Operating instructions

Greenheck 482753 Smoke Detector DUCTSD is a duct-mounted smoke detector designed to provide early warning of smoke in air conditioning or ventilation systems. It features a built-in duct smoke detector with a minimum air velocity requirement of 100 fpm and a maximum of 4000 fpm. The detector has an operating temperature range of -4°F to 158°F and a humidity range of 10% to 95%. It can be powered by 24 VAC/DC, 120 VAC (50/60 Hz), or 115 VAC.

Refer to:
‘Installation Instructions for SMD, SMDR and SSSMD
Series Leakage Rated Smoke Dampers’ (Part #461338)
or
‘Installation Instructions for CFSD Series Corridor Ceiling
Dampers’ (Part #461335)
or
‘Installation Instructions for FSD, DFD, and SSFSD
Series Combination Fire Smoke Dampers’ (Part
#481318) and FSD-3XXV series (Part # 461666) for
additional details.
Notes
1. Mininum air velocity for smoke detector operation is
100 fpm (2.5 m/s). Maximum is 4000 fpm (20.3 m/s).
2. Since the smoke detector is not rated for use at
velocities below 100 fpm (2.5 m/s), local code may
require an alternate means of damper closure such
as zone detection or automated damper closure
when the system fan is shut down. The local authority
having jurisdiction should be consulted prior to the
installation of the damper and smoke detector.
3. Holes on sampling tube must face into airstream.
4. Smoke detector specifications are:
Operating temperature range: -4°F to 158°F
(-20°C to 70°C)
Operating humidity range: 10% to 95% R.H.
Operation voltage: 24 VAC/DC or 120 VAC
(50/60 Hz)
