Connection to FACP Dry Contacts
The dry contacts of the FACP programmable relays can be used to trip a UL-864 Listed Central

Remote Station Transmitter module using End-of-Line Resistors (ELRs) with a value determined
by the Transmitter manufacturer. Power is also provided by the Central Station/Remote Station
Transmitter manufacturer. Refer to the Central Station/Remote Station Transmitter manufacturer’s
manual for details.
