 transponder Special detector (SD) (Part No. 808623.40) 
To connect special detectors and related reset functions with pre-alarm, fault and alarm assessment. The 
transponder can be adapted to the different reset behaviours of the connected special detectors.  
The inputs and outputs of the transponder can be connected with one another in such a way that switching on / 
resetting a signalling input leads to short-term activation of the special detector’s reset input. In order to support 
various special detectors, the transponder’s inputs can be programmed with a suppression time of up to  
255 seconds when resetting. 
 
•  4 detector zone inputs 
•  Conventional connection of special detectors 
•  2 programmable relay outputs for resetting the special detector with 
flexible reset times 
•  Integrated loop isolator 
•  Loop monitoring acc. EN 54-13
