The wired interconnection alarms will go into interconnection alarm mode: BI - BI - pause 1.2s, with the red LED flashes, this alarm pattern is repeatedLow battery modewhen the battery voltage below threshold, the red LED will flash once every 40 seconds with a sound of "chrip"Fault modeif the alarm detection signal decays below threshold, the alarm chirp occurs without LED flashes every 40 secondsSilence modepress the test button at least 2 seconds, it will go into silence mode for approx 8 minutes. That will desensitize the alarm sensitivity temporarily. At this time, the red LED will flash once every 8 secondsNo disturb modewhen the alarm device is in low battery mode, in order to avoid disturbing you at night, please press the test button for 3 seconds which will mute this warning tone for about 14 hours. After 14 hours, the warning tone will still go off. The red LED will flash once every 40 seconds during No disturb modeTest modetest the unit to ensure proper operation by pressing the test button. At this time, the red LED will flash once per second with pulsating alarm until test button is releasedNOTEWEEKLY TESTINGIS REQUIRED.Wireless Interconnection Set up:>1234
