STS CONCEPT 32 replacement for Protowire 528

The 1306 Series of keyboards and CONCEPT 32 telephone concentrators manufactured by STS Signals Ltd have been developed to provide a modern replacement for the life-expired Protowire 528 concentrator equipment.

CONCEPT 32 systems offer a cost effective, genuine non-blocking concentrator solution that provides high reliability and improved maintainability with full engineering support.

The standard 1306 product range includes 32, 48 or 64 line operator keyboards with speech circuits and signalling data provided by a CONCEPT 32 telephone concentrator available in a wide range of configurations.

Designed for easy installation in desktop or shelf applications, the 1306 Series keyboard provides the Operator with a full range of alarm conditions and offers variable sounder tone and volume control.

The Operator telephone handset is mounted on a matching metal support bracket available in 300 slope or 900 (vertical) arrangement.

Ease of maintenance is fundamental to the design of the 1306 Series keyboards, with all components readily accessible and connectors housed in a recessed rear panel for safety.
