(2 flashes for 50 ppm CO, 4 flashes for 100 ppm CO and
8 flashes, for 300 ppm CO). When the test button is
pressed the red light flashes as per table B and also
indicates the previous CO alarm level detected. The
memory is cleared by holding down the test button until
the red light stops flashing.
Amber light flashes every 45 seconds after 6 years to
show the unit must be replaced.
