Extra COM terminals are provided for wire monitoring or EOL resistors.
Fault relay is continuously activated when detector is normal.
The fire and fault relays can be used as either normally closed or normally open contacts. The contacts are selected
by fitting links to CON4 and CON5 on the terminal board. The links must be fitted for the output to operate.
Other options can be used at the same time as the Relay output.
