Discription

The PK543A Apartment Intercom Amplifier is a selfcontained unit that does not require an external amplifier. The PK543A is designed for use with 3-, 4- or 5-wire apartment remote stations and provides amplification, control and power circuits needed to operate a complete apartment intercom system. Voice volume control and tone volume control are easily adjustable through the screwdriver opening on the front panel. Additional functions include multiple door entrance operation with the PK502B; AC, DC or Maglock configurations with three selectable delayed door timing modes; post office door lock release; steady or warble call tones; power LED; selectable door button hold timeout; and selectable talk before door interlock (available for 4-wire stations only).

Equipment Location

Suite/Apartment Stations Locate suite stations (also known as remote stations) where convenient for use. Install a housing or back box at the desired location. Entrance/Lobby Panel Use an OH190 series housing and OF190 series frame for flush wall mounting. Use an OF190S series frame for surface mounting. Locate the entrance panel where it is sheltered from weather. PK543A Amplifier Install the amplifier inside the entrance panel when using an OH190 series housing. The amplifier must be installed outside the entrance panel when using an OF190S series surface frame. Refer to Connections section, item #3, on page 2 for further details.

Wiring

Suite/Apartment Stations Stations may be connected in risers using the following cable configurations: 3-wire stations: 1 twisted pair #22 AWG, plus 1 conductor #22 AWG per station in riser. 4-wire stations: 1 twisted pair #22 AWG, plus 1 conductor #22AWG, plus 1 conductor #22 AWG per station in riser. 5-wire stations: 1 twisted pair #22 AWG, plus 2 conductor #22 AWG, plus 1 conductor #22 AWG per station in riser. The maximum cable length is 400 feet (120 meters). Additional risers may be added as needed. Station cables must not be run in the same conduit with (or too close to) electrical wiring or background music, and must not be close to fluorescent lighting or other electrical equipment. Failing to observe this requirement can result in noise entering the intercom audio. Ensure that sufficient amounts of cable are left in the back box to make connections to stations.

Transformer 

Cable wiring must be 2 conductor #18 AWG with a maximum cable length of 80 feet (25 meters). If using #14 AWG wire, this distance can be extended to 200 feet (60 meters). Route cable away from suite station wiring and maintain a minimum of 3 feet (1 meter) of clearance between the transformer and the amplifier. 

Door Release Cable wiring must be 2 conductor #18 AWG with a maximum length of 50 feet (15 meters). See Figure 2 on page 5 for specifics of each door control unit configuration. Note: An SS106 transformer must be used for 24 VAC doorstrike and 12 VDC Maglock applications (8 volt tap required)
