Safety Bus Manual — P/N LS10177-000HI-E:B 02/21/2019 36SB-ECM Module System Components3.7 SB-ECM ModuleThis module can control an automatic extinguishing/release system. The module controls eight (8)supervised inputs with safety-related functions, four (4) safety related supervised outputs to controlsolenoids, two (2) non-safety related supervised outputs to control notification appliances and one(1)virtual output V15, used to activate the automatic release sequence in embedded mode or as aninternal variable in I/O mode. As to the 8 input channels, the first six are suitable for NO/NC con-tacts with a max line current of 40mA, while the last two channels are suitable for controllingNO/NC or conventional smoke detector contacts with a max line current of 130mA. As for the 6output channels, the first four channels are suitable for controlling solenoid valves or visual/acous-tic signals with a max current of 500mA and safety-related functions, while the last two channelsare regulate NAC outputs with a max current of 195 mA.Note: Synchronization of devices between zones or within a zone is not permissible using this mod-ule.3.7.1 Technical Specifications• Number of input channels: 8 individually configurable• Wiring:– Inputs Class B, Style B and Style C– Outputs (NAC) Class B, Style Y– Outputs (REL) Class B• Alarm threshold for input channels 1-6: 2 programmable thresholds from 4 to 35mA• Alarm threshold for input channels 7-8: 2 programmable thresholds from 4 to 120mA• Short circuit threshold for input channels 1-6: programmable from 4 to 40mA *• Short circuit threshold for input channels 7-8: programmable from 4 to 131mA *• Open Circuit threshold for input channels 1-8: ≤1mA• Input channel test: performed every 30 seconds• Max current for output channels 9-12: 500 mA• Short circuit threshold for output channels 9-12: current >0.75-1.5 A• Open Circuit threshold for output channels 9-12: current <0.5-9.5 mA• Channel test for outputs 9-12: performed every 3 seconds• Max current for output channels 13-14: 195 mA• Max.
