Combo Smoke Heat Wireless Address Detector VIT60
Combo Smoke - Heat Wireless Address Detector VIT60 provides a reliable early warning of a fire condition, responding to fixed threshold smoke concentration or rate of rise of the temperature, or fixed temperature threshold detected in the protected premises. It combines the advantages of a type VIT30 and a type VIT20
it is an attractive option due to decreased expenses for supply and installation. The temperature class (A1R, A2R) and the smoke sensitivity (low, middle or high) are programmable by the fire control panel VIT01 and they are in accordance with the European standard EN54-5 and EN54-7.
Working Principle:
- Based on the ohmic resistance alteration in the thermistors as a result of the ambient temperature change.
- Based on the dispersion of infrared rays the smoke particles, trapped in the optical chamber.
