| Battery Powered Entrance Alert |
| The SL-40 passive infrared door announcer is a self-contained, battery operated, motion detector. From the detector comes a pleasant sounding chime every time a person enters its detection area. This stand alone unit was designed to detect infrared energy emitted by the human body when in motion, and its performance is unaffected by sunlight, car headlights, reflections, shadows, or colors. It will also operate with a door open or closed. Designed with state of the art electronic components to operate under the most demanding circumstances the SL-40 is ideal for monitoring small office and shop entrances. |
