If you have a hardwired security system set up in your home, you can easily allow entry to a door or gate through a digital keypad. The Digital Keypad With 2-Relay Output will connect to most alarm control panels, and it has two built-in heavy-duty relays, which are programmable for normally open or normally closed. Connect a door strike or gate opener for easy remote access. What's Included # Keypad # Back box # Instructions Program Multiple Codes For Different Levels of Security & Different Responses Up to 111 different user codes can be programmed into the Digital Keypad With 2-Relay Output, including a duress code, which will allow the user to activate the keypad while simultaneously sending a panic signal or activating a telephone dialer to call for help. With over 100 million possible codes and multiple levels of codes, you're ensured of a completely secure product that even features protection against unauthorized use: The keypad can lock out or send a duress call after multiple unsuccessful attempts to key in the code. Two Built-In Relays The Digital Keypad With 2-Relay Output features both a 5-amp and 1-amp relay, both of which are programmable to be normally open or normally closed. A normally closed tamper output is also included. Three LEDs indicate status, and built-in buzzer gives audible confirmation of functions and coding. Additional features include a durable stainless steel face for long-lasting looks and protection and EEPROM memory, which prevents data loss during power failure.
