Lifesafety Power FPO250/250-B1002D8E4M1 250W Dual-Voltage Power Supply
Overview
The FPO250/250-B1002D8E4M1 is a 250W regulated power supply designed for multi-camera and access-control deployments requiring dual-voltage flexibility. It delivers either 20A at 12VDC or 10A at 24VDC, with eight independently fused DC auxiliary outputs—each rated at 3A and selectable for Bus1 or Bus2 switching. This segmentation isolates power branches, reducing nuisance shutdowns across IP cameras and field controllers when a single load spikes. The fixed-output architecture (no battery backup in this model) suits stationary surveillance installations where UPS protection is handled separately or grid power is stable.
Compatibility
This supply integrates into security installations using distributed 12VDC or 24VDC loads—cameras, door controllers, motion sensors, or auxiliary relay circuits. The dual-voltage selector accommodates mixed 12V and 24V ecosystems on the same infrastructure. The fused-output design pairs well with installations where PoE switches handle primary camera power but auxiliary devices (strobes, pan-tilt motors, gate operators) require hardwired 12/24V feeds. Bus1/Bus2 selection enables redundant power distribution or load balancing across multiple field branches without additional isolation relays.
Installation Notes
Verify input voltage matches local mains (assumed 110–240V AC primary, standard for Lifesafety Power units, though confirm on datasheet). Select output voltage (12V or 24V) via front-panel jumper before deployment—this is not hot-switchable. Connect each auxiliary output to its load through appropriate gauge wire; 3A per-output fusing means total draw across all eight branches cannot exceed 24A (assuming all outputs are populated). Inspect terminal blocks for secure contact before live testing. Bus selection (Bus1 or Bus2) is configurable per output; document the assignment in your commissioning log to simplify future troubleshooting.
