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).
The surge protection are connected to the AC Main input. This way the battery charger, ESC1 Controller and ENA2200 amplifier will all be protected by the surge protection (F10).
Surge Protection - 48VDC
In order to comply with the strict rules of EN54 it is mandatory to use surge protection for the ENSER-8 switch and the IEM-3000-4PC PoE module (48VDC).
The diagram show an example on how to wire the surge protection (F11).
The ENSER-8 switch and the IEM-3000-4PC PoE module gets power from the same output on the battery charger.
The surge protection is connected to the same output and will protect both the ENSER-8 switch and the IEM-3000-4PC PoE module.
SPA-REL-V2
In order to comply with the strict rules of EN54 it is mandatory to use SPA-REL-V2 on the control outputs.
The diagram show an example on how to wire the SPA-REL-V2 (R1, R2 and R3).
The control output 1, 2 and 3 on the ESC1 controller are protected by individual SPA-REL-V2.
It is also recommended to use SPA-REL-V2 even if the installation is not EN54.
System Fault
In order to comply with the strict rules of EN54 it is mandatory to have system fault visibly indicated.
From EN54-16:
8.5 System fault
a) a system fault shall be visibly indicated by means of the general fault warning indicator and a separate light emitting indicator on the VACIE.
This is achieved by using a control output and a external LED for indication of system fault on the ESC1.
