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.
