Wireless security sensor for entry points

The Emerson Zeronedze9onxs4g is a battery powered alarm unit designed for doors, windows, garages or sheds. It combines a passive infrared motion detector with a 105dB siren and an integrated numeric keypad. Home owners or renters wanting a wire free deterrent for a single access point will find it fits the purpose.

Keypad arming and auto reset change daily use

A correct code entered on the keypad disarms the system before entry. The detector allows a 5 second delay after sensing movement so the code can be entered without triggering the siren. After a 30 second alarm cycle the unit resets itself and resumes monitoring. A 20 second warm up period after power on gives time to leave the area before the sensor becomes active.

Covers a 3 to 5 meter range at 105 degrees

The PIR detector senses human movement across a 105 degree angle up to 5 meters away. Mounting at a 10 to 30 degree angle against the wall extends the detection distance. Obstacles, air vents, heaters or coolers in the detection zone will reduce reliable coverage. The unit is not suited for large rooms, multiple entry points or areas requiring zoned monitoring.

Questions about this item

How often will the 3 AA alkaline batteries need replacing with daily use?

Battery life depends on how many times the 105dB siren sounds; each 30-second alarm cycle draws extra power, so expect to swap cells every few months in a busy entryway.

What is the first limit reached during a long intrusion event?

The siren stops after 30 seconds, then the unit enters an auto-reset before monitoring again, so sustained noise duration is the limiting factor.

How much heat or noise does the unit produce while armed all day?

In standby the device is silent and generates no noticeable heat; only the 105dB siren and LED indicators activate during the 30-second alarm cycle.
