Description
The RFID Proximity Access System provides controlled access to premises by means of high-security
transponder card technology. These are similar to credit cards in size and appearance, but no physical contact
is required with the reader for the card to be scanned.
When an authorised card is placed within 4 inches of the sensor, the relay output will operate for a preset time.
The system consists of a control unit and a remote sensor unit that can be fitted to the outside of a building.
The control unit simply requires power and relay connections to operate. The sensor unit connects to the
control unit with the cable provided.
The system has the capacity to learn up to 50 transponder cards. Programming is achieved using either a
pushbutton inside the control unit, or from PC connected to the Control Unit RS232 serial port (only two
connections required).
Connection to a PC enables many other functions including; control of the relay output from the PC, data
logging information of which transponder card has operated the system.
The system is supplied in an ABS plastic enclosures and are IP65 rated.
