UPAM-K Universal Paging Access Module Kit

The UPAM-K Universal Paging Adaptor Module Kit designed to provide telephone access to most commonly available paging systems. It works with loop- and ground-start trunk ports, station ports or paging ports, and is compatible with the full range of currently available telephone equipment, i.e., PABX, stand-alone 1A2-Key, Electronic Key, Hybrid Electronic Key, or Centrex.

Overview

The Model UPAM-K consists of the access module, 48-volt power supply, interface transformer and miscellaneous connectors (listed below). The functional unit provides telephone and paging system connections, background music input (BGM) and modular page port connector, switches to select operational features, and adjustment controls. The unit is compact, housed in a steel case and is designed to be mounted on a wall.

24V or 48V operation (trunk port operation)

●

Mode switches let you select 24-volt or 48-volt operation. A 48-volt power supply is included to provide 48-volt trunk port operation (a 24-volt power supply is required for 24-volt operation).

●

Preannounce and Confirmation Tones

A preannounce tone (heard at the telephone and the loudspeakers) or confirmation tone (heard only at the telephone) can be selected with mode switches (one of these modes must be selected for the unit to operate properly). A screwdriver-adjustable control (TONE VOL) sets the level of each. (Note: when used with ground-start trunk ports, only the preannounce option can be used.)

●

VOX Delay Timer

Voice controlled disconnect timer, for use in station port operation is enabled with a mode switch. This automatically disconnects the line after a predetermined interval of silence (from 2 to 6 seconds, set with the

Default Timer

●

A default timer sets the maximum time allotment for paging (6 to 35 seconds, set with the PAGING TIME

control). This timer ensures that the unit will always disengage the line by forcing a disconnect,

if the other disconnect functions are disabled or not available with a specific telephone switch.

Note:

The timer may be inhibited; see Default Timer Modifications on page 9 for procedure.

Background music input jack and volume control

●

An RCA-type jack (BGM IN) accepts background music sources from the paging system. The level can be set with the BGM VOL control. An RCA-jack connector cord and RCA jack adaptors are included in the kit to connect with some common background music sources.

●

Contact Closures

Two normally-open contact closures are provided on the UPAM which change state when the unit is activated. One set is located on the punch block (terminals N.O. and COM), and the other one on the bottom side of the unit (terminal strip). One contact closure can be used for ground start operation. The second contact closure is available to provide control of external equipment or functions. When the UPAM is used on a loop start trunk, page port, or station line, both contact closures become available to provide control of external equipment or functions.

●

Direct connection to page ports through a modular jack on the side of the unit

An 8-conductor modular connector cable is included for easy connection to modular page ports.
