Important Guidelines
Coverage Test
-12
glassed doorways and window areas will usually provide sufficient signal
strength to the area.
Here are some important guidelines that you will want to keep in mind when
preparing to install a Telario System.
•
Know the building fire codes.
•
Keep Control Stations separated by more than 1 meter.
•
Operating Control Stations must installed be 20 meters or more from peo-
ple.
•
Be sure mounting components meet building standards.
•
Follow UL regulations.
First, as an installer, you must have knowledge of the local building and fire
codes with regards to permanent installation of electronic equipment in the
work place or public facility, including overhead or ceiling mount require-
ments.
Second, if you are installing more than one Control Station, be sure they are
separated by at least 1 meter to insure correct RF performance.
Third, you will need to conduct RF performance tests to verify that the system
coverage meets your customer's expectations in all areas within the facility
where system access is intended. If special conditions exist, such as metal walls
or the presence of large metallic objects within the building or if irregular cov-
erage patterns are encountered, preliminary installation may be necessary to
verify operational requirements before the final installation is attempted.
Finally, UL1950 requires that any wall or ceiling mount be capable of support-
ing 5 times the weight of the equipment. Our standard mounting components
can support 25 or more pounds. If you substitute any components, they too
must support at least 25 pounds.
UL1950 also focuses on the physical installation and fire safety of the equip-
ment while Article 725 focuses on the power cabling. We fall under Article 725
because we use a Class 2 power supply. A Class 2 power supply must be UL
listed, must be inherently current limited, and is generally under 50 Volts.
Class 2 circuits generally do not require special handling such as conduit. The
major concern is that Class 2 circuits cannot share raceways, cable trays, or
enclosures with high power circuits such as branch circuits. Article 725 also
states that the cabling must be done in a 'neat and workman-like manner'.
They specifically cite ANSI/EIA/TIA "Commercial Building Telecommunica-
tion Wiring Standard" 568-1991, and "Commercial Building Standard For Tele-
communications Pathways and Spaces" 569-1990 as examples of what would
comply.
Once you have selected the Control Station location, a coverage test is neces-
sary. Place a Control Station into the Error Rate diagnostic mode and position
it as close to the preferred installation location as possible. To get the most real-
istic coverage estimate, you may need to use a telescopic tripod. Then, carry a
diagnostic mode enabled handset to all corners of the facility. Control Stations
placed in diagnostic mode will transmit a continuous 1 kHz tone to the hand-
set. The tone should remain solid with no dropout in all locations. If coverage
is deemed unacceptable in certain areas of the site where it is necessary, choose
a new location for the Control Station and repeat.
