Wireless motion detector SATEL APD-200 with PIR and microwave sensors, 868 MHz, CR123A battery

The SATEL APD-200 is a wireless motion detector that combines passive infrared (PIR) and microwave sensor technologies to detect intrusions with improved immunity to false alarms. Designed for wall mounting, the compact detector measures 62 × 137 × 42 mm and is suitable for indoor and sheltered outdoor locations. It operates in the 868–868.6 MHz band and is powered by a single CR123A battery, offering up to 2 years of service life under typical conditions. The detector provides a detection coverage of up to 15 m by 24 m with a 90° field of view and is intended for residential, office and small commercial security systems.

Advantages

The dual-technology design merges PIR and microwave sensing to reduce false triggers from pets, drafts or sudden temperature changes while maintaining high sensitivity to human motion. Wireless operation at 868 MHz simplifies installation and integration with compatible alarm panels without the need for wiring. Compact dimensions and wall-mount compatibility allow discreet placement in corridors, rooms and entrances. Long battery life reduces maintenance frequency and supports reliable round-the-clock monitoring.

Suitable for

• Home rooms and corridors where reliable motion detection is required
• Small offices and commercial premises for perimeter and interior monitoring
• Sheltered outdoor areas such as porches or covered entrances

How to use

Mount the detector on a stable wall at the recommended height for optimal coverage and orientation toward the area to be monitored. Install the CR123A battery following polarity markings and perform any required enrollment with the compatible alarm control panel using the detector's wireless pairing procedure. After installation, test the detector by walking through the detection zone to confirm correct alignment and sensitivity. Periodically inspect the housing for obstruction or contamination and replace the battery when the system indicates low power.

Usage recommendations

Place the detector away from direct heat sources, air conditioners and open windows to minimize environmental triggers. For areas with pets, adjust mounting height and angle to reduce detection of small animals and consult the alarm panel settings for pet immunity options. Perform regular system tests and battery checks to ensure continuous protection.
