Connection of polarized devices (sounders, etc.) to channels configured as outputs
brown, black, red
The polarities refer to the active status of the output, the polarities invert for stand-by status.
EN54:
If the control panel default settings are left unchanged, the I/O 1 output will result as being configured as
a type C output for the connection of audible/visual signalling devices.
The output will activate in the event of any type of fire-alarm condition.
Connection of non-polarized devices (relays, etc.) to channels configured as outputs
brown, black, red
1N4007 diodes
The polarities refer to the active status of the output, the polarities invert for stand-by status.
Connection of devices with an alarm output to channels configured as input
The wiring diagram illustrates a connection made to one of
the "I/O" channels [A], configured as input. The connected
