[8] DH400 OE-1 Optional Accessory
General Description
The DH400 OE-1 all-weather enclosure is specifically
designed to house and protect the System Sensor model
DH400ACDCIHT high temperature duct detector from the
elements. This enclosure provides protection in outdoor
installations against rain, sleet, and snow or in indoor
installations against dripping water.
NOTE: The DH400 OE-1 is designed solely for the use
with System Sensor model DH400ACDCIHT high
temperature duct smoke detector.
Preparation
Locate the two adhesive backed gaskets packaged with the
enclosure.
NOTE: In order to provide effective sealing, these gaskets
must be placed on the outside of the enclosure
around the two large openings.
Remove the protective paper. Place the gaskets around the
large openings, aligning the screw holes of the gaskets with
the screw holes of the enclosure. Press firmly to insure
complete adhesion.
