The product is made  accoding to EN54 .

It is avaible for convential type & addressable type.

The SY-AD800 is an analogue addressable rate of rise

heat detector. It will respond with a value of 75 if the

detector is triggered by a rate of rise alarm (that is a

fast increase in temperature over a set period of time).

The detector also responds to a fixed temperature of

57°C and will return a value of 95 if the detector is

triggered by this condition.

 

The SY-AD800 is an analogue addressable fixed

heat detector. It will respond with a value of 95 if the

detector is triggered through a fixed heat alarm of 90°C.

 

Heat detector  SY-800 operates by utilizing a matched pair of thermistors to sense heat. One of these thermistors is exposed to the ambient temperature, while the other is sealed inside the detector housing. Under normal conditions, both thermistors register similar reading. As fire happened, the temperature registed by the exposed thermistor will rise rapidly, resulting in an imbalance, causing the detector to go into its alarm suitation.
