Addressing and Fire Alarm

When most of us hear that a building has a fire alarm system, we usually assume that it has a control panel like the one shown in photo 1 and that it is at or near the main entrance. From this location, the alarm system can be tested, silenced, reset, or programmed as needed. If the system uses digital addressable initiating devices, the panel will not only tell us which part of the building has the fire alarm, it will also tell us which pull station, smoke detector, heat detector, flame detector, flow switch, or tamper switch activated the alarm and where in the building it is located.
