Atlantic UV STERALERT™ Lamp Status Alarm With Internal Sounder, Complete With Mounting Collar(Steralert Lamp Status Alarm 30 0090c)

This product is an Atlantic Ultraviolet 30-0090C STERALERT™ Lamp Status Alarm with Internal Sounder, Complete with Mounting Collar.

STERALERT™ Lamp Status Alarm, Model 30-0090C, is an economical device that produces a high-pitched tone when a water purifier has stopped working due to power failure or lamp failure. The device is battery operated and is positioned on top of the sight port plug of either a SANITRON® or MIGHTY★PURE® ultraviolet water purifier to sense the visible light output of the germicidal ultraviolet lamp (located inside the chamber of the water purifier).

Because it is battery operated, it will also indicate a lamp failure when the AC power to the water purifier is removed. The internal battery is a 9-volt Alkaline, which will last more than a year with normal operation. The audible sound consists of a high frequency tone which is pulsed at two or three cycles per second.
