Trouble Condition: "TMPR" (Tamper)
SOLUTION TO SIREN DETECTOR - "TMPR" (TAMPER)
If you see this error message, make sure that the sensor is secured in the bracket and pressed firmly against the ceiling—there should not be any space between the bracket and the ceiling.
TMPR is short for “Tamper” and appears when a sensor is tampered with or not installed correctly. When the Siren Detector is properly installed, the button under the sensor is pressed and the system knows that the sensor is active and ready. But sometimes a Siren Detector bracket is not installed properly and won’t work.
