MicroStat Status Indicators 

The Federal Signal MicroStat is a compact, Type 4X status indicator, Type 1 with optional sounder. Ideal for OEM applications, the MicroStat comes pre-assembled as 1-,2-,3-,4- or 5-high light units. The user selects combinations from 5 colors; Amber, Blue, Clear, Green, and Red. O-Rings between each segment provide a water-tight and dust-tight seal. The MSL1, MSL2, MSL3 are available in 24VAC/DC and 120VAC. The base of each light can be surface or pipe mounted (3/4 inch NPT).

The lenses lock together and snap apart with a simple twisting motion, allowing for easy lamp changes and quick lens resequencing. A rugged vibration-resistant, thick-filament wedge lamp fills each lens with light, providing excellent optical performance.

Wire connections are made through a 2-piece terminal block. The MicroStat is designed to work with PLC outputs including "Triacs".

An optional 100,000-hour LED light source is available in the five colors. This lamp, made of surface mounted LEDs, plugs directly into the same socket as the standard lamp.

An optional sound module can be installed in the top position of any MicroStat. The Sound Module Kit (MSS) consists of a slotted girlle and board-mounted piezoelectric horn. The sounder plugs directly into the wedge socket. Sounder is optional as one of the 5-units.

A pipe mount base, pipes and flashers are also available.
