Lifesafety Power FPO75-B100C8D8E2-3SL1 Dual-Output Power Supply with Lock Control
Overview
The FPO75-B100C8D8E2-3SL1 is a 75W regulated power supply designed to drive access control systems with integrated electronic lock supervision. It delivers simultaneous 12VDC and 24VDC outputs — critical when deploying mixed-voltage readers, strikes, and maglock hardware on the same circuit. The dual outputs let you avoid the cost and complexity of stacked supplies or custom power distribution boards, reducing cabinet footprint and simplifying field wiring for integrators working with modular security architectures.
Outputs and Lock Management
The unit provides 2A at 12VDC and 2A at 24VDC, plus 8 dedicated lock supervision channels and 8 auxiliary outputs. The lock supervision outputs enable real-time monitoring of electromagnetic lock status — essential for verifying strike integrity and detecting forced-entry attempts without requiring separate supervision modules. The 3 Salto mounting plates included allow quick integration into Salto-based door control ecosystems, reducing commissioning time on multi-door deployments.
Form Factor and Installation
Compact form factor (20 x 16 x 4.5 inches) fits standard 19-inch security racks and wall-mounted cabinets. The 75W capacity handles multiple readers and smaller maglock arrays; sizing decisions should account for peak inrush current during simultaneous lock energization. Pre-wired distribution harnesses and field-terminal layouts vary by integrator preference — consult your cabinet layout before final procurement to confirm adequate thermal clearance around the unit.
Integration Context
This supply pairs with access control systems using distributed 12V/24V reader and strike architectures. It works alongside commercial power supplies and chargers in redundant or multi-zone configurations where backup power is not required. For sites needing battery backup, consider pairing this supply with a separate UPS or standby battery module rated for your lock current draw.
