Using a transponder, receivers, and laptop computer to determine receiver location
Notice!
System software and an area map must be installed on a laptop computer to use this method.
A transponder with long multiplex wires connected to receivers can be used to see actual
alarm location before the receivers are placed. Place the receivers in the proposed locations
wired back to the transponder. Program the receivers with their locations in the
Transponder
Database
. Using the maintenance transmitter and the maintenance alarm database, activate
alarm transmissions within the area surrounded by the temporarily placed receivers. Verify
that the location accuracy is acceptable at all points of concern. If not acceptable move the
receivers, update the receiver location in the
Transponder Database
, and retest. Do not test
outside of the last receiver in any direction, as this gives incorrect locations. Repeat this test
in all areas of different construction and concern at the site.
3.3.2
Indoor receiver installation
–
Indoor receivers must be mounted in a evenly spaced grid no more than 25 m (80 ft)
apart.
–
Indoor receivers must be mounted 1.5 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 receivers above the ceiling or in roof
rafters.
–
In multistory buildings, the receivers must be mounted directly above the receivers on the
floor below. The same number of 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.
–
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.
