AMPLIFIER LOCATION
For most applications the amplifier should be located inside the entrance
panel housing. Some entrance panels have provision for mounting the
amplifier on the back of the panel. Keep amplifier away from transformers
and other electrical equipment. Avoid temperature extremes. Normal
operating temperature is 0°C - 30°C. If it is necessary to run additional
wire from the panel to the amplifier, use shielded wire to connect the
microphone.
®
TekTone AM629/649 and AM229/449 Series Apartment Entrance Panels
utilize a speaker, electrostatic microphone, as well as a diode connected
to each push button. If reusing an existing panel manufactured by others,
contact our technical department for installation details.
WIRING
Suite Telephones: Wire suites as shown in the wiring diagram layout Fig.
1. Each cable run requires one cond. #22 common, plus one cond. #22 per
suite. Maximum length is 400 feet (120 meters). Additional cable runs
may be added as needed. Cable should not be run in the same conduit with
(or close to) electrical wiring, background music wiring, or close to
transformers, fluorescent lights, or other electrical equipment. Leave
sufficient cable at each location to make connections. Do not cut cable at
each suite.
Transformer: Wire transformer to amplifier using two cond. #18 wire.
Maximum length is 80 feet (25 meters), or up to 200 feet (60 meters) using
#14 wire. Route cable away from suite phone wiring.
Door Release: Wire door release to amplifier using two cond. #18 wire.
Maximum length is 50 feet (15 meters), or up to 125 feet (40 meters) using
#14 wire. To use a 24 VAC door release, use a TekTone
transformer and connect as shown in Fig. 2. (Route cable away from suite
phone wiring.)
Connections: Make connections as shown in Wiring Diagram, observing
the following notes:
1. Before connecting, make certain wires are free from shorts
or grounds.

screwdriver through the openings marked "VOICE
VOLUME".
2. Buzz volume may be adjusted using a small insulated
screwdriver through the opening marked "TONE VOLUME".
3. Balance adjustment may be accomplished using a small
insulated screwdriver through the opening marked
"BALANCE".
4. Using a small insulated screwdriver, adjust the "VOICE

5. Select a remote handset that is a minimum of 50 feet from the
entrance panel and remove the handset from it's cradle.
