b) Disconnection switches These switches cut the power path of the power supply and the battery. They help to avoid the danger of sparks when connecting the battery and it's useful for restart the equipment completely. 2.2.2 Battery installation Before installing the battery it is recommended to switch off the equipment using the switches in the supply circuit. - Page 11 Illustration 7: Supervised CIE connection Illustration 6: Fire Central Interface Connection is made using female euroblock connectors given with the equipment. The → → cable section range for each pole of this connector is: 0,14 1,5mm2 (30 14 AWG). Inputs are activated when the dry contact is voltage free. (N.O.= normally open) a) Zone emergency activation inputs These inputs are connected the same way as the general entrance to allow link supervision.

They allow a maximum current of 350mA and a voltage of 350V. d) RS-485/MODBUS Interface Communication port on RS-485 half-duplex base for communication with fire control panel. It needs to be connected by 2 twisted wires (A, B) plus a GND wire. The port uses protocol MODBUS RTU and is used to connect a fire central with advanced commands. -
Page 13: Audio Source Inputs
2.2.5 Audio source inputs The system integrates 3 inputs for background music and/or microphones. See the audio inputs configuration for further details. At the side of each input there is a luminous audio signal indicator that activates with signal over -40dBV. The audio input connection is made by euroblock connectors that allow cable sections →... -
Page 14: Link Output
The ACSI input integrates audio, communications and power allowing the emergency devices to be fed directly from the integrated backup source. The connection is made using standard UTP network cable T568B. The connection is made by bus, with a maximum connection length of 1000m. This input has a signal indicator LED for audio tests and a state LED that will indicate that there are connected devices. - Page 15 b) USB USB connector A type external memory connection (MEMORY- STICK) that allows import messages, actualize firmware and import and export configurations Logs. c) Expansion bay This connector us an expansion bay expected for future system ampliations. Its future options will be to provide simple redundant...
