FAQs
Q: How do I reset the system after an alarm?
A: To reset the system after an alarm, locate the control panel and press the reset button. Ensure that the cause of the alarm has been addressed before resetting.
Q: Can I extend the detection range of the refrigerant sensor?
A: No, the detection range of the refrigerant sensor is fixed and cannot be extended beyond its specified radius of 31 feet.
Q: What is the recommended maintenance schedule for the system?
A: It is recommended to perform regular maintenance checks on the system every six months to ensure proper functioning and calibration of the sensors and modules.
