Thermoptek advanced smoke alarm. The smoke alarm is supported by thermal sensors that increase sensitivity as temperature changes are detected. Thermoptek increases performance and minimizes problems. Thermoptek ensures functionality and protects against all types of fires. Precision optical sensors minimize error alarms. In addition, thermal sensors constantly monitor changes in temperature. If rapid temperature changes are detected, the sensitivity of the smoke alarm changes. Thanks to this, the warning is received more quickly both in fast-moving fires and in smoldering fires.
