My Firex 120-1056C went off in one bedroom last night beeping three times, causing the interconnected system to go off, however the red light on the initiating alarm stayed on constantly afterwards, even after replacing the battery, the alarm then continued to beep once at regualr intervals. I finally had to unplug it from the ceiling. what does the constant red light signify?
