alpha IA543 Intercom Amplifier
Introduction
The Alpha Communications® IA543 Intercom Amplifier is designed to allow two-
way communications between an open voice lobby panel and multiple apartments.
Additional equipment will allow communications with multiple entrance panels.
Entrance panels will signal up to an apartment by pressing the corresponding
call button, and the resident can answer using TALK and LISTEN buttons. A DOOR
button provided on the apartment station can be configured to operate an
electric door strike or magnetic lock to allow visitor entry.
The IA543 is compatible with additional equipment to provide specialized
applications and features such as hearing impaired strobe lights, multiple
sequenced door operations, integration into access control systems, and Postal
Lock release(s).
INSTALLATION PROCEDURE
Read this manual to insure proper wiring, component placement, and installation methods.
WIRING REQUIREMENTS
Depending on the facility layout and number of apartments, inside stations may be connected by risers comprised of common wires with selective wires from each inside location, or connected in a home run method from each inside location. Apartment stations can be of the 3, 4, or 5 wire varieties and can be used in combination if necessary.

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.
DOOR RELEASE DIAGRAMS
Set jumpers as shown in the chart below. This supplies 16VAC to the door
strike through the K & D terminals when the inside station DOOR Button is
pressed.
The length of activation time is determined by the dipswitch settings (approx.
2, 10, or 25 seconds).
Set jumpers as shown in the chart below. This example shows the wiring for a
Multi-Tap Transformer (8/16/24 VAC) to supply 24VAC to a door strike when the
inside station DOOR Button is pressed, while also supplying 16VAC for system
power. Pay special attention to the transformer wiring and terminal markings.
The length of activation time is determined by the dipswitch settings (approx.
2, 10, or 25 seconds).
Set jumpers as shown in the chart below. This configuration supplies
continuous 24VDC to a magnetic lock through the L+ & L- terminals which is
shut off when the inside station DOOR Button is pressed allowing the door to
be opened. Insure that proper polarity is observed.
Set jumpers as shown in the chart below. This configuration is used when a
magnetic door lock has its own dedicated power supply. The PK407A only
provides a dry contact which in this Normally Closed mode, allows voltage to
flow to a magnetic lock through the B & A terminals. When the inside station
DOOR Button is pressed, the relay opens the circuit, disconnecting the power
and releases the door. Insure that proper polarity between the magnetic lock
and its power supply is observed.
The length of door release time is determined by the dipswitch settings
(approx. 2, 10, or 25 seconds).
To use the PK407A as an isolation relay for a door strike with a separate
power supply, the wiring and jumper settings are the same as above, except the
wire going to the B terminal (Normally Closed) would go to the A terminal
(Normally Open) instead. This way power from the IA543 would close the
connection to apply power to the door strike and release the door.
Dipswitches #1 & #2 set the length of door release time for approx. 2, 10, or
25 seconds (See chart above).
Dipswitch #3 will provide a tone at the entrance panel when the call button is
pressed.
(you must use ZW as your tone wire to the entry panel).
Dipswitches #4 & #5 allow the Postal Lock to release the door for 25 seconds
independent of the #1 & #2 setting.
(works only with 4 wire stations).
Dipswitch #6, when OFF, will only allow the door to release for the time
determined by the position of #1 & #2.
If ON, it will continue to stay on past the normal time delay until the DOOR
Button is released.
Dipswitch #7 when OFF, will require the TALK button to be pressed before the
DOOR Button will release the door.
If ON, the Door release can be activated without talking first.
| J1 | Default is jumping the 2 & 3 pins. Changed for special applications only. |
|---|---|
| J2 | Default is jumping the 1 & 2 pins for Door Strike application (power on |
activation)
Jumps 2 & 3 pins for Mag lock application (power off on activation)
JPS| Default setting is not jumped.
Jump to provide 24VDC at the L+ and L- terminals.
MAIN SYSTEM DIAGRAM
The IA543 amplifier has two serviceable adjustments for Voice Volume and Tone Volume located through two access holes on the front cover. Use a small screwdriver and do not use excessive force. Carefully turn clockwise to increase the volume. High volume setting may result in feedback oscillation.

IMPORTANT NOTES
Terminal Pis 24VDC+ for use with strobes only. Connecting other wires or
components will damage equipment.
Run twisted/shielded wire to front speaker away from other wires to prevent
excessive system noise.
Use 22 gauge twisted pair wire unless otherwise indicated on diagram.
