Introduction

Window sensors are designed to secure the perimeter of the residential premise, and provide the ability to

Pairing Sensor

Door/Window sensor needs to be paired before installation.

Pull the exposed plastic tab from the sensor. (Figure 1)
The LED indicator will be lit for two seconds to indicate a

Successful booting.

It will blink three times every 5 seconds while scanning the

network.

If network is not found after 100 seconds, the sensor will go

into sleep mode. To wake the sensor again, you need to use

magnet or tamper (Figure 2) to trigger a paring process, and

then sensor will repeat steps from 3 to 4.

Installation

Please make sure that the sensor and magnet is located less than 0.25 inch from each other. For optimal performance, it is

highly recommended to install the Door/Window sensor on the fixed frame and the magnet on the moving part of the
door/window. Place the sensor near the top of the door that close to the opening edge of the door. This is the mounting
location for the sensor.

Use the provided double-sided tape on the sensor. Attach the sensor to the door. Press firmly and hold in place for a few

seconds (Figure 3). Secure it with silicone if needed.

Use provided double-sided tape on the magnet. Make sure the alignment of both sensor and magnet are facing each other

(Figure 4). Press firmly and hold in place for a few seconds. Secure it with silicone if needed.

Spacers are used to raise the level of the magnet to be level/closer to sensor. Install Magnets as shown in Figure 5

Reset to Factory Defaults & Reboot

Operation

The Green Pairing LED will stay off during the normal operation.
The sensor is equipped with a tamper switch. If the cover of sensor is removed, the sensor will send an alarm to the home

controller or security system.

f sensor needs to be factory defaulted (for example, to prepare it for joining with a home controller or security system).

Remove sensor cover.
Remove the battery from sensor.
Depress the tamper switch for three seconds before inserting the battery.
Insert the battery. The sensor should illuminate the LED once when boot-up/initialization tasks are complete.

Release the tamper switch while the LED is illuminated (it will be lit for 4 seconds). The sensor should then
reset to factory default settings and begin searching for any available home controller or security system. If you need to
reboot the device, remove the battery for at least 5 seconds, then re-insert the battery.
Place the cover back on sensor.

Note: Replace Battery with Panasonic CR2450 or Mitsubishi

the performance of the product.

Troubleshooting

with pairing to the home controller or security system:
Separate the sensor and magnet or trigger tamper. The sensor will re-attempt to pair.
If device continues to have trouble pairing, remove the battery for 5 seconds and then re-insert it.
If device continues to have trouble pairing, use “Reset to Factory Defaults” procedure to attempt pairing again.

device was communicating with the home controller or security system but is no longer communicating:

Move the device to a location closer to the controller. Separate and close the magnet or trigger tamper from the sensor. If
the controller successfully shows the sensor's status, then install a repeater so the system's range can reach the desired
location for the sensor.
If the device has been in use for months or years and the failure is sudden, check the controller to see if the

device has a low battery. Follow the instructions provided to replace the battery.
