alarm when exposed to constant levels of 30 PPM for 30 days. It will alarm at the
following levels: 400 PPM CO between 4 and 15 minutes, 150 PPM CO between 10
and 50 minutes and 70 PPM CO between 60 and 240 minutes.
7. The unit shall have an “End of Life” signal. This signal should be capable of
temporarily being silenced for up to 2 days. After about 2 days, the signal will
resume. After about 2-3 weeks the signal cannot be silenced.
