Bus input/output module for connecting wired detectors (NO/NC) or alarm lines with up to 500 mA 38 V switching outputs to the bus of the 9000 system. The inputs can be connected to NO/NC magnetic contacts, motion detectors, or mechanical contacts. Each alarm line can be assigned its own response, such as fire, flooding, or burglary alarm. The wiring of an alarm line can optionally be done via single or double resistor monitoring with adjustable resistance values of up to 10 kOhm, allowing for easy retrofitting of existing systems. An integrated measurement tool for resistance values enables comfortable diagnostics of the alarm lines. By default, the outputs respond to the switching outputs up to the control panel. The assignment can be changed via software, and combinations of switching outputs are also possible. A load of 500 mA 38 V can be switched potential-free across all outputs. Power supply for external devices: 12 V DC, maximum 200 mA. Can be installed in the 9000BD12 mounting box or directly in the control panel. Occupies addresses in the 9000 system upon registration. Operating voltage via bus, standby current consumption: 11 mA with all inputs grounded, I-calc = 26 mA, including 10 pieces of 1 kOhm resistors, operating temperature -10 °C to 40 °C, dimensions: 77 x 40 x 31 mm. 9000EA4.
