Silent Knight remote annunciators are an indispensable part of any fire system. They can be used to operate and program the FACP from additional locations within the system. In addition to status messages displayed on the LCD, there are LEDs for alarm, supervisory, trouble, silence, and AC power status. On-board piezo sounders audibly indicate alarms, troubles and supervisory conditions.
