Thermocable F3051 ProReact EN analogue resettable linear heat detector sensor cable with nylon cable coating for indoor/outdoor environment. This UV resistant nylon cable coating withstands better to direct sunlight and certain chemicals. Thermocable’s ProReact EN Analogue LHD system compensates for ongoing changes in ambient temperature in order to reduce the likelihood of false alarms during operation putting it at an advantage over other linear heat detectors. Its rate-of-rise activation feature also allows for a response to quicker escalations in temperature around the sensor cable. Alarm temperature range : 54°C to 100°C. Maximum recoverable temperature : 125°C. The ProReact EN Analogue sensor cable does not have to be replaced following an alarm as long as the sensor cable is not subject to a temperature above its maximum recoverable temperature of 125⁰C. Minimum ambient temperature : -40°C. EN54-22, VdS and UL approved. It has been approved to Class A1I, A2I and BI. Roll of 200 meters
