General Description

The SP-2B MNS features typical mass notification messages in an exit-sign style enclosure.
The slim 2-1/2 deep box is made of steel, is painted white and is designed for surface
mounting. The messages are printed in clear within a black box on clear film. The red and
green colors are printed on another sheet behind the words. Both sheets slide into the
enclosure and is secured by a removable side-access panel. The messages will remain
hidden (black) until the light source is activated.

The active message is indicated by illuminating the words from behind using LED light bars
of the required color. This low current, long-life light source provides years of dependable
service. The SP-2B MNS typically operates at 24 vdc - 120 ma. - max.

The standard SP-2B MNS model features two messages: “ANNOUNCEMENT” and
“EVACUATE” as shown above. The SP-4B MNS features four messages in any custom con­figuration.

If you need messages on a larger, more-customizable scale, please refer to the LEDArray
and MegaDot MNS products.
