The Gizmo Engineering alarm annunciator with stack light is a compact alarm box that displays the status of an operation with an LED stack light and produces a buzzer alarm upon an alarm condition. Green indicates a good condition and red indicates and alarm condition. The alarm annunciator consists of a miniature stack light connected to the top of a 5 x 5 enclosure box that’s powered by an AC power cord. It also includes a relay output and a convenient piggyback cord to connect a pump, heater, liquid level probe, or other device. The standard power input is 120VAC and the alarm box can be powered by other voltages such as 12VDC, 24VDC, and 24VAC.
