Product Overview
Model FCI2020-U1 is used as an optional
module, giving a local-energy output for
municipal call-box connections. Additionally, a
leased-line / city-tie module provides reversepolarity output for leased-line connections.
Model FCI2020-U1 is installed on the 252-point
(Model FCI2016-U1) and 504-point (FCI2017U1) periphery boards, respectively, but is
installed on the back of the main board (Model
FCM901-U2) used with Desigo 50-point
addressable panels.
When an optional leased-line / city-tie module is
used on Desigo 50-point panels, a wiring harness
(Model FCA901-U1) must be ordered separately.
When used for connection to a municipal call
box, the city-tie function supports Alarm-event
transmission.
When used for leased-line
connection, the module supports two (2) leased
telephone lines for transmitting Alarm, Trouble
and Supervisory system events.
The Leased-Line / City-Tie Module is FM (#3010); CSFM
(#7165-0067:0259), and FDNY (#6104) Approved.
Additionally, the programming software is held in flash
electrically erasable programmable read-only memory
(EEPROM).
Temperature and Humidity Range
Model FCI2020-U1 is UL 864 9th Edition Listed for
indoor dry locations within a temperature range of 120
+/- 3°F (49 +/- 2°C) to 32 +/- 3°F (0 +/- 2°C) and a relative
humidity of 93 +/- 2% at a temperature of 90 +/- 3°F (32
+/- 2°C).
