1. Door Sensor Installation
Fig. 3
Before final installation, please test the alignment on the door (or cabinet) you identified to monitor. Please follow the
simple steps below for headache-free installation.
Note : Sometimes door frames are not flat, as shown in Fig. 6 below. The solution is often to install the smaller
magnet on the door frame, instead of the larger sensor part.
(1) Remove the battery tab from the sensor. (2) Peal off the oval shaped double sided-tape (pre-installed on back of
magnet and sensor) (3) Lightly press the sensor on the door frame and the magnet on the door, so they are aligned less
than 3/4 inch apart when the door is closed, as high as you can comfortable reach (at least 3.5 ft. (100 cm) from the floor).
There is no ‘right-side-up for the door magnet or sensor. See Fig.’s 4 and 5 below. If the door or the frame is not a flat
surface see Note 1 below. (4) If you see a blue light flash on the sensor when the door or cabinet is opened (or separated
by more than ¾ inch), you’re ready for final installation, by firmly pressing both the magnet and the sensor for 10
seconds in place. If you do not see the blue light indicator, please see the Troubleshooting section at end of this guide.
