General

For these units, the factory installed smoke detectors are typically

installed as shown below. For horizontal return applications, the

return air sample tube is moved in the field to extend across the

horizontal opening.

For applications with a factory installed economizer, the

economizer is modified to incorporate the return air sample tube.

For field installed economizers, the installer may desire to modify

the economizer also, however, the factory modification does not

need to be replicated.
