You don't need to change the locks every time an employee leaves your small company. The Anti-Vandal 56-User Keypad installs easily at a locking entry point and releases the door latch whenever a user enters a programmed code of 1 to 8 digits. This keyless entry system includes a 20-amp relay that can operate the door strike or perform any desired switching function. The keypad can function with virtually every security control panel on the market and is suitable for surface mounting or flush mounting in a standard single-gang switchbox. What's Included # Interior keypad # Exterior keypad # 2 cables # Mounting hardware # Screwdriver # Instructions Program the Anti-Vandal 56-User Keypad on site with the included keyboard. Up to 56 different user codes can be programmed and deleted individually, and all codes and other stored data are saved in non-volatile EEPROM memory, which will be unaffected by power failures. Program the duration for the relay contact closure, setting the time the door remains latched or unlatched after the code is entered. You can also set the system to toggle mode if necessary, shifting back and forth between latched and unlatched if required. In addition to controlling the door latch, this keyless entry system can operate an auxiliary output. Set this up to ring a chime, trigger a surveillance camera, or trigger any other notification that an employee has entered. Each user code is programmable to operate the relay, the auxiliary output or both. The Anti-Vandal 56-User Keypad has several security features built in. With more than 100 million code combinations possible, vandals won't be able to access your business by pressing random keys. A penalty timer locks out the keypad for 30 seconds after three consecutive inputs of erroneous codes. Trigger a panic output by programming a specific code, or create an ambush digit, which sends a one-second pulse to the panic output if entered after the last digit of a user code. The Anti-Vandal 56-User Keypad is also available with a 2x6 matrix Mullion-Style layout.
