CriticalLP / Propane SystemVerified against the manufacturer's manual

CO ALARM (65 series CO alarm): the red CO LED flashes and the alarm sounds 4 beeps then is silent for 5 seconds (CO alarm trigger 4-15 minutes at 400 ppm). The cycle continues until TEST/Mute is pressed; the RED light stays on until the CO has cleared, or the alarm reactivates in approximately 6 minutes if CO is still present. The signal table prints the LED as STEADY RED. On -MS interconnected installations every connected unit sounds, but only the alarm that detected CO lights its red LED.
