TFT MODEL EAS 911R4 ENCODER / DECODER

MODEL EAS 911R4 ENCODER / DECODER
The EAS 911R4 is an FCC Type-Certified EAS Encoder/Decoder with four balanced audio inputs, one RS-232C input, a balanced audio output, an RS-232C output, impact printer, and digital voice recorder.

Interfacing an EAS 911 Encoder/Decoder to a station’s automation system can be accomplished easily by using an EAS 941 or EAS 941A Remote Control/Status Module. The EAS 941 provides logic level status information to the automation system; the automation system provides contact closures to the EAS 941 to activate the forwarding functions in the EAS 911. The automation system can be connected in parallel with a user’s control panel switches to permit both manual and automated control of the EAS 911.

System connections include the EAS 941’s ON-AIR and MESSAGE WAITING outputs and its MESSAGE WAITING, SEND HEADER and SEND EOM inputs. A typical system interface is shown in the Schematic; the Sequence of Operations is described below and is illustrated in the Timing Diagram.
