You don't need to press a button or flip a switch in order to enjoy home automation. By installing the UPB Input-Output Module, you'll be able to control such low-power electrical devices as door strikes, drapery controls, garage door openers, or sprinkler valves when low-voltage events are detected, including at the ringing of a telephone or doorbell or when door or window alarm switches are triggered. The UPB Input-Output Module has three inputs and two outputs, so a single module can control several variations.
