In order for the return air smoke detector to properly sense
smoke in the return air stream, the air velocity entering the
unit must be between 500 and 4000 feet per minute.
Notes:
•
Airflow through the unit is affected by the amount of
dirt and debris accumulated on the indoor coil and
filters. To insure that airflow through the unit is
adequate for proper sampling by the return air smoke
detector, complete adherence to the maintenance
procedures, including recommended intervals
between filter changes and coil cleaning, is required.
•
Periodic checks and maintenance procedures must be
performed on the smoke detector to insure that it will
function properly. For detailed instructions concerning
these checks and procedures, refer to the appropriate
section(s) of the smoke detector Installation and
Maintenance Instructions provided with the literature
package for this unit.
Important:
Refer to the service literature provided for
testing and other information about the
smoke detector or if problems are
encountered.
