Output Drivers for Chimes & Horns

The Output Drivers (Triac Driver, Dry Contact) are an OPTION and are not required for the display to function. The dry contact closure is simply a low voltage, low current relay added to the display. The triac is an active AC switching device. If you have a need for one of these output devices, but do not know which of these devices to order, please call Microframe @ 1-800-635-3811.

If you do not have an existing horn/chime, Microframe does provide the Indoor/Outdoor Horn or Electronic Chime for use with the triac driver.
