Factory replacement prismatic reflector for the Kidde EC-50R and EC-100R reflective beam smoke detectors. The reflector mounts opposite the detector head and returns the infrared beam to complete the detection path. When the original reflector is damaged, misaligned beyond recovery, or missing, this drop-in replacement restores the system to listed operation without replacing the entire detector assembly.

Built for the fire alarm installer

P/N 23901-01 is the Kidde-specified replacement for both the EC-50R (16-50 ft range) and EC-100R (16-100 ft range). Using the factory-listed reflector keeps the system within its UL and ULC listings - no inspector questions, no approval headaches. Mounts on the wall surface directly opposite the detector head at the same height.

Key details

  • Direct factory replacement for both EC-50R and EC-100R beam smoke detectors
  • Prismatic retroreflective design returns the IR beam to the detector head across the protected space
  • Maintains UL/ULC listing of the installed beam detection system
  • Wall-mount installation opposite the detector at matching height - alignment is critical for reliable detection

FAQs

Does this reflector work with both the EC-50R and EC-100R?
Yes. P/N 23901-01 is the factory replacement reflector for both the EC-50R (16-50 ft range) and EC-100R (16-100 ft range) reflective beam smoke detectors.
Where does the reflector mount?
The reflector mounts on the wall directly opposite the beam detector head at the same height. The infrared beam travels from the detector to the reflector and back. Proper alignment is critical for reliable smoke detection.
Can I use a third-party reflector?
Kidde specifies P/N 23901-01 as the approved replacement reflector for the EC-50R/EC-100R system. Using a non-listed reflector compromises the UL/ULC listing and may not return the beam reliably across the full detection range.
What is the maximum detection range?
Depends on the detector model. The EC-50R supports 16-50 ft (5-15 m) and the EC-100R supports 16-100 ft (5-30 m) between the detector head and this reflector.
