Notifier FSD-751P — duct detector housing with an addressable FlashScan photoelectric smoke detector built in.
An HVAC system distributes conditioned air, and any smoke in it, to the whole building. This unit samples air passing through the duct and alarms the panel so fans and blowers can be shut down before smoke spreads through the areas the duct serves. Housing and detector come as one catalogue number; the inlet tube does not.
- Photoelectric sensing in a duct housing; 0 to 159 addresses on FlashScan, 0 to 99 on traditional
- Certified to UL 268A; 15 to 32 VDC, 300 µA standby at 24 VDC, no auxiliary supply required
- Duct air velocity 500 to 4,000 ft per min
- 32°F to 131°F, 10 to 93 percent RH non-condensing
- 14.375 in. wide by 5.500 in. high by 2.750 in. deep
- Remote test with the RTS451 or RTS451KEY, remote alarm LED with the RA400Z
An inlet tube is required and ordered separately, one per detector, sized to the duct: ST-1.5 up to 2 ft, ST-3 for 2 to 4 ft, ST-5 for 4 to 8 ft, ST-10 for 8 to 12 ft. FSD-751RP is the same unit with a DPDT relay and needs a separate auxiliary supply.
