Lifesafety Power FPO250-2C8P2D8PE4 250W 16 Lock Access Control Power Supply
Overview
The FPO250-2C8P2D8PE4 is a 250W access control power supply designed to drive 16 electronically controlled locks and 16 auxiliary circuit outputs from a single enclosure. This unit addresses the core scaling problem in multi-door access control: managing power to a growing number of locks and auxiliary devices (strobes, door sensors, gate operators) without multiplying cabinets across a facility. The E4 enclosure form factor houses both the 20A/12V (or 10A/24V selectable) distribution and integrated circuit protection—standard for warehouse, retail, and office access control deployments.
Compatibility
This unit is compatible with standard Class 2 powered access control devices including electronic locks, solenoid-driven magnetic locks, door strike plates, exit device trims, auxiliary sensor circuits, and strobe outputs commonly integrated with standalone or networked access control panels. The 16 lock outputs are typically wired to individual door circuits via Class 2 cabling; the 16 auxiliary outputs handle low-voltage signaling (2.5A per output maximum) for ancillary functions. Verify your access control panel's relay capacity and Class 2 circuit requirements before deployment—this supply integrates with systems requiring Class 2 rated power, not line-voltage AC installations.
Installation Notes
The E4 enclosure is UL-listed for indoor wall mounting in mechanical or electrical closets. Each of the 16 lock and 16 auxiliary outputs is individually circuit-protected and current-limited to 2.5A per channel, preventing single-point cascading failures. Voltage selection (12V or 24V) is typically jumper-configured at installation—do not change it in service without shutting down the system. The 250W budget (20A/12V = 240W usable; 10A/24V = 240W usable) must account for cumulative lock current draw across all 16 channels simultaneously; a single heavy solenoid lock drawing 4A per pulse will consume one-third of your available budget if activated concurrently with others. Plan lock sequencing or staggered access if total simultaneous draw exceeds capacity.
