The Seco-Larm Enforcer Bluetooth Access Controller, Single-Gang Keypad with Proximity Card Reader provides access control via three methods: backlit numeric keypad, a built-in proximity card reader, and over Bluetooth wireless connection. All keypad features and programmed settings are saved directly onto the keypad along with a backup saved onto paired smart devices. Configure your Access Controller via the SL Access App. This app is specifically designed for Seco-Larm Enforcer Bluetooth Access Controllers. The SL Access app provides convenience and security for both user and administrator with streamlined, fully app-based setup and management using integrated Bluetooth wireless technology. There are no codes to remember, and its intuitive, visual app design makes initial setup and on-going management simple and fast. Since all data is secured on the device you also avoid the risks inherent with an internet connection. The keypad supports 12-24V AC/DC universal power, eliminating the need for special programming or jumpers.
