your business fire alarm has been activated whether intentionally or by accident. We all know that fire alarms are loud. They can even feel too loud. We also know that as soon as the alarm sounds, the police and fire department aren’t far behind.
But how does that entire process work? From the time the fire system’s alarm goes off to the time the police arrive, what occurs, and why is the timeline so important?
It’s important to recognize that a majority of fire damage occurs during night time hours when no one is onsite report it. According to the NFPA, fires after hours and on the weekends accounted for 19% of all fires and 31% of all property damage.
This figure alone makes the presence of fire detection with monitor service as part of an overall business security system incredibly significant. But how does it all work?
How Do Commercial Fire Alarm Systems Work?
You probably know why fire protection in your commercial property is necessary, so let’s take a look at how exactly the sequence of events goes. 0
1. The fire alarm is tripped.
When the sirens begin sounding, it means that a fire alarm device has been activated. It could be any number of life safety devices connected to your fire alarm system. Perhaps someone intentionally pulled a manual pull station (the little red box by most doors), or maybe a smoke detector was set off, even a heat detector.
2. An alarm signal is sent via the phone lines.
If you are set up for phone line monitoring, then a telephone line is connected to your alarm system. When a fire alarm system is tripped, as described above, the control panel sends the signal through the telephone line where it is then received by the 24-hr monitoring center.
3. Authorities are notified.
Once the monitoring center receives the alarm signal, they then call the authorities (police, fire, etc) to let them know that they have received an alarm at that address.
4. The customer is notified.
After the authorities have been notified, the monitoring center calls the location where the alarm originated to advise that they received the signal and police and fire have been dispatched.
Phone Line Monitoring
Above is the sequence of events that occur from the time a fire alarm is tripped to when the authorities arrive at the premise.
Step back to #2 above. If you have phone line monitoring, your panel sends signals through the phone line. Every commercial fire alarm system according to NFPA 72 must have a dedicated POTS (plain old telephone line) line to monitor it. Meaning, the phone line connected to the fire panel should be used SOLELY for monitoring purposes and it must be a POTS line.
If you do not have a POTS line, your security provider can help you get up to NFPA 72 code.
Phone line monitoring is not the only option.
Many customers are switching to cellular monitoring. Instead of needing to pay for a separate POTS line every month (which can get expensive), most fire alarms can be set up to transmit the alarm signals via the cellular towers instead of through the phone line.
The sequence of events laid out above remains the same, with the only difference being how the signal is sent to the monitoring center.
