GSA-DH is the Kidde intelligent duct smoke detector housing for Signature Series detectors. It holds a standard Signature smoke detector and base, so no special duct head is needed. Air moving in the duct enters through the perforated inlet sampling tube, passes the detector, and leaves through the exhaust tube; the inlet must be upstream of the exhaust.

Compatibility and installation notes
- Supplied with a 6 in. (150 mm) exhaust tube, gaskets, installation instructions and a self-adhesive drilling template.
- Order separately: one detector (GSA-PS, GSA-PHS or GSA-IPHS), one base (GSA-SB standard, GSA-RB relay or GSA-IB isolator), and one inlet sampling tube: 73681-1 (8 in.), 73681-2 (24 in.), 73681-3 (42 in.), 73681-6 (78 in.) or 73681-10 (120 in.).
- The sampling tube must span the full duct width; tubes longer than 3 ft. (900 mm) must be supported at both ends.
- Needs a clear, flat area on the duct of at least 7-3/8 in. W x 7 in. H. Test duct air velocity before installing; duct humidity must be 0 to 93%.
- Accessories: GSA-LED remote alarm LED (with GSA-SB base only), GSA-DTS duct test station, 6263-SG air velocity test kit.
- Duct detectors are not a substitute for open area smoke detection.
