Use the MIC EC-912 to check the ionisation smoke detector's functionality before use and to support reference smoke density measurements.

The MIC EC-912 is a smoke measuring instrument for manufacturers and test teams working with ionisation smoke detectors and smoke alarms. It provides reference smoke density measurements in defined test setups, in accordance with EN 54-7 and EN 14604. 

 

When smoke density needs a defined reference

The instrument is based on the ionisation-measuring principle and uses a small radioactive source that emits alpha particles. It can be used alone or with optical smoke-measuring equipment, providing manufacturers with a defined measurement basis when detector functionality must be checked before use or when accurate smoke measurements are required in the stated test context.

Challenges

When smoke measurements are not reliable, testing cannot be completed or used for decision-making.

Functionality cannot be confirmed before testing 

If ionisation smoke detectors are not checked before testing, manufacturers lack a basis for assessing whether the detector responds correctly. 

 

Smoke measurements cannot be compared 

If smoke density is not measured consistently from test to test, results cannot be compared or used as a basis for evaluation. 

 

Delayed calibration reduces confidence 

If calibration and maintenance are not carried out regularly, confidence in smoke density measurements can decrease over time.

Benefits

Get a clear basis for smoke measurement, calibration follow-up and continued use of the MIC instrument.

Support required testing according to EN 54-7 and EN 14604

The MIC EC-912 provides a reference basis for smoke measurements when checking the functionality of ionisation smoke detectors before use. It is used in the test methods defined in EN 54-7 and EN 14604, where a defined and reproducible measurement basis is required. 

Use calibration documents in follow-up

Calibration results are presented in Pre-cleaning measurement and Certificate of Calibration. These documents provide a practical basis for reviewing instrument condition, following deviations and supporting continued use over time. 

Support continued instrument use

The recommended working life of the MIC EC-912 is ten years from the date of first use. The lifetime may be extended with proper care and calibrations, which supports continued use beyond the recommended period. 

Enable remote control of key functions

With the Intelligent MIC Control Unit, users can remotely adjust chamber voltage, run zero- and full-scale calibration before a smoke ramp and read chamber voltage through Ethernet or USB.
