How the system works

A problem of outdoor alarm systems is unwanted reactions (false alarms) to phenomena having nothing to do with an intrusion attempt.
MICMAR uses optical fibres both as a sensor and transmitter of alarm signals. Optical fibres are made of glass and light travels inside them. Optical fibres, and consequently the MICMAR system, are not affected by external sources of disturbance.
MICMAR uses the principle of optical signal attenuation (decrease in the quantity of light beyond a certain preset threshold) to generate an alarm.
Whenever an intrusion attempt occurs the MICMAR system activates the SENSOR UNIT, which creates a mechanical deformation on the Sensorproof cable, thereby increasing the level of optical attenuation. The latter is evaluated, filtered and converted into an alarm signal by the FOSE PLUS microprocessor control unit.
With its optical/mechanical system, MICMAR has developed 100% reliable perimeter alarm protection, with no risk of false alarms.
Each sensor unit has a cover with an alarm to prevent tampering and opening.
