Edwards EST CDR-3 PSNI Coder Module

Edwards EST CDR-3 PSNI Coder Module

The CDR-3 Coder is a microprocessor based system option module that provides audio and dry contact coded outputs. The coder activates in response to alarm information received over a supervised RS-232 communications circuit from a fire alarm panel output port.

The CDR-3 provides five LED status indicators. The module is supervised for loss of RS-232 communications from the host panel. Should communications be lost, the module will enter the fail-safe mode and automatically send a temporal signal from the coder outputs. The supervised PSNI and temporal tone outputs also transmit supervisory tones for circuit supervision. Loss of 24 VDC power, and microprocessor failures are also supervised. Module failure indication is provided with a dry relay contact.
