The SafePath™ D38
with patented Human Presence Radar™
(HPR™) is the latest advancement
in microwave motion detection for automatic
doors. It is the only microwave sensor
that provides protection for a person
who enters the door activation zone and
then slows to an extremely slow pace or
stops. The D38 can provide this extra
level of protection because HPR allows
it to actually detect two separate rates
of motion simultaneously.
Like other conventional
microwave sensors, for the D38 to activate
an automatic door it utilizes Doppler
shift radar to detect movements of at
least 2" per second. However, once the
door has been activated the D38's second
level of detection — Human Presence
Radar™ — is enabled. Now motion
down to 1/4" per second can be detected.
This means with HPR™ enabled, persons
virtually standing still will continue
to be detected anywhere in the detection
zone.
Since conventional Doppler
shift radar must initially activate the
door before enabling Human Presence Radar™
there is no additional chance for false
activation of the door because HPR™
alone cannot activate the door.
Human Presence Radar™
gives slow moving, elderly or disabled
persons the confidence that once they
have been initially detected, they can
safely approach an automatic door at any
speed without the door closing prematurely.
