Leased line/city tie mod. – This is the connection of FACP to the Leased Line or City Tie through optional LLCT Module
(FCI2020-U1). This is configured as Class B only and is supervised only when configured as City Tie. Refer to the FS920
Mounting, Installation and Product Data manual, Document ID A6V10333409, Section 23, for proper wiring connection.
Central/Remote Station – The FACP uses the Dialer module (DACT) (FCA2015-U1) connected to the PSTN to connect to
the central or remote station in the event of life safety situation. Connections to phone lines are supervised. Refer to the
FS920 Mounting, Installation and Product Data manual, Document ID A6V10333409, for proper wiring connection.
For Canadian Installations, the following applies:
- Both the Dialer module (DACT) (FCA2015-U1) and the 3
rd

to the same Central Station.
- One of the User-Defined buttons on the Operating Unit must be programmed as
Manual Alarm Signal
(evacuation) Control, which
is able to initiate alarm signal and resound audible devices after they have been
silenced. The button chosen must be clearly marked on the Inscription Strip.
- The Battery disconnect module (FCA2032-U1) is required to disconnect the battery when voltage drops below 19
VDC while system is on battery power.
- If using an Remote display/Remote terminal (FT2014-U3 or FT2015-U3) the Inner Door RDT (black) (FHD2012-
