Lifesafety Power FPO250-4D8E8P Supervised Power Supply
Overview
The FPO250-4D8E8P is a 250-watt supervised power supply designed for distributed security and access control deployments where multiple 12VDC loads require monitored delivery and battery backup capability. Supervision features—such as low-voltage detection and output status reporting—help integrators identify power faults before field devices fail, reducing downtime in multi-building or warehouse automation environments where power distribution spans multiple zones.
Compatibility
This supply integrates with supervised power supply systems and security control panels that require 12VDC auxiliary power. The FPO250-4D8E8P outputs four independent channels, each capable of delivering power to multiple devices per channel, making it suitable for hybrid deployments mixing access readers, locks, sensors, and low-draw network equipment. Check your control panel or power distribution diagram for compatible voltage and supervision protocol requirements before installation.
Key Specifications
Output Capacity: Four outputs rated at the 250W aggregate limit—practical maximum of approximately 62.5W per channel if evenly distributed, or allocated based on per-channel load requirements. This topology enables selective load management and individual channel supervision.
Battery Backup Support: The FPO250-4D8E8P accommodates battery integration for emergency power holdover, critical in access control and surveillance scenarios where power loss must not interrupt security functions. Backup duration depends on connected battery capacity and load draw.
Supervision: Real-time monitoring of each output detects faults, shorts, and low-voltage conditions, triggering alerts to the host panel or monitoring system for faster troubleshooting.
Installation Notes
Confirm input voltage compatibility with your facility power (typically 120VAC or 240VAC), verify per-channel load does not exceed supervised limits, and size backup battery separately based on your desired holdover duration. Coordinate supervision signal routing with your control panel documentation.
