WES3 Heat Sensor

Early warning of abnormal heat to pre-warn of potential fires

WES3 heat sensors are an integral part of the system, providing essential detection in and out of working hours on all types of projects. Unlike smoke sensors that detect the presence of smoke particles, heat sensors only react to changes in temperature. The sensor work in the radio mesh network to transmit and receive radio messages from other units to help site-wide radio performance. Thermistor technology registers changes in temperatures and, if necessary, activates the alarm. With 4G functionality means your site is protected 24 hours a day, seven days a week.
