Wireless Door Alarm System
Site Survey
The most accurate way to locate the optimum position for repeaters
is through a site survey. PTI Security Systems has a site survey kit
available for trained installers.
The survey kit allows the installer to read the signal strength of
every door transmitter on the site at the receiver. Repeaters are
then located where the signal strength readings are weak.
NOTE: the installer must be specifically trained in the operation
of the PTI survey kit.
Post Installation Test
Though less accurate than a site survey, this method still provides
good placement locations for repeaters.
Always perform a walk-through test after mounting each repeater,
activating each transmitter near its location and checking for an
appropriate response. After the security system is completely
installed, the installer tests every door transmitter on the site over
a period of one to two days. The installer looks for transmitters that
fail to check in or do not report door activity. This indicates a weak
signal to the receiver.
Repeaters are then installed near the transmitters that exhibit
these symptoms. The repeaters’ increased signal strength creates
overlaps in their transmission range, resulting in stable signal
strength throughout the site.
Repeater Location
Place repeaters as high as practically possible, in a sheltered
location, as far away from metal objects (duct work, mesh screens,
boxes), and not subject to physical damage. Repeaters should be
mounted with as few obsticles as possible between them and their
receiver. Each repeater must be installed near a 120 VAC outlet, or
run wiring from the nearest outlet to the repeater.
