SA-02 Supervised Wireless Magnetic Contact Sensor

SA-02 sensor is a high-quality product that is simple to install and even simpler to use. While developed for Door and Window security, this versatile unit can be used for any application requiring a magnetic sensor solution.

The SA-02’s many features include a local magnetic sensor, a LED indicator, SPS(Smart Power Save) technology to maximize the unit’s battery life, a RF supervisory signal, cover and back tamper detection, and automatic low battery detection.

The SA-02 uses a widely available lithium 1300 mAh high power battery and is compatible with Rosslare Security products from the related Series (H-Series: 868 MHz, G-Series: 433 MHz).
