DSC PowerSeries PG9984P Motion Detector

This sensor uses both passive infrared and microwave technology simultaneously. It only triggers an alarm when both sensors detect movement, which helps filter out environmental triggers like sudden temperature changes or air currents that might fool a standard infrared-only sensor.

The PG9984P is designed with pet immunity for animals weighing up to 88 pounds. It is calibrated to distinguish between the heat signature and movement patterns of a human versus a pet, so your larger pets should not trigger false alerts.

The unit features a built-in LED link quality indicator. This allows you to verify the signal strength and optimal placement directly at the sensor location, so you do not need to constantly walk back and forth to check your main alarm keypad.

Anti-disguise mode is a security feature that prevents someone from intentionally trying to bypass the sensor by masking their body heat. It ensures the detector remains effective even if an intruder attempts to use techniques to hide their thermal signature.

The sensor is powered by a 3V CR123A lithium battery, which has an expected lifespan of approximately 60 months under normal operating conditions. You will not need to worry about frequent maintenance.

No, this specific model is designed exclusively for indoor use. It is rated for operating temperatures between -10°C and 55°C, but it is not weather-sealed for outdoor environments.
