Safety & Maintenance ≤20mm 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. 1. Indicator Light 2. Test Button 3. Sensor 4. Battery Compartment 5. Screw Hole 6. Mounting Bracket 7. Magnetic Strip Power Supply: DC 3V (CR2032 Lithium Battery) Detection Distance: ≤ 50 mm (gap between sensor and magnetic strip) Wireless Frequency: 433.92 MHz Transmission Range: ≥ 100m (in open areas) Operating Temperature: -10°C ~ 55°C Operating Humidity: Less than 95% (non-condensing) (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. ① ② ③④ 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. (1) Failed to trigger alarm: Check (1) Safety Warnings Do not immerse the device in water or expose it to corrosive environments. Do not use the device in flammable and explosive areas. (2) Maintenance · Check magnetic attraction and battery 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. 3 (1) Test the sensor as follows before initial use:Pull out the insulating tab vertically. § 15.19 Labelling requirements. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:(1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. § 15.21 Information to user. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. § 15.105 Information to the user. Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
