SDC FB-4 Output Power Distribution Module Board, (1) Power, 12/24V DC Input, (4) Fused Class 2, On/Off, 12/24VDC (Matches input) Outputs

Streamline power distribution for locks, readers and other access devices with the Security Door Controls FB-4 control panel module. Built for access control, security and monitoring systems, the FB-4 converts a single 12/24V DC input into four individually fused Class 2 outputs, giving you per-device protection and simple circuit-level control. Each output features an on/off switch and status LED for fast troubleshooting and reduced downtime — a practical benefit for busy integrators and facilities teams.

The FB-4’s isolated relay design supports long trigger runs using 22 AWG cable up to 1,000 feet, enabling flexible placement of sensors and push-to-exit devices without oversized wiring. Compatible with 600 series power supplies, this compact door control module fits cleanly into existing panels and helps consolidate power for locks, strike devices, and surveillance accessories. Ideal for security, surveillance, and access control projects where reliability and serviceability matter. Add the SDC FB-4 to your next installation to reduce wiring complexity and improve system uptime — order or contact your distributor today.
