pied. And the only rationale for implementing this looser require‐
ment would be to avoid superfluous faults.
The 301C controller can discriminate between occupied and unoccu‐
pied duration limits this by making two outlier events (for 30 minutes
and 4 hours) and making the 30 minute event coverage period only
"Daytime". The hours of "Daytime" can be set under menu function
6. If occupancy is based on some other criterion than the time of day,
this binary condition can be accepted into the 301C controller system
by a digital input channel of a 301ADI. The event can be made condi‐
tional on the outlier and the digital input.
Note: The following requirements are from the The 2013 Nonresiden‐
tial Compliance Manual Appendix A form NRCA‐PRC‐03‐F "Enclosed
Parking Garage Exhaust System Acceptance"
Requirement: Step A 3 instructs "Temporarily override the pro‐
grammed sensor calibration/ replacement period to 5 minutes."
Solution: Reconfigure the time since calibration (TSC) event time limit
to 0 minutes. Alternatively, a stale cartridge can be temporarily
plugged into the E³Point.
Note that the 301C controller/E³Point system reports time since cali‐
bration in days. Therefore, setting the time limit to 5 minutes would
cause an event to activate 1140 minutes (1 day) after calibration.
