CLM-200 Code Lock Module EB Matte Stainless Steel MODESTA. The code lock module serves as an access control system with a code lock unit that can be installed in stand-alone columns or in suitable surface-mounted or flush-mounted frames for outdoor door stations. It is a complete device consisting of a flush-mounted housing and a 2 mm thick front panel made of matte brushed stainless steel with a numeric keypad (12 keys), two potential-free switching contacts, and a connection for power supply. All settings are made using a master code via the keypad (without a control unit): controllable by two independent codes (1-8 digits), contact duration adjustable from 1-99 seconds or switch operation. After five incorrect entries, the code security lock locks for 60 seconds and signals this with an alarm sound. Note: Power transformer is not included.
