CR2032
This smart door/window contact sensor
is equipped with high-sensitivity Hall
switch and reliable 433.92 MHz wireless
RF communication technology. It is
designed to monitor the open and closed
status of doors and windows, and is an
essential part of smart home security,
property monitoring and automatic
control systems. When the status of a
monitored door or window changes, the
sensor will instantly transmit signals to
the receiving host wirelessly for
immediate alarm and intelligent linkage.

(2) Press the test button. A single flash
of the indicator means the sensor
functions normally. If the indicator does
not light up, open the rear cover and
replace the battery.
(3) Separate the magnetic strip from the
sensor to simulate opening the door or
window. One flash of the indicator
indicates the open signal is triggered.
(4) Reunite the magnetic strip with the
sensor. One flash of the indicator
confirms the door or window is closed.

①Follow the alarm host manual to
activate the sensor learning mode on the
host.
②Place the sensor near the host and
press the test button to send a pairing
signal.
③Pairing is completed successfully.
Press the test button. The
indicator flashes once when
sending the pairing signal
Notes:
· The host will exit pairing mode
automatically if pairing fails within 20
seconds.
· Repeat the above steps if pairing is
unsuccessful.
(1) Position Selection: Install
the main sensor on the fixed
frame of doors or windows,
and the magnetic strip on
the movable edge. Keep the
two parts aligned with a gap
within 20 mm. Do not install
on metal surfaces or near
strong magnetic fields to
prevent signal interference.
①Remove the rear cover to open the
battery compartment.
②Take out the old battery.
③Install a new CR2032 battery of the
same specification.
④Secure the rear cover back in place.
⑤Test the sensor to verify normal
operation.
(2) Installation Steps:
① Peel off one side of the release liner
from the two 3M adhesive tapes, and
attach the tapes to the sensor and
magnetic strip respectively.
② Remove the other side of the release
liner, then attach the sensor and
magnetic strip to the preset positions.

contacts every six months.
· Remove the battery if the device will
not be used for a long time.
alignment of the magnetic strip; replace
the battery; re-pair the device.
(2) Frequent false alarms: Adjust the
installation position; check for loose
magnetic strip.
(3) Signal delay: Reduce the transmission
distance; replace the battery.
