esserbus transponder for special detectors


For connection of special detectors and associated reset functions with evaluation of pre-alarm, fault and alarm. The transponder module can be adapted to the different reset behaviour of the connected special detectors. The inputs and outputs of the transponder can be linked together in such a way that switching on or resetting a signal input leads to short-term activation of the reset input of the special detector. In order, to support various special detectors, the inputs of the transponder can be programmed with a suppression time of up to 255 seconds at reset.

The transponder can only be operated via FlexES Control with the above mentioned features. With IQ8Control panels, the loop device behaves like an Alarm transponder. Minimum requirements: Tools 8000 ≥ V1.25R000 FlexES Control ≥ V4.07R000 (Container V1.06)
