Zetron Model 640 Paging Terminal
MODEL 640 OVERVIEW
The Model 640 is a low cost, fully automatic dial-access paging terminal. The Model 640 is
specifically designed to provide flexible paging for industrial plants, hospitals, and low RCC
applications. The Model 640 supplies the interface between the telephone and radio systems for
paging applications. It performs selective signaling activation and message transmission.
Through comprehensive advanced software, the Model 640 provides features found on terminals
costing significantly more. State-of-the-art microprocessor circuitry combined with meticulous
engineering provides paging capabilities which rival much larger paging terminals. Even the
newest alphanumeric digital display paging formats can be encoded by the Model 640. In addi-
tion, the Model 640 provides a variety of interface capabilities required for connection to the
telco network, analog and digital radio systems, health care nurse call systems, and telephone
answering service consoles.
FEATURES
Every feature available in the Model 640 is designed to create a small, but versatile and easily
managed paging system.
Messaging Formats
The Model 640 supports six types of pages - tone-only (alert), standard voice, live voice (break-
through), numeric-only display, alphanumeric display, and talkback. A tone-only page alerts the
customer that someone has called them, but cannot indicate who or include any other informa-
tion. Standard voice pages play a caller-recorded voice message over a built-in speaker on the
pager. Live voice paging immediately cuts audio through from the calling party out over the air
