i-PRO MC-B100C8D8PE4M LifeSafety Power Supply (FPO150-B100C8D8)

The MC-B100C8D8PE4M is a LifeSafety Power FPO150-class access-control supply for multi-door access-control deployments. It provides clean, fused, battery-backed power to door strikes, maglocks, readers, and accessory hardware, with the topology and current capability LifeSafety builds specifically for the inrush characteristics of access-control loads.

Key Features

• 150 W class LifeSafety Power access-control supply
• Selectable 12 VDC / 24 VDC output for lock and reader hardware
• Battery-charging circuit for sealed lead-acid backup batteries
• Individually fused output channels for downstream device protection
• Tamper and AC-fail relays for monitoring by the access panel
• Fire-alarm release input for life-safety unlock
• UL listings appropriate for access-control deployment

Access-control power is one area where saving money on the supply costs much more in field service later. Generic switching supplies appear to work on the bench but cannot handle the simultaneous lock-actuation transients of even a modest multi-door system. The LifeSafety FPO line is engineered to absorb the actuation inrush and keep the regulated bus inside spec across the worst-case combinations the deployment can produce.

Size based on simultaneous worst-case lock current plus reader and accessory load, then add 20 percent headroom and a battery sized for the jurisdiction's life-safety policy. Tie AC-fail and tamper into the access panel for monitoring. Configure fire-alarm release per local code. Replace the battery on a 3-5 year schedule and document the install date on a label inside the enclosure so future technicians know when the battery is due.
