ESSER Systems

Connect the power supply module with four supplied spacers and use the space for installation of additional components.

The external power supply unit DB-2, built into a powder-coated metal housing, offers space for up to two 12 V / 45 Ah batteries. A connection to the fire alarm control panels IQ8Control and FlexES Control can be made directly via the optional adapter board (part no. HLSPS-ADPTR) with an esserbus® alarm tranponder (part no. 808623). Alternatively, a relay output with floating changeover contact is available for the transmission of faults (mains, battery and collective faults as well as earth fault). DB-2 offers external LED display for operation and collective fault in the lockable front door, internal LEDs for detailed detection of emergency power operation, individual monitoring of battery failure, ground fault, deep battery discharge as well as system errors and mains failure. The settings for battery capacities and combinations are made via DIP switches on the base board of the DB-2.

The adapter board is an option for the HLSPS-DB2 power supply if more than one fault relay is required. The adapter board is equipped with a relay for mains, battery and collective faults as well as earth faults. In order to connect the DB-2 to the ESSER loop, the adapter board and the esserbus alarm tranponder (item no. 808623) are required. The optional tranpsonder is plugged onto the adapter board and the power supply unit is thus integrated into the esserbus. The fault relays are designed as changeover contacts, so the relays can still be used while the esserbus alarm transponder is attached.

The esserbus transponder functions as a device on the multi-functional primary line. The connection of four zones with automatic standard detectors, manual call points (non-addressable) as well as special detectors is possible. In addition, two programmable relay outputs are also available. Both relay outputs of the transponder may be used to reset a connected third-party detector. The reset function relates to the corresponding special detector, e.g. by switching the appropriate input to GND or by a short interruption of the detectors supply voltage. Therefore, the control mode >Reset-Relay< as well as the desired relay operation mode (normally closed or open) must be configured with the programming software tools 8000 from V1.15 and above. 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 detectors manual for the required reset time.Monitoring via the EOL terminating devices (Part No. 808624/808626) is required for the connection of fire detectors and for the controlling of alarm signaling devices. The enclosed resistors can be used to connect the floating contacts. The esserbus alarm transponder requires an external voltage supply for operation of 4 monitored inputs. An optional Voltage Converter (Part No. 781336) is also required for 12 V DC operation. The esserbus alarm transponder external voltage supply can be monitored during operation. The EOL-I terminating device (Part No. 808626) must be used for standard-compliant monitoring of detector zone inputs. The EOL-O (Part No. 808624) must be used for standard-compliant monitoring of connected alarm signaling devices.

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 interface connects max. 2 industrial detectors from the UniVario product range. These detectors are supplied with energy via the 9 V DC group voltage input. For meeting the standard requirements of monitoring, an EOL-UV terminal element is connected to the detector base of the UniVario detector. The interface requires external voltage supply. Additionally, two optionally monitored relay outputs are available.
