Pleasant Chimes For Your Entry |
| Door Alerts are a great subtle way to monitor people entering or leaving your home or business with a pleasant chime sound. Use a simple magnetic contact chime or an infra-red beam to guard your doorways. We have many different models to choose from to meet needs in homes, libraries, doctor's offices, churches, retail stores, and more! Some entrance alerts can be used as security alarms too. |

| 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.
