If the FLOW HI or FLOW LO light is illuminated on your Xtralis Smoke Alarm, take the following steps: * Make sure the sampling pipes are correctly installed, the lid is fitted, and the box is fully sealed. * Confirm that the flow calibration procedure has been carried out. * Check and clean the filters. * Verify that the fan is operating normally. * If using flexible tubing, check for pinches or kinks. * For duct applications, ensure the inlet and exhaust tube holes are free from obstructions.
