COMPONENT INFORMATION
APARTMENT STATIONS
Locate stations in a convenient location. Recommended height is 60” A.F.F. for most applications. If inside
stations are flush mount style, install proper back box or housing. Run appropriate wires with sufficient extra
length for ease of service and installation. Avoid mounting near kitchen areas where cooking grime may build
up. Avoid mounting near other electrical equipment that may cause electrical interference and static noise.
AMPLIFIER
Mount amplifier in a clean, dry area away from electrical equipment that could cause noise and interference on
the system. Entry panel back boxes may be used to house the amplifier in some installations providing they
will offer suitable protection from heat, dirt and moisture. Do not mount the power transformer within 3 feet of
the amplifier. Check all wiring for shorts and grounds before applying system power.
TRANSFORMER
The transformer must be mounted in a clean, dry area, and in accordance with all applicable codes, at a
distance of 3 to 80 feet (1 to 25 meters) from the amplifier using #18AWG wire. In cases where this distance
must be exceeded, use a heavier gauge wire to reduce voltage drop.
ENTRY PANEL(S)
Mount all entry panels in a suitable location protected from harsh weather and water. Although many panels
are weather resistant, the more protection you can provide, the longer the life expectancy will be. When
mounting flush style panels, always use protective back boxes or appropriate housings.
In the case of multiple entry systems, additional equipment, such as the IA502 or PK502B multi-entrance
adapter, may be required.
DOOR RELEASE
The IA543 easily allows several door release configurations. Always use a minimum of #18AWG 2 conductor
wire up to a maximum distance of 50 ft. (15 meters). In cases where this distance must be exceeded, use a
heavier gauge wire to reduce voltage drop.
Always run these wires separately from the entry speaker cable to prevent interference and noise.
Special applications may require additional hardware such as the PK407A isolation relay, or RY502A Dual Door
Timed Switcher Relay.
Some applications may require a separate power supply for the door release device. Please refer to the next
page for specific wiring and jumper positions.
When running any audio wiring please make sure not to run too close to any source of electrical interference, such as
fluorescent lights, ballasts, dimmers, other electrical wiring, electromagnetic interference (EMI), etc.
