Lifesafety Power FPO250/250-3C83D8PE12M/T24-A 250W Access Control Power Supply

Overview

The FPO250/250-3C83D8PE12M/T24-A is a 250W power supply designed for access control and lock management in mid-scale deployments. It supplies either 20A at 12VDC or 10A at 24VDC, supporting eight relay-controlled lock outputs and eight class 2 auxiliary outputs — typical for door controllers, magnetic locks, and request-to-exit devices in office, warehouse, or multi-tenant facilities.

Relay and Auxiliary Output Configuration

The eight relay outputs are individually fused at 3A per channel, with each selectable for failsafe or failsecure operation — critical where power loss must either unlock (failsafe, emergency egress) or lock (failsecure, security hold). This configurability means a single unit can manage mixed door logic across a facility without custom wiring. The eight auxiliary outputs provide class 2 power-limited delivery (2.5A per output) assignable to Bus1 or Bus2, enabling integration with distributed sensor networks or secondary control nodes without requiring separate power infrastructure.

Voltage and Current Flexibility

Dual-voltage output (12V or 24V, not simultaneous) allows this supply to replace older 12V systems or integrate into standardized 24V lock control environments. The 20A/12V rating supports higher-current solenoid loads; the 10A/24V output suits lower-power, longer-run installations with reduced wire gauges. This flexibility reduces the need for separate SKUs across a multi-site rollout.

Typical Applications

Suitable for secured entry points in warehouses, office suites, server rooms, or access-controlled parking. The eight-relay capacity supports small- to mid-sized multi-door deployments without cascading to a separate access control panel. Pair with door strike controllers and request-to-exit sensors to establish a complete lock supervision layer.
