【How This PIR (Passive Infrared) Motion Sensor Alarm Works】① TO ARM: Press the remote or the ‘ENTER’ key on the keypad. You will have a 30-second exit delay to leave the monitored area without triggering the alarm. ② TO DISARM: Once triggered, disarm by pressing the remote or entering PIN code within the first 5 seconds (default – adjustable if needed). Otherwise, the alarm will emit a high-pitched, harsh sound for 30 seconds — long enough to deter intruders or burglars and attract nearby attention. ③After the 30-second alarm ends, the alarm returns to the ARMED state and automatically waits for the next trigger.
【An Ideal Additional Indoor Home Security Alarm】Protects your safety & property – ideal for indoors, garages, sheds, gates, porches, and travel, camping, RVs. Note: Not waterproof.
【Motion Detector Siren】Chose Chime Mode – Gentle alert when motion is detected; ideal as a doorbell, child/pool safety alarm, or sleepwalking reminder. Adjustable Volume – Choose from High / Medium / Low (H-M-L).
【No app required – Simple and user-friendly】Easy to Arm or Disarm via Remote (Key Fob) or Keypad, perfect for the elderly or children. The handy key fob lets you arm or disarm the alarm from up to 100 ft / 30 m away (tested in open fields). Tip: Supports multiple remotes for family members if needed.
【Recommended Operating Temperature: 5°F–95°F】Avoid high temperatures – they can reduce sensor sensitivity/range or cause malfunctions. Installation tip: Keep away from direct sunlight, AC vents, or radiators.
【Portable Freestanding or Wall-Mounted】Perfect travel/camping alarm, bear deterrent, or pet/animal repeller – keeps pets off counters/tables and protects furniture while you’re away. Battery-powered (2 × AAA, not included) or USB-powered (adapter not included).
【Multi-Alarm Linkage Support】Place multiple linked alarms around your home (front/back door, garage, shed, basement – within range). If one is triggered, all linked alarms sound together for a louder, more effective deterrent. No app or Wi-Fi needed.
