This device detects when your physical landline telephone line is cut. When the device detects a phone line cut, (no voltage in the phone line), the device will automatically switch your alarm's landline phone connection to a backup phone source, such as a cellular communicator or dialer.

This device is very simplex and no programming is required. Simply connect your primary phone source (landline telephone line) to LINE 1 on the back of the unit. Connect your secondary phone source (GSM Dialer or Cellular Communicator) to LINE 2. Then connect your alarm system to the TEL-OUT port. The terminal marked "Alarm" is not used in this application and should remain an empty port.

A relay inside the device automatically switches the phone line source from LINE 1 to LINE 2 when a phone line cut (no voltage) is detected on LINE 1. The output to your alarm and/or house phones are always transmitted through the TEL-OUT port.


======= FAQ =======

Q: Will this device work with VOIP phone lines?
A: Yes, but it will only detect if the phone line between your alarm and VOIP box has been cut. It does not detect if an outside cable line feeding the VOIP box has been cut.

Q: When connected to VOIP, if the power goes out will this device switch to LINE 2?
A: Yes, as long as your VOIP box isn't outputting any voltage during the power outage, this device will detect no voltage in LINE 1 and switch to LINE 2. When power resumes, this device will automatically switch back to LINE 1.

Q: Will this device switch to the secondary phone source (LINE 2) if there's no dial tone on primary source (LINE 1)?
A: It depends. As long as LINE 1 has been physically cut, it will switch to LINE 2. However, if LINE 1 simply looses it's dial tone and still has voltage on the line, this device will not switch to LINE 2. LINE 1 must loose it's voltage in order for this device to switch to LINE 2.
