Conventional Fire Alarm Systems
Fire alarm systems normally consist of a number of linked components including the fire alarm control panel, which is the centre of the system. The fire alarm control panel monitors detection devices and then activates notification devices when a fire is detected. These panels range in scale from a single zone to multiple zones, and even multiple buildings. Detection devices detect a fire and signal the fire alarm control panel. These can be triggered both manually (call points), as well as automatically in a response to heat, smoke or flame. When a signal is received from a detection device, the control panel will go into an alarm state.
Once a signal from a detection device has been received and the panel goes into an alarm state, the panel signals output devices that in turn, warn building occupants that there is an emergency situation. These are either audible or visual signalling devices, but the system may well also include output devices which shut down plant and BMS systems (such as HVAC systems) to prevent the spread of smoke; activate automatic suppression systems including pre-action sprinkler systems and more.
