Exigo Overvoltage Protection 2x 100V/70V lines
In order to comply with the strict rules of EN54 it is mandatory to use overvoltage protection on the speaker lines.
The diagram shows how the overvoltage protection (F21) is wired.
Exigo Overvoltage Protection 3x I/O lines
In order to comply with the strict rules of EN54 it is mandatory to use overvoltage protection when interfacing with external system using the control input(s).
The diagram show an example on overvoltage protection (F20) on the control inputs:
- Control inputs 1 and 2 are local buttons located inside the rack. These do not need protections since they are not interfacing to any external system.
- Control inputs 3, 4 and 5 are interface to the fire alarm system. They need to have overvoltage protection since they are interfacing external systems.
Surge Protection - 230VAC
In order to comply with the strict rules of EN54 it is mandatory to use surge protection on the 230VAC.
The diagram shows an example on how to wire the surge protection (F10).
