Information About CDR-3
The CDR-3 is an Edwards EST fire alarm signaling accessory designed for integration with compatible EST systems through a supervised RS-232 communications connection. The module decodes alarm codes received from the fire alarm panel and converts them into configured signaling outputs. It provides five LED status indicators and supervises RS-232 communication, 24 VDC power, and microprocessor operation. The module can be mounted in a half-footprint space within a compatible fire alarm enclosure.
Key Features:
- Microprocessor Control: Processes alarm information and generates configured coded outputs.
- RS-232 Interface: Receives alarm code information through a supervised RS-232 communications connection.
- Multiple Code Formats: Supports march-time, temporal, and unique coded signaling configurations.
- Supervised Outputs: Provides isolated supervised tone outputs with a 1.2 kΩ output impedance and 3.5 VRMS output.
- Dry-Contact Outputs: Provides coded relay contacts rated up to 30 VDC at 4 A maximum.
- Fail-Safe Operation: Generates a temporal signal if communication with the host panel is lost.
- LED Status Indication: Includes five LEDs for power, module trouble, and output status monitoring.
- Compact Mounting: Installs in a half-footprint module space within compatible enclosures.
The CDR-3 delivers the reliability and precision required for coded signaling and alarm notification functions in compatible Edwards EST fire alarm systems.
