Greenheck Fan DH100ACDCLP - Manual

Purpose/Application
National and local safety standards and codes recognize
the ability of air duct systems to transfer smoke, toxic
gases, and flame from area to area. Sometimes smoke can
be of such quantity as to be a serious hazard to life safety
unless blowers are shut down and dampers are actuated.
The primary purpose of duct smoke detection is to prevent
injury, panic, and property damage by reducing the spread
(recirculation) of smoke. The detector samples air currents
passing through a duct and gives dependable performance
for management of smoke and combination fire smoke
dampers. Duct smoke detection can also serve to protect the
air conditioning system itself from fire and smoke damage.
There are several important documents that provide guidance
concerning the performance, application and installation of
duct detectors:
1) NFPA Standard 90A, Installation of Air Conditioning
and Ventilating Systems
2) NFPA Standard 92A, Recommended Practice for
Smoke Control Systems
3) NFPA Standard 72, National Fire Alarm Code
4) NFPA Standard 101, Life Safety Code
5) UL Standard 268A, Standard for Smoke Detectors for
Duct Applications
6) ASHRAE Handbook and Product Directory, “Fire and
Smoke Control”
7) System Sensor, Guide for Proper Use of Smoke
Detectors in Duct Applications .
Duct detectors are:
NOT a substitute for an open area smoke detector.
NOT a substitute for early warning detection, and
NOT a replacement for a building’s regular fire detection
system.

Features
• Textured cover for convenient visual inspection.
• The detector provides a trouble signal in the event that the
front cover is removed.
• Integral filter system included to reduce dust and residue
effects on detector and housing, thereby reducing
maintenance and servicing.
