3.1. A1 Wireless Siren
The main unit of the alarm system. It emits a loud 120 dB alarm sound and features indicator lights for different zones. It also functions as a doorbell chime.
3.2. Wireless Door/Window Sensors
These two-part magnetic sensors detect when a door or window is opened. When separated, they send a signal to the A1 siren.
3.3. Wireless Remote Control
Used to arm, disarm, and switch modes of the A1 siren. It features a sliding cover to prevent accidental button presses.
4. Setup
4.1. Battery Installation
The A1 siren and door/window sensors require AAA batteries. The remote control uses a different type of battery, typically a coin cell, which is usually pre-installed or included.
