The Simplex 562-688 is the factory replacement CDT (Communicating Device Transponder) board designed for use in Simplex 2120 MAPNET II transponder-based fire alarm panels. When the communications loop circuitry on a 2120 panel fails, the 562-688 provides a direct board-level replacement that restores full MAPNET II loop functionality without requiring a complete panel swap.
Key features of the Simplex 562-688 CDT board include:
- MAPNET II Compatibility: Engineered specifically for the Simplex 2120 MAPNET II transponder platform
- Board-Level Replacement: Targets the CDT communications hardware directly, preserving existing panel infrastructure
- OEM Component: Genuine Simplex replacement part ensuring proper fit and function
- Legacy System Support: Extends the service life of installed 2120-series fire alarm systems
- Loop Communications Restoration: Directly addresses failed MAPNET II loop communications circuitry
The 562-688 is the preferred repair solution for facilities maintaining Simplex 2120-based fire alarm systems, reducing downtime and deferring costly full-panel replacement.
