4.3.2

Indoor SE receiver installation (Summary)

–

Indoor SE receivers must be mounted in a evenly spaced grid no more than 25 m (80 ft)
apart.

–

Indoor SE receivers must be mounted 1.5 m to 1.8 m (5 ft to 6 ft) above the floor. This is
true even if this is a single story building. Do not mount SE receivers above the ceiling or
in roof rafters.

–

In multistory buildings, the SE receivers must be mounted directly above the SE receivers
on the floor below. The same number of SE receivers must be used on each floor level. If
you meet all of the indoor installation guidelines, you can expect the computed location
to indicate the correct floor about 95% of the time.

–

SE receivers must not be mounted within 30 cm (1 ft) of any metal object, including wire
mesh, metal foil, metal pipe and HVAC ducting in walls.

–

Take care that large metal objects do not shield an SE receiver from a protected area. For
example metal staircases, metal food serving lines, metal walls, lead lined walls, metal
roofs, wire mesh in walls, walk-in freezers and refrigerators.

For the best indoor and outdoor location or an indoor only system

–

Mount the indoor SE receivers on the recommended 25 m (80 ft) grid, with the last row
of indoor SE receivers on the outside wall of the building. Do this even if the building is
less than 25 m (80 ft) wide or long.

–

There should be an SE receiver at each outside corner of a building.

Handling two protected buildings sharing a common wall with floor levels that do not match

–

Ask the customer which building has areas of greater concern and favor the
recommended mounting heights in that building.

–

The recommended 25 m (80 ft) maximum indoor spacing grid should be maintained
throughout both buildings as if the wall in question was not there. Mounting heights only
for those SE receivers at or near (within 6 m [20 ft]) the wall in question should be
affected. Mounting heights for all other SE receivers in the buildings must follow the
indoor recommendation. Mark the recommended mounting height for SE receivers on the
higher floor level and also mark the recommended mounting height for SE receivers on
the lower floor level. Mount the SE receiver at its normal grid location midway between
these two heights, but not above the ceiling level of the lower floor.

4.3.3

Outdoor SE receiver installation (Summary)

–

Outdoor SE receivers must be mounted in a evenly spaced grid no more than 90 m (300
ft) apart.

–

Outdoor SE receivers must be mounted 3 m (10 ft) above the ground.

–

SE receivers must not be mounted within 30 cm (1 ft) of any metal object, including
fences, metal walls and walls with wire mesh. If an SE receiver is mounted on a metal
fence, that fence should be grounded (not floating or insulated from ground) and the SE
receiver should be spaced 30 cm (1 ft) from the fence and 3 m (10 ft) above the ground.

–

Take care that large metal objects do not shield an SE receiver from a protected area. For
example; metal fences, metal staircases, metal buildings, power transformers and metal
roofs.

–

SE receiver locations should be below building overhangs and eaves as these can shield
the areas below them.
