135dB Remote Motion Sensor Alarm for Garage, Shed, Indoor. Loud Sound Freestanding Home Intruder Burglar Security Siren. Battery Operated Portable Keypad Alert for Travel, Camp. Cordless or USB Power
【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 default 5 seconds (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.
