Installation
Mounting repeaters
:
• Unless directed by the system designer, do not mount repeaters on metal sur-
faces or inside metal enclosures, or where sheet metal ductwork, wire mesh
screens, etc., might block transmissions.
• Outdoor installations require a weatherproof enclosure. (Available separately.)
• The FA5570 housing has an inside knockout to permit wires from power sources
to be brought into the housing from behind the unit.
• The FA5570 also has a removable shutter to permit wires to enter the housing
from the side of the unit.
Power Supply
:
• The FA5570 transformer requires an
unswitched
120VA C po w e r o u t l e t .
• The transformer case should be secured to the electrical outlet to prevent acci-
dental unplugging.
• AC power requirement of repeater: 14VAC transformer (included).
• Backup power requirement (optional): 12VDC.
• Recommended wire requirements: 2-conductor 20AWG (or larger) stranded
tinned copper with PVC insulation rated to 300 volts @ 80°. (Belden #8205, for
example.) Maximum recommended wire length between transformer and
repeater: 100 meters (328 feet). Measure voltage at repeater on long wire
runs.(
Source: Tech Note #1053.)
• Wire runs should be hidden, stapled or protected by conduit.
• Recommended power supply is 200mA, or 20VA at 14VAC.
