Simplex (562-974) MapNet Power Supply Assembly Board

Simplex (562-974) MAPNET Power Supply Assembly Board

The Simplex (562-974) is a MAPNET power supply assembly board for legacy Simplex fire alarm panels. First, it provides regulated DC power to the MAPNET addressable loop. As a result, addressable devices on the loop receive stable voltage for reliable communication.

Specifically, this is a board-level OEM replacement part. Therefore, it is intended for technicians servicing existing MAPNET-based Simplex systems. The 562-974 keeps your legacy panel running rather than forcing a full panel replacement.

Key Features

• MAPNET addressable loop power supply assembly
• Genuine Simplex OEM replacement board
• Direct board-level swap for compatible Simplex panels
• Maintains original MAPNET loop operation without reprogramming

Compatible Panels

The 562-974 belongs to Simplex’s MAPNET-era control panel family. However, MAPNET hardware spans several generations and revisions. Therefore, we recommend confirming the exact panel model and revision before ordering. Our team can help you cross-reference your existing board against the 562-974.
