– Take care that large metal objects do not shield a 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 receivers on the recommended 25 m (80 ft) grid, with the last row of
indoor 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 a 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 receivers at or near (within 6 m [20 ft]) the wall in question should be affected.
Mounting heights for all other receivers in the buildings must follow the indoor
recommendation. Mark the recommended mounting height for receivers on the higher
floor level and also mark the recommended mounting height for receivers on the lower
floor level. Mount the receiver at its normal grid location midway between these two
heights, but not above the ceiling level of the lower floor.
3.3.3 Outdoor receiver installation
– Outdoor receivers must be mounted in a evenly spaced grid no more than 90 m (300 ft)
apart.
– Outdoor receivers must be mounted 3 m (10 ft) above the ground.
– Receivers must not be mounted within 30 cm (1 ft) of any metal object, including fences,
metal walls and walls with wire mesh. If a receiver is mounted on a metal fence, that
fence should be grounded (not floating or insulated from ground) and the 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 a receiver from a protected area. For
example; metal fences, metal staircases, metal buildings, power transformers and metal
roofs.
– Receiver locations should be below building overhangs and eaves as these can shield the
areas below them.
– Receivers should have a clear line of sight of the protected area. Therefore, take care
where the ground is hilly or uneven, that there are no areas and low spots where several
receivers can’t hear the signal.
Transition areas between indoor and outdoor areas
– An outside area directly between two buildings with complete indoor protection will need
no additional receivers between the buildings, if they are 90 m (300 ft) or less apart.
– When protecting an outside area directly between two buildings with complete indoor
protection, and they are more than 90 m (300 ft) apart, place a row of outside receivers
evenly spaced between the buildings. Make sure the receiver row does not exceed the
standard 90 m (300 ft) spacing from the buildings. The spacing between receivers in that
row should be about the same as the spacing for the receivers in the buildings.
