  1. I had Ei140RC series fitted February 2018. All new units. All new batteries. On one unit, the red light currently flashes twice every 40 seconds, instead of once every 40 seconds. This particular alarm was also beeping three times (not chirping) intermittently over night, at about 3am. I vacuumed around the alarm using the soft brush attachment of the vacuum cleaner; it didn’t beep again, but still it flashes red twice, instead of just once. Green light is solid and there's been no recent power cuts. Can anyone help please; dreading being woken again tonight!
