Traditionally, all security systems used low voltage wiring which was strung through
wall and flooring space. This kept the wires out of site and out of harms way.
It's only recently that the security industry has gravitated to wireless security
systems which are now accounting for more than 50% of new security system
installations.
Hardwired security systems consist of a main panel
that contains all of the basic electronic processes, transmission and signalling
instruments. This electronic console is directly wired to the sensors, sirens
and remote keypads located throughout the house. The best time to have hardwired
security systems installed is when the house is being built. After floors, ceilings
and walls have been built, the wires must be strung through the spaces
using special installation tools. Sometimes holes have to be cut and trimming must
be removed to put wires in place.
A post-construction installation
then is expensive because of the labor involved. Installing a wired system before
the drywall has been put up, may actually be less expensive than a wireless
security system. |
