  • Doorbell & Telephone Ring Detector

    The ELK-930 performs three functions. It can detect ring activation from one or two doorbell buttons and a single telephone line. It conveniently isolates the voltage and current and produces an open collector (pull to ground) output which can be used to trigger an automation controller, relay, timer, etc. The circuit is pre-scored so that the individual detectors may be snapped off (separated) from each other. The ELK-930 Doorbell Detector monitors the current draw of a doorbell and produces an open collector output when the pushbutton is pressed and the doorbell draws 900mA or more. This open collector output can be used to trigger an automation controller input that utilizes high to low switching (pull to ground) for activation. The ELK-930 Telephone Ring Detector monitors the voltage on the telephone line and produces an open collector output (pull to ground) when the telephone ringing voltage is approximately 50 Volts or greater. The output follows the ringing pattern.

    Compatible With Most Home Automation Systems

    The Doorbell and Phone Ring Detector works with the most common home control systems, including the Stargate, TimeCommander Plus or HomeVision with a Digital BOB. It works with any X10 system when combined with an Powerflash Module. It will also work with any Insteon system when combined with an I/O Linc Low Voltage/ Contact Closure Interface.

    The unit simplifies installation enormously thanks to its pre-scored circuit board, allowing you to snap off the individual detectors. Install the doorbell detectors anywhere in the wiring loop, and the phone detector near easily accessible phone wiring. No need to fish all of your wires to the same location! Both the doorbell detectors and the telephone ring detector get power from the lines, so no external power source is required.

    Works like a charm. Rarely misfires. May require electrician to install, if you don't have basic skills.

    I used the doorbell trigger module to setup my Insteon/Homeseer to detect a doorbell ring which will snap an image from an outside camera. Works exactly as described and was easy to install with directions provided

    This item was worked very well. I like how the circuit board was scored and you could split the board into 3 parts, which was very helpful since I could use it in different areas of the house at the same time. A bit on the pricey side though, so I gave it 4 stars because of that.

    The product was just what I needed for the telephone part, however, I didn't need the doorbell circuits. I should have looked further for just the telephone. Thank You Very Much. Jon

    Still working on setting it up directions were a little confusing and I forgot to order the X10 component for setting it up
