SYSTEM APPLICATIONS
The Model 640 is suitable for a wide variety of paging applications. The paging terminal is flex-

priority paging, including live breakthrough, for immediate notification of emergency response
teams. Detailed system logs of every page are available to track incident response and manage
risk. In addition, most nurse call systems and other alphanumeric input stations are easily inter-
faced with the paging terminal to send detailed messages to key personnel. The Model 640 also
provides an alarm output for immediate recognition of paging terminal failure.
In-Plant Systems
Many in-plant applications, including industrial, government agencies, and institutions, demand
specific paging operations. The Model 640 trunks can be individually configured to interface
with several telephone line types. This allows possible system access from an internal PABX, a
remote telephone company central office, and a local telephone operator. The paging terminal
also offers talkback paging for two-way communications with mobile or portable radios. In addi-
