EC5000R Reflective Beam Smoke Detector

Manufacture: kidde
Product code: EC5000R

The EC5000R ⭐
✅ comprises a transmitter and receiver in a single enclosure ⭐
✅ The transmitter emits an invisible infrared light beam that is reflected via a reflector mounted directly opposite and within a clear line of sight. The reflected infrared light is detected by the receiver and analyzed. Smoke in the beam path will reduce the received infrared light proportionally to the density of the smoke. The detector analyzes this attenuation and initiates an alarm condition when a predetermined level of obscuration is reached.

Product information

- The EC5000R System features advanced innovations such as auto-alignment, which indicates the optimal location of the reflector by means of an integrated laser. Once installed, the system automatically steers and maintains the beam to the optimum position for reliable performance.

Standard Features

• Range of 26.25 to 330 ft. (8 m to 100 m)

• Ground level controller with LCD display for easy system maintenance and testing

• Up to two detector heads reporting to one controller

• Laser-assisted prism mounting speeds installation

• Automatic beam alignment increases reliability

• Contamination compensation reduces nuisance alarms

• Building shift compensation maintains system

• Separate alarm and trouble contacts for easy configuration

• Built-in electronic UL/ULC obscuration accepted fire test

• Password protected settings for added security

• Programmable fire thresholds for application flexibility


- Reflective beam smoke detectors are ideal for large open areas such as warehouses, hotel atrium, industrial plants and school gymnasiums.

- An infrared signal is projected out of the transmitter optics to the reflector placed at the opposite end of the detection zone. The signal is reflected back to the receiver where it is analyzed for fire and trouble. The maximum lateral distance either side of the beam is found to be typically 30 feet (9.1 m) for satisfactory detection under flat ceilings, providing a total area coverage of 19,800 square feet (60 feet x 330 feet), or 1844 square metres (18.3 x 100.6 m).

- Smoke stratification may be overcome by mounting multiple beam detectors at different heights, one of which will project an infrared beam below the heat layer and the smoke layer. Detection time will be longer in a building with a peaked roof if a fire occurs at the fringes of the protected area. If in doubt conduct appropriate smoke tests.

- The ideal location and spacing of the detector is critical in a properly installed and operating fire alarm system. It is recommended that the detectors be located and spaced in accordance with NFPA 72.

- The recommended installation height is approximately 19 to 24 inches (483 to 610 mm) below the ceiling. However, in all installations the National Fire Standards for that country/state must be consulted.

- Because of the reflecting properties of the beam, all objects must be kept a minimum of 19 inches (483 mm) away the centre of the beam path down the entire beam length. If highly reflective surfaces are close to the beam, then greater clearances should be applied.
