The 1142-000 ceiling mount positions Kidde EC-50R and EC-100R reflective beam smoke detectors at the recommended 19 to 24 inches below the ceiling, per NFPA 72 spacing guidelines. Stem-and-backbox design drops the detector to the correct height in warehouses, atriums, industrial plants, and gymnasiums without custom fabrication.
Built for beam detector installs in high-ceiling spaces
Reflective beam detectors protect large open areas where spot detectors can't reach. The 1142-000 mounts the EC-50R or EC-100R at the correct distance below the ceiling and provides a stable platform for reliable beam alignment. Beige finish blends with standard commercial ceiling grids.
Key features
- Purpose-built for EC-50R/EC-100R: positions the detector at the NFPA 72 recommended 19-24 in. below ceiling
- Stable mounting platform: reduces detector movement that causes false trouble conditions from beam misalignment
- Beige finish: blends with standard commercial ceiling grids and structures
- Complete assembly: ceiling plate, stem, and mounting backbox included
Compatible detectors
Supports the Kidde EC-50R (15-160 ft range, single reflector) and EC-100R (160-330 ft range, four-reflector group). Both models operate on 24 Vdc from the fire alarm control panel and use a 4-wire connection. The mount positions the detector; reflectors mount separately on the opposite surface with clear line of sight.
