Are resistors required when using the Alarm.com Fire Communicator (ADC-FC100)?

The Input Trouble Supervisory circuit (NO6 and C6) will use the resistor value specified by the Fire Alarm Control Panel (FACP). Refer to the specific FACP installation guide or the panel manufacturer for this value, as it may vary from panel to panel. 

When using relay reporting, 2.2kω EOL resistors must be installed in parallel. Failure to do so will result in only generic tamper reports, rather than alarm, trouble, or supervisory signals.
