Each floor would require 6 receivers, resulting in a total of 24 receivers to protect this
building.
For the best location accuracy, consistent receiver spacing is important. Do not place
receivers significantly closer in one section of a building than another section.
Number of outdoor receivers
To estimate the number of receivers, first read Outdoor receiver installation. Assume a
maximum receiver spacing of 90 m (300 ft) between receivers, in both directions, for receivers
that are not within 30 m (100 ft) of a building with inside coverage. Receivers within 30 m
(100 ft) of a building should be spaced the same as receivers in the building (spacing the
outside receivers at a somewhat larger spacing is acceptable in most cases).
An outside area directly between two buildings with inside protection will need no additional
receivers if the buildings are 90 m (300 ft) or less apart. If the buildings are more than 90 m
(300 ft) apart the outside receivers should be evenly spaced between the buildings. Make sure
the standard 90 m (300 ft) spacing is not exceeded. For spacing outside adjacent to a covered
building, start the 90 m (300 ft) spacing at the building wall.
Allowance for special coverage requirements
For purposes of the bid, the number of receivers estimated above should be raised by 5% to
allow for special coverage considerations and RF problem areas.
Number of transponders
Assume one transponder per building for indoor installations. If wiring can be run from other
buildings or from outdoor receivers, they may be connected to one transponder. Never exceed
the total number of 64 devices (receivers and alert units) per transponder. All outside wiring
must be under ground, or in metal conduit.
Number of receivers and alert units per bus
For transponders, each bus can handle 8 receivers and alert units. However, it is a good idea
to leave some addresses available on each bus to allow for future expansion. For systems with
a high number of supervised transmitters, see Transponder wiring notes.
