This open collector output can be used to trigger an automation controller input that utilizes high to low switching (pull to ground) for activation. There are two basic installation methods: Method 1 requires only 1 of the ELK-930 doorbell detectors and free access to the wires leading from the doorbell transformer. The ELK-930 will activate when the doorbell rings, regardless of a single pushbutton or two (front door, back door) pushbuttons. Mount the ELK-930 at any convenient location along the path of the two wires leading from the transformer to the doorbell. Strip the ends and place one under each of the doorbell detector INPUT terminals. Run a two conductor wire from the doorbell detector output terminals to the automation controller or device to be activated. Connect one wire from the "NEG" terminal to a common NEG terminal of the controller. Connect the other wire from the "OUT" terminal to one of the input zones on the controller.

To filter these pulses into a steady output, an ELK-960 can be connected to the ELK-930(C) to get a timed relay output.
