This code lock can do more than simply open a door. By individually assigning code combinations, you can target activation of two different output relays, so that this system is also well suited for controlling plant & machinery. An unbelievably wide range of different code & user combinations is available. If a code is entered incorrectly 10 times, the keypad can be locked or a quiet alarm triggered. In addition, an integrated sabotage contact reliably protects against unauthorized opening of the case. The 3 integrated LEDs can be switched as required to indicate the system state.
