Lifesafety Power FPO250/250/250-4C84D8E12S 250W Power Supply with 32-Output Relay Lock Control
Overview
The FPO250/250/250-4C84D8E12S is a 250W power supply designed to distribute power and relay control across networked access control and security systems. It provides 20A at 12VDC or 10A at 24VDC output—sufficient to power multiple IP cameras and auxiliary devices in a single cabinet installation. The 32 relay lock control outputs (each fused at 3A) support per-output selection of fail-any-input (FAI), failsafe, and failsecure modes, enabling flexible configuration for electric strikes, magnetic locks, and door-control equipment without external relay banks. The 32 dedicated DC auxiliary outputs (also 3A fused, selectable to Bus1 or Bus2) isolate power distribution for secondary equipment.
Compatibility
This unit integrates into access control and surveillance infrastructure where centralized power and relay switching consolidate cabinet wiring. It pairs with standard 12VDC and 24VDC security devices, including door locks, readers, and powered endpoints. Consult the manufacturer technical documentation for specific PoE switch integration and UPS battery backup integration options—battery backup capability is not confirmed in available evidence.
Key Specifications
- Output Voltage & Current: 20A @ 12VDC or 10A @ 24VDC—reduces the number of dedicated power rails needed in the electrical closet.
- Relay Outputs: 32 fused at 3A each; each selectable for FAI, failsafe, or failsecure behavior—eliminates the need for external relay modules for standard access control topologies.
- Auxiliary Outputs: 32 DC outputs (3A fused) assignable to Bus1 or Bus2—allows independent circuit management for sensors, readers, or auxiliary loads.
Installation Notes
Each relay and auxiliary output is fused independently at 3A; verify that connected lock and device loads do not exceed this per-output limit. Configure failsafe and failsecure modes per door security policy before commissioning. This unit is currently on backorder; confirm lead time and availability with your supplier before scheduling installation.
