bAtteRy sAving timeR
the Pir motion sensors have a unique battery saving
feature which greatly extends battery life.
the Battery saving timer conserves the Pir battery
by preventing activation when it detects continuous
motion, such as in a busy room during the day.
the timer 'wakes' the Pir only when there has been no
motion for 5 minutes.
the PiR will ignore any motion if
the timer has not expired. this is normal operation!
to test a Pir, leave the room for at least 5 minutes and
then re-enter. the red light in the Pir will flash to indi-
cate that it has sensed your motion into the room. if you
don't see the red light you may not have waited long
enough - try again.
leave the
room. Wait 5
minutes. red light
indicates motion
sensed.

energy lithium 9V
battery. unclip cover

then test the sensor.
