Lifesafety Power FPO250-B1002C82D8E6M1 250W Power Supply with Relay Lock Control
Overview
The FPO250-B1002C82D8E6M1 is a 250W power supply purpose-built for access control and door lock integration in mid-to-large facilities. It delivers either 20A at 12VDC or 10A at 24VDC primary output, with an adjustable 5–18V secondary output (4A max) that accommodates legacy analog sensors and auxiliary devices. The 16 relay lock control outputs—each selectable for fail-secure, fail-safe, or FAI (fire alarm interface) operation—enable individual software-controlled door strikes, mag locks, and request-to-exit buttons without auxiliary relays. This is the power backbone for multi-door access control installations where you need programmable failover logic at the power supply itself.
Key Specifications and Deployment Benefits
Output Configuration: 20A/12V or 10A/24V primary output supports high-inrush lock solenoids and magnetic door locks simultaneously across multiple doors. The adjustable 5–18V secondary (4A) lets you power 24V sensors and PIR detectors without a separate buck converter, reducing panel clutter and wiring runs.
16 Relay Outputs with Selectable Logic: Each of the 16 relay lock control outputs is fused independently at 3A, isolating a single door strike failure from knocking out the entire system. FAI mode integrates fire alarm dry contact inputs for emergency unlock without controller intervention—critical for life-safety compliance. Failsafe and failsecure modes let you configure each door's unlock behavior on power loss in software.
16 DC Auxiliary Outputs: Additional fused 3A outputs (assignable to Bus1 or Bus2 for redundancy) power request-to-exit buttons, door sensors, and status indicators independently from lock coil draw.
Enclosure and Form Factor: E6 size (30H × 23W × 6.5D) with Mercury back plate and door-mount kit fits standard electrical cabinet rails and surface-mount applications. Compact footprint for distributed access nodes across warehouses or multi-tenant buildings.
Installation Notes
Each relay and DC output carries independent 3A fusing—verify door strike amperage draw does not exceed this limit under cold-start (inrush) conditions. Use supervised wiring best practices for access control installations to detect cable cuts and monitor lock circuit continuity. Battery backup integration (if required) must be sized for sustained unlock hold time on all configured doors during mains loss—do not assume rated amperage reserves for charge time.
