ACCESSORIES & REPLACEMENT PARTS FOR CE SERIES AND MODEL DP-1A

PT OPTION: PUSH-TO-TALK BUTTON SWITCH

This factory-installed option consists of a standard “500” style handset with the addition of a
pushbutton switch located conveniently on the handset. The switch-contact arrangement is form
“C” (SPDT) and is wired as form“A” (SPST). Configuration is ideal for use in relay-control, push-
to-call, and a variety of other switch, communication, and signaling applications. It is available
on CE-2A and DP-1A by adding a (-PT) suffix.

DY-1 DYNAMIC TRANSMITTER

This accessory is designed for installations in which the telephone handset would be used as a
paging microphone. The dynamic transmitter is the low-impedance type suitable for input to the
Lo-Z microphone input of the amplifier. Assembly replaces the carbon transmitter with a moving
coil (dynamic, 500 ohms @ 1KHz with a response of 250-5000Hz) transmitter that has an
impedance of 500 ohms @ 1 kHz.

TELEPHONE POWER SUPPLY FOR COMMON-TALK SYSTEMS

TPS24-05 The TPS24-05 is a combination 24 VDC / TALK voltage power supply, engineered to
power most common-talk telephone intercom systems. (See SL5-1425 on DC power supplies
and SL8-1433 for common-talk telephone intercom applications.) Black epoxy finish with a 6’
power cord.

600-OHM IMPEDANCE MATCHING TRANSFORMER

LT600-VC Versatile unit matches line level, 600-ohm line circuits with HI-Z circuits. It can also
be used as a 600-ohm to 600-ohm isolation transformer. Recommended for coupling of line
level audio or common-talk phones into amplified sound systems, background music and paging
systems, recording equipment, or studio electronics. Built-in potentiometer provides optional
adjustability for the 25K output level. The 600-ohm input may be matched to 600, 10K, and 25K-
ohm circuits. All components are mounted on a printed circuit board. Steel chassis includes
mounting ears and “insta-mount” tape. Transformer is shielded to minimize induced hum. Unit
includes a phono jack on the output side for convenient connection to amplifier or other equip-
ment circuitry. Jack can be connected to various transformer taps via barrier strip jumper.
(Factory-installed jumper connects jack to potentiometer output.)
