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.

LT600-VC

600-OHM IMPEDANCE MATCHING TRANSFORMER

LT600-VCVersatile 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.)
