How do I adjust the sensitivity of the sensor?
The TW50 features an internal sensitivity potentiometer. Turn it clockwise to increase sensitivity or counterclockwise to decrease. Start with a medium setting and adjust based on false alarm occurrences.
What should I do if the LED keeps flashing?
A flashing LED indicates a warm-up period (approx. 60 seconds after power-up) or a tamper alarm. Ensure the cover is properly closed. If the flash persists, check the tamper switch connection.
Is the TW50 pet immune?

How do I clean the TW50 sensor lens?
Use a soft, dry cloth to gently wipe the lens. Do not use any chemicals or abrasive cleaners, as they may damage the IR detection window.
What is the recommended mounting height for the TW50?
For optimal performance, mount the TW50 at a height of 2.0 to 2.5 meters above the floor. Ensure the detection pattern covers the area of interest.
Can I replace the battery in the TW50?
The TW50 is hardwired and does not use a battery. It requires a constant 12 V DC power supply from your alarm system or a dedicated power adapter.
What does the tamper alarm indicate?
A tamper alarm occurs when the sensor cover is opened or if the sensor is forcibly removed from its mounting. The tamper switch (NC) opens, signaling an alert. Ensure the cover is properly secured.
