a tune or a prerecorded programmable voice message. Offers ten tones/tunes or 53 selectable words (English or Spanish) to create a custom message up to four words. The 8-Channel Receiver offers a mirror function that can work with up to four additional 8-Channel Receivers. Devices can be latching or momentary by zone. GSI offers multiple wireless products designed to alert you of several different conditions (such as: an open garage door, mail delivered, a car in the driveway, open exit door, etc.).
