An Annunciator is a Repeater panel. It is located far from the fire alarm control panel. The remote location is usually where the firefighters will enter the building. A repeater panel could consist of only alarm lights, buttons, or even an LCD display. It has been designed with ease of use in mind, with pre-programmed values for its programming options. The installer only needs to configure the loop and enter text labels using the built-in keypad (optional).
