Lifesafety Power FPO75-B100C8PE4H/T4-C 75W Power Supply with 8-Channel Relay Lock Control
Overview
The FPO75-B100C8PE4H/T4-C is a 75W managed power supply designed to feed and supervise door locks, magnetic strikers, and access control solenoids across multiple entry points in commercial installations. It delivers 6A at 12VDC or 3A at 24VDC, distributed through eight supervised relay outputs rated at 2.5A each—enough for a typical four-to-eight-door deployment without cascading multiple units. Each output is independently selectable for failsafe (power-loss releases door), failsecure (power-loss locks door), or FAI (Fire Alarm Interface) logic, letting integrators tune response per door without wiring changes.
Compatibility
This supply integrates with standard 12VDC or 24VDC electromagnetic locks and strike mechanisms. It is compatible with access control panels and fire alarm systems that require relay supervision and failsafe/failsecure switching. Verify the control protocol (relay closure vs. voltage signal) with your panel documentation before commissioning.
Key Specifications
Power delivery: 75W total capacity split across 8 relay outputs at 2.5A max per channel—sufficient for medium-duty solenoid loads; undersizing a single output prevents brownout across the board. Output voltage: Field-selectable 12VDC or 24VDC; 24V reduces conductor gauge on long runs and is preferred in noisy RF environments. Supervision: Each relay output includes power-loss and short-circuit detection, critical for fire-code compliance and tamper alerting on door hardware. Operational modes: Per-output selection of failsafe (unlocks on power loss), failsecure (locks on power loss), or FAI mode for fire-alarm-triggered releases.
Installation Considerations
Size and mount location near power entry and distribution panel to minimize voltage drop on 18–22 AWG lock wiring. Coordinate relay output assignment with fire marshal requirements and access control logic before final commissioning. Current backorder status; confirm lead time with your distributor before scheduling install.
