SLIDING DOOR APPROACH
& SAFETY
UP TO 32 INDIVIDUAL
ZONES OF DETECTION
MOUNT UP TO 10'
(3m) HIGH
PATTERN WIDTH
AND DEPTH ADJUSTMENT
The DH94D is a 4-row presence
sensor designed to provide activation
and safety protection for automatic sliding
doors with shallow approaches.
The DH94D 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 DH94D is now widely
used as an inexpensive method to upgrade
existing sliding doors that require safety
protection at the threshold of the door
opening.
