Safety Information and Cautions
Explanation of Graphic Warning Symbols
This symbol is intended to alert the user to the presence of un-insulated
“dangerous voltage” within the product’s enclosure that may be of
suffi cient magnitude to constitute a risk of electric shock.
This symbol is intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in the literature
accompanying the device.
WARNING! To prevent fi re or shock hazard, do not expose this device
to rain, water, or wet locations.
General Wiring Cautions
DO NOT USE EXCESSIVE FORCE ON PUNCH-DOWN TERMINALS! IF
USING AN IMPACT TYPE 110 PUNCH-DOWN TOOL, SET THE FORCE
ADJUSTMENT TO “LOW” BEFORE TERMINATING CAT-5 CABLES.
The 120 VAC line to the structured wiring enclosure’s junction
box must be run by a licensed electrician.
Individual CAT-5 cable runs from the hub to any station or
audio input wall plate should not exceed 500 feet.
Label all cables for identifi cation at the intercom hub.
DO NOT SPLICE CABLES! Splices are unreliable and defeat
the signal isolation properties of the cable.
DO NOT STAPLE CABLES! Staples cause shorts.
DO NOT RUN 120 VAC ELECTRICAL WIRES INSIDE INTERCOM STATION JUNCTION
BOXES. If you encounter 120 VAC wires running through station junction boxes,
you must have a qualifi ed electrician rerun those wires around the junction box.
KEEP CABLES AT LEAST 18 INCHES FROM FLORESCENT LIGHT FIXTURES, DIMMER
CONTROLS, AND ALL OTHER WIRING. This includes AC wiring, security cable, cordless
phone units, and other control wires. These can cause a “hum” or “buzzing” sound.
Keep all cables away from objects such as heating and air conditioning ducts, metal
construction plates, and anything else with sharp edges that can damage cables.
Intercom Room Station Cautions
DO NOT install room stations in saunas. They will not withstand the extreme heat or moisture.
DO NOT install room stations within 10 feet of other room stations, in the same stud
cavity as other room stations, or facing each other. This will cause acoustic feedback.
