Report New brk 660 mbx mains powered smoke alarm beeps every 45 sec in Smoke Alarms Posted June 4, 2019 I just installed a new brk 660 mbx mains powered smoke alarm with 9v battery. The green light is on and the red light flashes every 45 sec. But it also beeps while the red light flashes. Why would it beep as it a new alarm? thanks
