Potter PAD200-DD — the photoelectric duct smoke detector head fitted inside a Potter PAD200-DUCT or PAD200-DUCTR housing.
This is the sensing head, not a complete duct detector. Potter names it in both duct data sheets as the Detector Head Model, and each engineering specification requires a detector base and a PAD200-DD head in the housing.
- Detector head type: photoelectric, with a self-diagnostic sensitivity test method
- Fixed alarm set point of 2.5%/ft. in the duct assemblies it is used in
- Host assemblies run at 24 VDC and draw 300 µA (PAD200-DUCT) or 500 µA (PAD200-DUCTR)
- Rated air velocity 100 to 4,000 ft./min., 32 °F to 120 °F
- Potter IPA and AFC/ARC addressable panels, addressed 1 to 127 by a seven-position dip switch
- Housings are UL 268A certified and UUKL certified for smoke control, SLC Class A, X and B
Order the right thing: PAD200-DUCT (stock 3992792) is the complete duct detector and PAD200-DUCTR (3992793) adds one Form C relay rated 8 A at 30 VDC and 10 A at 120 or 250 VAC. Sampling tubes are never included; STN-2.5, STN-5 and STN-10 are separate numbers chosen by duct width.

FAQ
Is this a complete duct detector?
No. The PAD200-DD is the photoelectric detector head that goes inside the PAD200-DUCT or PAD200-DUCTR housing.
Are sampling tubes included?
No. An exhaust tube is supplied with the duct housing, but the intake sampling tube is ordered by duct width in 2.5 ft, 5 ft or 10 ft lengths (STN series) and cut to fit.
What air velocity is it rated for?
100 to 4,000 ft per minute, at 32°F to 120°F.
Which panels does it work with?
Potter IPA and AFC/ARC series addressable panels.
