This configuration will keep the standard occupancy CO levels below 25 ppm and the
exhaust fan will keep the average CO level below 10 ppm. If the CO levels reach 10 ppm,
and all 3 channels go into Low Alarm, OR if the CO level reaches 25 ppm and if any of the
channels goes into Mid Alarm, the exhaust fan will be turned on.
12.4.2 Time of Day Priority Example
SCENARIO:
During the time that people arrive for work and park in the underground parking
lot, you want to make sure that the CO levels are kept at a safe level and the gas detector
alarms don’t go off. People do start at different times but usually arrive between 6:30am and
8:30am Monday through Friday.
NOTE:
The priority numbers, channel numbers and relay numbers used in the examples are
arbitrarily chosen. In real life it is common to start with the first unused number and proceed
from there.
NOTE:
The time functionality uses a 24 hour clock. (ie. 9am = 9 and 1pm = 13).
In the Config Channel Menu (passcode 3022) / NEXT /

• Leave the remaining settings T2 and T3 as ###, and Logic 0
• Press Save
