DynaGen RA400 Remote Generator Annunciator
The DynaGen RA400 remote annunciator lets you monitor a compatible generator from a convenient indoor location. Indicator lamps and an audible alarm notify operators of status changes, warnings and failures without requiring a visit to the generator control panel.
Remote monitoring for your generator
Use the RA400 where maintenance staff or building operators need a dedicated generator alarm panel. It communicates with a compatible DynaGen controller over wired RS485 Modbus RTU. Up to four annunciators can share the communication wiring.
Key features
- 20 status, warning and failure indicators, including two configurable lamps with writable labels.
- Audible alarm for operator notification.
- Two switched inputs for system enable/disable and generator start/stop functions.
- Surface or flush mounting.
- Conformal coating helps protect the circuit board against moisture.
- Optically isolated communications for surge immunity.

Compatibility and selection
Cattron’s current product page and datasheet identify the TG410 and TG600 as compatible controllers. Confirm the exact controller model, firmware and communication configuration before ordering. Compatibility with the TG350 is not established by these documents.
The manufacturer lists NFPA 110, NFPA 99 and CSA 282-00 compliance. Confirm the applicable project requirements and complete system design with your installer; an annunciator alone does not establish compliance for the entire generator installation.
Installation accessories
Cattron lists the ACC0109 8 × 8 × 4 in pull box and ACC0120 AC power adapter as accessories. Confirm package contents and any required controller harness, communication cable, enclosure and power supply with Aurora when ordering. These accessories are not represented as included with this listing.
Follow the manufacturer’s wiring, grounding, termination and configuration instructions. The user manual specifies indoor stationary use; consult Cattron for outdoor or high-vibration applications.
