Lifesafety Power FPO75/150-C8D8E4M1 Dual-Output Power Supply Board with Battery Backup

Overview

The FPO75/150-C8D8E4M1 is a configurable power supply board designed to deliver regulated 12VDC or 24VDC to distributed lock control and auxiliary systems in access control and security installations. The board supports two power configurations — 75W (6A @ 12V or 3A @ 24V) and 150W (12A @ 12V or 6A @ 24V) — allowing you to match capacity to your site topology without oversizing. Eight relay lock control outputs and eight auxiliary DC outputs, each fused at 3A, enable direct control of electric strikes, mag locks, and status monitoring devices without requiring separate relay modules. Integrated battery backup (both 12V and 24V) ensures failsafe operation during mains loss, critical for maintaining access during power events. The compact enclosure (20W × 24H × 4.5D inches) mounts directly to existing door frames or control cabinets using the included Mercury/Lenel backplate.

Compatibility

This board integrates with Mercury and Lenel access control systems and matches the electrical interface of legacy power supply architectures in enterprise security deployments. The fused output design is compatible with standard electromagnetic locks, electric strikes, and auxiliary monitoring relays commonly paired with IP-based door controllers. Verify your existing system's voltage requirement (12V or 24V) and total current draw across all outputs before deployment — the per-output 3A fuse limit prevents cascade failures but requires load balancing across the eight relay positions.

Installation Notes

Select either 75W or 150W operation during commissioning; this choice is not field-switchable after installation. Fused outputs protect against short circuits and overload conditions on individual lock circuits — standard practice in access control wiring. The Mercury/Lenel backplate ensures mechanical compatibility with existing door-mounted enclosures. Battery backup activation is automatic upon mains loss, extending security during outages. Allow sufficient ambient ventilation within the enclosure; thermal derating may apply in confined spaces or high ambient temperatures.
