Answer Posted / raj
There are several differences between conventional &
addressable fire alarm systems. These differences include;
Addressable fire alarm systems give information about
individual detectors, whereas conventional systems only give
information
about specific circuits (zones).
1.
Due to this, addressable systems allow a courtesy text label
to allow easy identification of any event. For instance
detector 1
may be given the label “Bedroom 1.
2.
Most addressable systems allow an early “pre-alarm” warning,
which allows the responsible person to investigate potential
alarms before the system activates it`s sirens
3.
Many addressable systems can alter the alarm threshold of
the detectors, in order to meet the needs of different
environments in
different areas of the system
4.
5. Addressable systems are usually wired in a loop.
Conventional systems are usually wired as radial circuits.
6. Addressable systems usually have a real time clock &
event log to record system events.
Larger addressable systems usually have the ability to use
sophisticated programming options to operate certain outputs
only
with specific events.
7.
Historically, addressable systems have tended to be
complicated to configure, and cost between 50% to 100% more
than a
conventional equivalent
