Hate running to your door in rainy weather, only to fumble with your slippery keys before getting inside your warm, dry home? Mount this keypad near your door, and all you have to do is punch in a code (from 1 to 6 digits) and your door will unlock automatically. Prevent your kids from being stuck outside after school, or from trying to break into your home by climbing in dangerous areas! No more re-keying your home every time you or someone in your family loses keys! Requires Doorstrike and 12-24-Volt AC/DC Power Supply (sold separately). What's Included # Keypad and Control Module SC-20-B The keypad can grant access to doorways with either a magnetic lock or an electric strike. The system is designed for up to 20 user codes of 1-6 digits each, allowing you to have a number of authorized entrants, without having to share codes. Also, because each person has their own customized entry code, instead of a single code that everyone has to try to memorize, it makes it easier for your family members and friends to remember their codes. The keypad is completely weatherproof, so you don't have to worry about damage from inclement weather or sprinklers. It also features EEPROM memory, so that the unit will not lose its programming in the event of a power loss and you won't be locked out of your house! Powered by 12-24 VAC/DC.
