DH94 FRM-AI Presence Sensor
The DH94 is a 4-row presence sensor designed to provide safety protection for automatic swinging, sliding, and folding doors.
The DH94 is based on the most reliable active infrared (AI) technology available—Floor Reflection Method (FRM). With FRM-AI up to 32 individual detection zones (floor points) are precisely reflected off of the floor in a rectangular pattern, meeting and exceeding ANSI A156.10 guidelines.
The DH94 is now widely used as an inexpensive method to upgrade existing sliding doors that require safety protection at the threshold of the door opening.
