Treat yourself to the ESSER 808623 ESSERBUS alarm transponder at the best price.

The Esser 808623 esserbus transponder works as a device on the multifunctional primary line. The connection of four zones with automatic standard detectors, manual triggers (not addressable) as well as special detectors is possible. In addition, two programmable relay outputs are also available. The two relay outputs of the transponder can be used to reset a connected third-party detector. The reset function affects the corresponding special detector, e.g. by switching the appropriate input to GND or by briefly interrupting the supply voltage of the detectors. 

Therefore, the Reset-Relay control mode as well as the desired relay operation mode (normally closed or open) must be configured with the 8000 programming software tools from V1.15 and higher. The relay output will be activated for the selected reset time (1 to 14 seconds) if the assigned input (G1 for relay 1 / G2 for relay 2) of the transponder is reset. Refer to the manual of the detectors for the required reset time.

Monitoring via EOL termination devices is required for the connection of fire detectors and for the control of alarm signalling devices. The included resistors can be used to connect floating contacts.

The esserbus alarm transponder requires an external power supply for the operation of 4 monitored inputs. An optional voltage converter is also required for 12 V DC operation. The external voltage supply of the esserbus alarm transponder can be monitored during operation.

The EOL-I termination device must be used for standard-compliant monitoring of the detector's zone inputs. The EOL-O is to be used for standard monitoring of the connected alarm signalling devices.

It is an input/output device with 4 inputs and 2 outputs for the connection of 4 non-addressable detection zones on esserbus or esserbus-Plus.
