Standalone chime with 90 dB alert

The Emerson TL-80 is a self-contained PIR motion sensor that sounds a 90 dB alarm and flashes a red light when movement is detected within a 6 m range. It suits shops, offices and homes that need a simple visitor alert or intruder deterrent without a wider security system. Battery or USB power gives placement flexibility where wiring is impractical.

Replaces basic entry bells and unmonitored sensors

The unit upgrades a passive door chime by adding motion detection and a choice of 13 melodies, including four dog-bark tones, with five volume levels. The jump is worthwhile when you want both a welcome sound during business hours and a louder alarm after hours, but it does not suit buyers who need smartphone notifications, camera integration or multi-zone coverage.

Screw or tape mounting with angle adjustment

Installation uses the supplied screws or double-face tape; the sensor must be angled so its 110° horizontal and 45° vertical detection zones face the expected traffic path to avoid false triggers. The device is not waterproof, so outdoor use is not supported, and the package excludes the required USB adapter or three AAA batteries.

Questions about this item

What are the exact dimensions and weight so I can check if it fits my door frame?

The sensor measures 1.58 inches wide by 2.1 inches deep by 3.3 inches high and weighs 0.17 pounds.

How do I mount it and which step do people often miss?

Use the two supplied screws or the double-face tape; the step often missed is angling the unit so the 110° horizontal and 45° vertical detection zones cover the approach path perpendicularly to avoid false triggers.

What power options will I need to maintain or replace over time?

It runs on three AAA alkaline batteries or a USB cable with a separate AC adapter; neither batteries nor adapter are included, so plan to replace the batteries periodically or keep the USB supply connected.
