Practical applications of the Golmar 13.56MHz NFC Standalone Access Control Reader
Example 1. Access control in a residential building with SUPRA entrance panel:
In a community entrance fitted with a Golmar SUPRA panel, the S3501/NFC module allows residents to open the door using NFC cards, key fobs or compatible Android smartphones. Its user capacity makes it especially practical for buildings where access credentials need to be managed easily and securely.
Example 2. Professional access solution with two relay outputs:
In offices, technical rooms or parking areas, the two potential-free relay outputs can be used to control two doors or combine a main access point with an auxiliary function. Its flexible power input allows installation using 12Vac or 18–24Vdc, and the entrance panel power supply may be used when the installation allows it.
