6-46

In the case of giving more than one alarm at once, the sum of the codes of these alarms is seen
in hexadecimal form. Below are a few examples:

01 and 02 = 03

02 and 08 = 0A

01 and 04 = 05

01 and 02 and 08 = 0B

04 and 08 = 0C

01 and 04 and 08 = 0D

02 and 04 and 08 = 0E

01 and 02 and 04 and 08 = 0F

Contact with the manufacturer if these alarm codes appear.
