What is the PARADOX HD100 heat detector?
PARADOX HD100 is a 4-wire wired heat detector (separate power plus alarm output) supplied with a ceiling base. It sends an alarm to the panel when the temperature reaches a dangerous level and resets automatically once the cause clears, making it ideal where normal smoke or steam is common, such as kitchens and garages.
