This motion sensor alarm is designed to help protect your property from unwanted intruders. It can be placed to monitor entry points such as front doors, back doors, garages, sheds, and other outbuildings. Equipped with a built-in PIR motion sensor, the alarm activates when movement is detected. Installation is simple and requires no wiring—just insert the recommended batteries and mount it on a suitable surface. When the PIR sensor detects motion, the alarm sounds to alert you of potential unauthorized activity. The device offers reliable motion detection without the need for complex wiring or external power sources. Features: - Ideal for monitoring doors, garages, sheds, and outdoor structures - Built-in PIR motion sensor activates alarm upon detecting movement - Wireless design for easy installation—no wires required - Operates on battery power (batteries not included) - Detection range up to 5 meters with a 105-degree angle Specifications: - Detection range: 3–5 meters, 105-degree angle - Working voltage: DC 4.5V - Alarm sound level: 105 dB - PIR detection range: 5 meters - Power source: 3 x AA battery (not included) - Color: White - Dimensions: 136 x 105 x 27mm (5.3 x 4.1 x 1.1 inches) - Material: Plastic - Package weight: 160g Installation Guidelines: - For optimal detection, position the unit so movement crosses the sensor’s field of view. Mount at the recommended height and angle for best performance. - Avoid placing near heat or cold sources such as air conditioners, heaters, or vents. - Ensure the detection area remains free of obstructions. - Mount the sensor at an angle of 10 to 30 degrees from the wall for maximum detection distance. Instructions: - After powering on, the device enters a 20-second standby period during which detection is inactive. Exit the detection area within this time. - After standby, if motion is detected, there is a 5-second delay before the alarm triggers, allowing time for authorized entry. - If no action is taken within the delay period, the alarm sounds for 30 seconds at 105 dB. - If motion continues to be detected after the alarm stops, the cycle repeats. - The alarm can be deactivated manually using the designated method.
