About – K series keypads are for use with Switch2 and Net2 systems. The K series keypads are supplied with black bezels only, that can be fitted in the final stages of installation. Replacement bezels are available in black and white/grey, and are free of charge to Paxton registered installers from the Extranet. Installation – The keypad is wired as shown on the control unit label. The cable exits centrally from the back of the keypad making drilling and mounting very accurate. Operation – A code is entered using the keypad. The control unit checks the validity of the code and grants or denies access as appropriate.
