Lifesafety Power FPO150/250-2C83D8PE4 Dual-Bus Power Supply
Overview
The FPO150/250-2C83D8PE4 is a dual-output power supply rated for 250W (or 150W in single-output mode) that delivers simultaneous 12V or 24V feeds on independent Bus1 and Bus2 circuits. This dual-bus architecture enables you to power security control systems requiring separate low-voltage feeds for field devices and supervision circuits without additional infrastructure. The unit includes 8 Class 2 power-limited DC auxiliary outputs at 2.5A per output and 8 relay-rated lock control outputs fused at 3A per output—each selectable per bus, reducing cabling complexity in access control and entry management installations.
Compatibility
This supply integrates with Lifesafety Power control panels and compatible third-party systems requiring dual-bus 12V/24V architecture. The eight relay outputs support failsafe, failsecure, and FAI (Fire Alarm Interface) modes, making it suitable for hybrid access-control and life-safety applications where door locking and alarm supervision must coexist on the same hardware. Verify your panel's backplane voltage and current requirements against the 20A/12V and 10A/24V rated outputs before purchase.
Installation Notes
Each of the 8 DC auxiliary outputs is Class 2 power-limited to 2.5A—sufficient for magnetic locks, badge readers, and small solenoid gates but insufficient for high-current strike plates. The 8 relay outputs (3A fused per output) handle door controller logic and lock-unlock sequencing. Outputs must be manually configured for Bus1 or Bus2 assignment; no auto-detection. Bus separation prevents fault cascade—a short on one circuit does not disable the other. Refer to installation documentation for jumper configuration (C4/C8 jumper guide and D8 Dual FPO Buss/Flex Cable Kit included) and voltage selection wiring.
