The ELT Proximity input unit from ABUS Security-Center stands for efficiency and performance. Despite its compact construction and understated design, this wall reader opens up numerous possibilities when used in conjunction with the SG control units or the AE255F evaluation units. The operation of electrical circuits such as motor locks, elevators or automatic doors can be regulated by inserting an ABUS Seccor chip key, entering a code or verifying with a valid proximity medium. The ELT input unit is also suitable for operating electric door openers.
