Smoke Detector
Locate in a normally occupied area of premises. Recom-
mended for compliance to NFPA-90A and IMC code 606.
HRVs can be equipped with a duct mount smoke detector
which will monitor the air when passing through the duct
system into the HRV. When sufficient smoke is detected,
an alarm condition is activated. By connecting the occu-
pied timer/sensor contacts to the NC alarm auxiliary con-
tacts on the duct sensor, an alarm condition will open the
auxiliary contact and stop operation of the HRV.
