Fire Alarm Cable So Much More than Meets the Eye

Fire alarms, for you and many others, likely
connote a mid-day disruption at work, often
either a false alarm or a test of an emergency
system. They arent taken seriously. Standing out
in the parking lot, after youve filed out with
your coworkers, you grumble about the annoyance
as the alarm shrieks. You check your phone,
wondering when you can get back inside to finish
up the task at hand. You probably didnt think
about the alarm system, whats involved in the
execution, the need for it to work at any time at
the pull of a lever or the trace of smoke. Its a
system where testing is necessary, but delivering
during the real deal is when it really counts. 99
successful tests wont matter if it doesnt work
the one time the emergency is real.

There are two common types of fire alarm systems
conventional and addressable. Both system types
link devices, like smoke, flame, and heat
detectors, to a main control panel. Conventional
fire alarm systems are cheaper to buy but are
more expensive to install and are less reliable
overall. Theyve been around for a long time and
are present in many buildings across the United
States. Think of the red box with the white
handle. Each device connected to the main control
panel in a conventional system is run using its
own wire. The more devices, the more wire, the
more manpower to install. If a wire gets cut,
itll take the whole system down. With that being
said, conventional systems work well in smaller
locations where the setup is simpler.

Addressable fire alarm systems are more expensive
to purchase but are less expensive to install and
are more reliable in general. Every device on an
addressable system has its own address, and the
main control panel will tell you which address is
alarming when the system is going off. One wire
loop with both ends connected to the main control
panel links all devices on the system. If one end
of the loop is cut, signals from the other end
can still be sent. In addition to conventional
and addressable systems, you can find hybrids of
the two.

Regardless of the system chosen, the wiring,
which consists of Fire Alarm Cable, is typically
hardwired, unlike generic smoke detectors in your
home. This cabling is regulated by the National
Electrical Code. Devices on any system are AC
powered and integrated so that if one smoke
detector goes off, all others will follow. Fire
alarm cable comes shielded or unshielded, plenum
or riser rated, and with two to six conductors.
The number of conductors required is determined
by the system being installed. When purchasing
fire alarm cable, its important to make sure you
buy cable tested by a national laboratory and
approved by the National Electric Code. Approved
cabling is appropriately stamped.
