Greetings. Following up on Why Monitored Fire Equipment Works a couple of weeks ago, I’d like to share How Monitored Fired Equipment works.
By National Fire Code, all commercial and residential fire equipment designed to detect “particulates” uses either radiative chamber analysis, photo electric analysis or energy beams for large and possibly very dusty or dirty environments. The most used is photo electric. It does the most reliable and affordable detection. All three methods of detection result in the monitored circuit going CLOSED on detection. The alarm proceeds from that event. Fire equipment includes communicators (telephone line) or cellular based. Both are supervised to ensure that the equipment is self-testing and ready 100% of the time. Once an alarm happens, the communicator contacts the Central Station where the data is converted into an Alarm Event and Dispatched by Central Station Operators. Typically, the time from initial discovery to dispatch is measured in seconds. Data records are kept on location within the equipment, at the Central Station and at the Local 911 Center that broadcasts the alarm to waiting Fire Departments.
Knowing more about how the equipment and procedures operate makes clearer why losses are reduced or eliminated. In my first post we looked “back in time”, after a total loss, to learn if it could have been prevented or mitigated. Monitored Fire Systems are not only very effective, but they also come at such a small fraction of the risk value as to make them a “no brainer”.
Next time we’ll look at the Audible Response of Fire Alarm Systems.
