on the detector. Entries are m ade in 24-hour format, e.g. 19 for 7pm. Day and night swi tching i s i ntended

so that the detect or may automaticall y select a different sensi tivit y when the protected ar ea is unoccupied

and fewer contam inants are being produced. Cl assiF ire automatically detects the change in sm ok e l ev el

after the protected area is left, and if the time at whic h this happens i s wit hin + 70 mi nutes of the

program med switc hover time it selects the ni ght-tim e histogram. This means that c hanges in time setti ng,

for example changing to summer tim e, may be i gnor ed as the detec tor will tak e this i nto acc ount. The

default times for day and night star t are 08:00 and 19:00 respectively.
