Question:
Home alarm system - is temperature sensor a good fire prevention?Is monitored temperature sensor an effective fire prevention device? Or is it just a incident report device?

Answer: -I might consider the use of a heat detector IN ADDITION TO a smoke detector, as a backup, but never instead of. Even the manufacturers of heat sensors say this. For instance, http://www.masterguard.com says: "NOTICE: Properly functioning smoke alarms give earlier warning than Heat Alarms in nearly all residential fires. This is because detectable levels of smoke almost always develop before detectable levels of heat."

-To my knowledge the only *prevention* is to use inert gas. For example: http://www.minimax.de/en/produkte/gassysteme/permatec/ Everything else just alerts/reports: A temperature sensor is a great thing to detect fires without smoke so if you are sure that the only thing caching fire in your house can be your stored liquor (ethanol) the heat sensor will be best. Or under very special cirumstances [do you store dipropylmethane? Multicriteria (optical + ionsisation + heat). In any other case use multicriteria (optical + heat) sensors.
