Greenheck Fan Smoke Alarm DH100ACDCLP User Manual

DUCT SMOKE DETECTOR  
DH100ACDCLP  
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.  
Configuration  
Maximum wall thickness: 6 in. (152mm) on FSD & SSFSD  
applications  
(Consult factory for walls greater  
than 6 in. [152mm])  
Specifications  
Type: Photoelectric  
Air duct velocity: 100 to 4000 fpm (.5 m/s to  
20.3 m/s)  
Actuator Location: Must be right hand drive  
Must be externally mounted  
Operating temperature range: 32°F to 131°F (0°C to 55°C)  
Operating humidity range: 10% to 93% R.H.  
Operation Voltage: 24 VAC/DC or  
120/240 VAC  
Detector Location: Mounts opposite actuator side  
Must be external  
Sampling tubes longer than three feet must be supported  
on each end. Holes in duct smoke detector sampling tubes  
must face into the airflow.  
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.  
Availability  
For use with all FSD, SSFSD, SMD, SSSMD, and CFSD  
models. Not available on SMDR models.  
Terminal connections are of the strip and clamp method  
suitable for 12-18 AWG wiring.  
Listings  
• Outside mounting tabs for easy connection to sleeve or  
ductwork (when detector ships loose).
