Designed as an OEM-style replacement or new-installation smart card reader for commercial access control systems compatible with the Signo 40K reader family.
Installation should be performed by a qualified low-voltage technician or licensed electrician familiar with access control wiring practices. Disconnect and de-energize the access control panel before terminating any wiring connections. Follow local low-voltage and security system codes when routing and securing the pigtail leads. Consult the system controller documentation to confirm reader configuration and credential profile settings before commissioning.
