When you don’t have access
above or below the wall, try
to estimate the existing cable
and pipe locations from the
positions of electrical outlets
and plumbing fixtures on
both sides of the wall. Also,
take a look at the outside of
your house, sometimes a
conduit, vent or drain pipe
will be visible and will offer
useful information. Choose
the route with the fewest
potential obstacles. If your
house is built on a slab or
you are wiring between two finished floors, look for base-
boards which could be removed and replaced with the cable
behind them. Doorjambs can be removed and often have
enough space for sensor cable all the way around the door
(
Figure 14
).
Sometimes, an under-the-carpet run is possible. As a last
resort, heating and air conditioning vents can be used as cable
raceways for plenum rated cable (check your local building
codes, some municipalities require a conduit).
