The LiftMaster CPICARD Conversion Interface Card is a factory accessory designed to retrofit select LiftMaster commercial door operators so they can properly monitor approved entrapment protection devices. In upgrade and replacement scenarios, CPICARD enables compatibility with LiftMaster monitored safety sensors—such as monitored photo eyes (e.g., CPS-UN4 or monitored retro-reflective models like CPS-RPEN4)—to help meet current UL 325 requirements for commercial and industrial overhead door applications. By converting legacy/non-monitored safety inputs to a monitored format, the card supports reliable supervision of safety devices, fault detection, and compliant operation when modernizing older operators or replacing non-monitored photo eyes.
This low-voltage interface card installs inside the operator and connects to the operator’s safety input terminals per the model’s installation manual; no external enclosure is required. Once installed and configured, the operator can recognize compatible monitored sensors and alert to wiring faults or misalignment conditions, improving safety and uptime in warehouses, loading docks, and other commercial facilities. Compatibility varies by operator model; always consult the specific LiftMaster operator manual or parts list to confirm CPICARD is supported and whether a monitored CPS input is already built in. For safety-critical systems, professional installation and commissioning are recommended, and entrapment protection must be tested regularly according to UL 325 and the operator’s instructions. Not intended for residential openers or non-compatible brands.
