1.1 General Information
This manual is intended to describe the features and functionality in addition to
aiding in the planning, configuring, commissioning and maintaining of the
TC8927 Paging System with Dry Contact.
1.2 Product Description
The TC8927 bridges/broadcasts analog audio and dry contact from a central location
to remote sites. An incoming analog/dry contact signal coming into the primary host
port will be broadcast to 6 slave ports. A backup host port is available for
redundancy. The dry contact channel is typically used to actuate the end equipment
to broadcast the audio. When both Primary and Backup host ports receive signal,
Primary will take precedence.
Diagnostic LEDs are available to quickly identify issues with your analog lines.
