Lifesafety Power FPO75/150-C4D8E1 Four Door Access Control Power Supply
Overview
The Lifesafety Power FPO75/150-C4D8E1 is a 75W industrial power supply designed for multi-door access control systems requiring simultaneous 12V and 24V outputs. This is the right choice when you're wiring four or more electronically controlled door strikes, mag locks, or card readers from a single chassis — it consolidates power distribution and eliminates the need for multiple wall adapters in a cabinet or wall enclosure.
Compatibility
The FPO75/150-C4D8E1 supports standard access control equipment: electric strike locks, electromagnetic door locks (mag locks), card readers, keypads, and request-to-exit sensors that operate on either 12V or 24V DC. It is compatible with most commercial access control panels and lock hardware commonly used in office buildings, warehouses, and retail environments. Verify your specific lock and reader voltage ratings (usually marked on the device or in the installation manual) before mounting to ensure the 75W budget is sufficient for your configuration.
Installation Notes
Mount the FPO75/150-C4D8E1 in a DIN-rail or wall-mountable cabinet near your access control panel. The dual 12V/24V output design allows you to mix voltage requirements on the same supply — useful when some readers run 24V and some door strikes run 12V. Calculate total wattage: sum the rated draw of all four doors' locks and readers. If the combined load exceeds 75W, upgrade to the 150W variant or deploy a second supply. Ensure adequate ventilation around the power supply to dissipate heat during continuous operation, especially in summer or enclosed cabinets. Standard 24/12V DC wiring practices apply — use appropriate gauge cabling (typically 18–12 AWG depending on run length and current) and secure terminal connections to prevent intermittent contact failures.
