Smoke Detector Testing/Calibration

Smoke sensor is a measuring device and it is most vulnerable to lose sensitivity. Reduction of sensitivity happens due to various reasons, therefore it has to be calibrated periodically. We offer testing and calibration services for various brand smoke detector.

As per NFPA 72 e chapter

Any of the following tests shall be performed to ensure that each smoke detector is within its listed and marked sensitivity range.

  1. 1) Calibrated test method.
  2. 2) Manufacturer’s calibrated sensitivity test instrument.
  3. 3) Listed control equipment arranged for the purpose.
  4. 4) Smoke detector/control unit arrangement whereby the detector causes a signal at
        the control unit when its sensitivity is outside its listed sensitivity range.

Our calibration service extends following benefits to the user
  1. 1) To keep the fire detection system healthy.
  2. 2) Enable To Buy right detector and avoids spurious detector.
  3. 3) Helps to dispose derated detectors.

Always buy detectors which has good sensitivity.

High sensitive and wide range sensor has more advantage few are
  1. 1) Detects smoke early, safety increases proportionately.
  2. 2) Life of detectors chances are more

Periodically test and calibrate the detectors to ensure sensitivity is maintained. Ensure your AMC contractor does this exercise. Ensure your detector supplier offers calibration service at your country.

Efficiency of the Detector:

The efficiency of the detector is proportionate to its sensitivity. Before choosing the detectors check the sensitivity of the detector which is mentioned at manufacturer's technical datasheet.
