About – The Proximity readers with Genuine HID Technology™ are for use with the Net2 or 3rd party access control systems. These readers work with standard cards with Genuine HID Technology™, operating at 125 kHz. The Wiegand card data is transmitted untruncated. The reader range includes the Proximity P50M reader with Genuine HID Technology™ and the Proximity metal reader with Genuine HID Technology™.

These readers are pre-activated with 125kHz Genuine HID Technology™ out of the box. There is no need to purchase an activation license to use this technology.

Wiegand output is available with a separate purchase of an activation card.

The P-Series readers are supplied with black fascias (bezels) only. Replacement fascias (bezels) are available in black and white/gray.

Installation – The Proximity readers with Genuine HID 125kHz Technology™ come with 3m of cable and can be wired as shown on the control unit label. Be sure to avoid mounting on metal surfaces or near other proximity readers as this will affect the read range. The cable exits centrally from the back of the reader making drilling and mounting very accurate.

Operation – A token is read by holding it within close proximity of the reader. Once a token has been read the control unit looks up the access permissions of that user. Access is then granted or denied as appropriate. If access is granted the green LED flashes, if access is denied the red LED flashes.
