The use of analogue information provides significant benefits to the end user, installer and serviceman in ways which are not possible with a conventional type system. Since this detector is also addressable, it will help to quickly locate a fire during its early stages. The MI-FHSE and MI-HTSE are fixed temperature analogue addressable sensors employing low mass thermistors and microprocessor technology for fast response and linear temperature sensing. Their linear response allows these sensors to be used to signal temperatures over the range of 58A C (Class A1S) to 78A C (Class BS).
