Mosaic Alarm

Loud 135db Keypad Motion Sensor Alarm Siren for Garage, Shed. Portable Cordless Battery Operated Travel PIR Motion Detector Alert. Freestanding Indoor Infrared Home Security Intruder, Burglar Alarm
Main highlights

【TIPS: High Ambient Temperature Affects the Infrared Sensitivity 】High ambient temperature can cause infrared sensors to low performance(This manifests as decreased detection sensitivity and shortened detection range) or even malfunction. Therefore, during installation, avoid direct sunlight or positioning the sensor towards heat sources like air conditioning vents or radiators.
【Standby Time Up to 2 Years 】Adopts a large battery compartment design, powered by 4 AA batteries for extended runtime. For optimal performance, we recommend using branded alkaline AA batteries with a minimum capacity of 2500mAh per cell (e.g., Panasonic, Duracell, Energizer). Note that many non-brand batteries falsely advertise their capacity. (Batteries NOT included).
【Simple & Reliable Keypad Alert – No App Required】Designed for ease of use, featuring larger and wider keys, especially suitable for the elderly or children.
【Recommended Wall-Mounted Installation Height: 5ft (1.5m)】Installing the alarm too high may reduce sensitivity or hinder motion detection. Detection Range: 20-26ft (6-8 meters) Detection Angle: 120° horizontally, 60° vertically (non-adjustable)
【How This PIR (Passive Infrared) Motion Sensor Alarm Works?】 ①: You must first set up 4 PIN codes each time the battery is replaced. ②: Press the '4' key to arm the system after successfully setting the PIN codes; you will have a 30-second delay to leave the monitoring area without triggering the alarm. ③: Once triggered, disarm the system by entering the PIN code within the first 5 seconds; otherwise, the alarm will sound for 30 seconds.
【Battery Life Notice】If installed in a high-traffic area where the alarm is frequently triggered, the battery will deplete more quickly. In such cases, we recommend using an external USB power supply instead of relying solely on battery power. Includes a 5ft (1.5m) USB power cable. TIPS: USB adapter NOT included.
【An Ideal Additional Indoor Home Security System】for protecting your safety or property. For example, it is suitable for indoor areas, garages, sheds, outbuildings, gates, and front/back porches. It can also be used while traveling for camping, RVs, motorhomes, or touring cars. Please note that IT IS NOT WATERPROOF.
【135dB Extra-Loud Siren (Non-Adjustable Volume)】This alarm emits an extremely high-pitched, harsh sound designed to immediately deter intruders or burglars. While the noise may be uncomfortable for some sensitive individuals, it is highly effective in attracting attention when needed.
