Product Description

Air Products and Controls 55000-335DCT is a photoelectric replacement smoke detector head for SM-501 series duct smoke detectors. It supports 24 VAC, 24 VDC, 115 VAC and 230 VAC operation, provides dust filtering and includes a standard exhaust tube for HVAC duct sampling. The head is rated for duct widths from 6 in. to 10 ft. and air velocities of 500 to 4000 fpm, and is compatible with building automation and fire alarm systems.

  • Supply voltage: 24 VAC, 24 VDC, 115 VAC, 230 VAC; frequency 50/60 Hz; standby and alarm currents specified per voltage
  • Designed for duct use: duct width 6 in. (15 cm) to 10.0 ft. (3.05 m); air velocity 500–4000 fpm (2.5–20.3 mps); includes dust filtering and standard exhaust tube
  • Integration features: two alarm relay contacts (2-SPDT, 10A @115 VAC resistive), one trouble contact (1-SPDT, 10A @115 VAC resistive), interconnectable up to 30 detectors

Product Highlights

Photoelectric duct replacement head for SM-501 series with universal voltage support, dust filtering, specified duct/air velocity range, and relay contacts for fire system integration.
