DETECTION
AND
ACTIVATION
When
the
sensor
detects
a

a
slow
flashing
red
light
appears
in
the
sensor
window.
After
1
to
2
seconds
of
detection,
the
light
flashes
rapidly
and
the
sensor
immediately
activates
the
solenoid
valve
to
begin
water
flow.
The
solenoid
valve
remains
open
as
long
as

user
is
detected.
The
solenoid
valve
turns
off
when

user
is
no
longer
detected.
The
sensor
is
set
to
activate
the
solenoid
for
a
maximum
of
30
seconds
before
automatically
shutting
off.
