PK-543 3-4-5 Wire Intercom Amplifier Wiring …

1 WIRINGS uite Stations - may be wired in risers as shown in the wiringlayout diagram, Fig. 1. Each riser requires one twisted pair,#22 (or as required for type of station) plus one conductor,#22 for each suite served by the riser. Maximum length is400 ft. (120 meters). Additional risers may be added asneeded. Cable should not be run in the same conduit with(or too close to) electrical Wiring , background music wiringor very close to fluorescent lights, dimmers or other electri-cal equipment. Leave sufficient cable in each box to makeconnections. Do not cut cable at each - Wiring should be 2 conductor, #18. Maximumcable length is 80 feet (24 meters), or up to 200 feet (60 meters)using #14 wire .

2 Route cable away from suite station Release - Wiring should be 2 conductor, #18 cable. Maxi-mum length is 50 feet (15 mtr). To use 24 volt door release, usea LEE DAN PS-30A transformer and connect as in Fig. - Before connecting, make certain wires are freefrom shorts or grounds. Make connections as shown inFig. 4, observing the following not apply power to transformer primary until entiresystem has been installed and all Wiring checked forshorts or grounds. The common wires connecting toterminals 1,2,3,E and 5 should show open circuit whentested with an twisted pair Wiring as shown. Do not interchangewires or reverse wire APARTMENT Intercom AMPWIRING INSTRUCTIONSFig.

If necessary to install theamplifier elsewhere due to temperature extremes, etc., orbecause a small panel is being used, 2 conductor, shieldedcable must be used for the entrance panel speaker wiringand a 1 conductor shielded wire must be used for the Buzz wire (connect shield drain wire to Amplifier terminal G).

4 NOTE: PK-543 should be located at least three feet (1 meter)away from transformers or other electrical equipment andmust be kept away from direct heat or extreme Temp. 0-30 the PK-543 must be located away from the entrypanel, shielded cable must be used for terminals A, G,and Z (or ZW). Connect shield drain wire to amplifierterminal G. In addition, one of the following steps mustbe taken to prevent the possibility of Oscillation occur-ring at the Suite Stations and the Entry Panel Speakerwhen switching from Talk to ENTRANCE TONE switch must be set to the OFF 1N4003 diode must be placed in series with theZW terminal. The anode of the diode must beconnected to the ZW terminal.

With the second dipswitch to the left, the door delay will be approx. 16seconds. To the right, the delay is 8 seconds. #3 ENTRANCE TONE: call tone at entry panel is enabled withthe 3rd dip switch to the right, and disabled to the left. #4 Not Entire System Dead - Check 117 VAC at transformer primary, 16 VAC at transformer secondary,and Wiring to No Talk - Check Wiring to terminals1 and 2 shorted or open, and wiringto entrance panel speaker open orshorted.
