Each device connected to an addressable system has it’s own unique address.
When a fire is detected the devices address is identified by the panel,
pinpointing the exact location of the fire.
With a conventional system there is no way of pinpointing the exact location of
the device that has been activated by a fire, only the general zone.
For example if you have a three storey building each floor may be wired as a
zone, so in the event of a fire you would only be alerted that the fire was on
a particular floor, not the exact location or room. This could slow down the
extinguishing of any fire causing a greater risk to loss of life and damage.
Addressable systems are wired in a continuous loop rather than radial circuits
used for conventional systems. This means if the cable was to be severed on
an addressable system, signals can still be transmitted to devices from either
end of the loop.
Although conventional fire alarm system cost less to purchase, they are
generally more expensive to install.
This is due to each zone for detectors and call points having to be wired, on a
radial circuit back to the panel.
This benefit of an addressable system is that all devices can be connected to
the same continuous loop, reducing cabling and time.
Addressable fire panels have large benefits over conventional, due to the ability
to continually monitor each of the installed devices individually.
The panel can determine whether each device is functioning correctly and
also ascertain the amount of heat or smoke that the device is currently
sensing. This technology allows the panel to make ‘intelligent’ decisions as to
the appropriate action to take based on the information it receives from the
individual sensors. This prevent the occurrence of false alarms which can be
costly to a business.
