The FSRSI Remote System Indicator is ideal for common system annunciation. It includes four LEDs and a local silence/lamp test switch. The LEDs indicate power status, alarm, supervisory, trouble and ground fault. The silence switch will silence the onboard trouble buzzer if active. The switch can also be used to initiate a lamp test of the LEDs on all connected FSRSIs and FSRZIs. The FSRZI Remote Zone Indicator is used to indicate zone status.
