The i-Button SALTO Modular wall reader with key pad includes a PIN keypad specially designed for outdoor installation on uneven surfaces. The key pad provides increased security as dual identification is needed to access the door. This wall reader reads data from the carrier and then communicates it to the door controller. It also allows for updating of the carriers via SALTO Virtual Network technology. The reader is IP46 compliant and features a built-in stainless steel external case making it suitable for use indoors and out, including environments exposed to harsh weather conditions.
