General Description

The DH400 OE-1 all weather enclosure is specifically designed
to house and protect 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 high and low temperature limitations of the duct
smoke detector must not be exceeded. Refer to the duct detector
installation manual prior to installation.

Installation

Refer to the installation instructions of the DH400ACDCIHT for
specifications concerning placement, operating parameters, and
limitations.

Preparation

Locate the two adhesive backed gaskets packaged with the enclo­sure. In order to provide effective sealing, these gaskets must be
placed on the outside of the enclosure.

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.
