Note: For applications in Canada that require a Desigo
Operating Unit with LEDs, Model FCM2035-U2 must be
ordered.
Desigo is ideally suited for small and mid-market
applications by providing 50, 252 and 504-point
addressable fire-alarm-control-panel (FACP). The 252 and
504-point systems are networkable.
In conjunction with these new, improved FACPs is a state-
of-the-art line of intelligent detectors. For example, the
Multi-Criteria Fire / CO Detector [with ASAtechnology
TM
] is
cutting-edge technology for specialized applications ─ such
as carbon-monoxide detection ─ compared to standardized
detectors.
The Photoelectric Smoke Detector uses microcontroller
circuitry and surface-mount technology for peak
dependability.
The ISOtechnology includes a full line of addressable
devices with optional built-in short circuit isolation.
The Desigo Model FC2025 (252-point) and FC2050 (504-
point) addressable FACP is designed to meet the fire-
protection needs of mid-size buildings.
This advanced panel offers features typically required in
mid-size buildings in a package that is easy to install and
competitively priced.
Additionally, Models FC2025 and FC2050 are networkable,
allowing the systems to fulfill the growing fire-protection
needs of the building.
Models FC2025 and FC2050 utilize a two-height-unit
enclosure.
The following components comprise a complete two-
height-unit enclosure:
▪ Operating Unit
▪ Periphery Board
▪ Power Supplies
▪ System Enclosures
Operating Interface Unit
The Operating Interface Unit (Model FCM2018-U2 or Model
FCM2019-U2) functions as the operator interfaces and
central microprocessors for the Fire Terminal (Model
FT2050) and Desigo FACPs (Models FC2025 and FC2050).
Model FCM2018-U2 or Model FCM2019-U2 provides multi-
use capability for each end-user to efficiently ‘Acknowledge’
events; to quickly control the notification-appliance circuits
(NACs) of the corresponding FACP, and to permit a manual
reset of the respective system. Detailed information about
the nature and location of the events are displayed via a
2”─x─ 4-3/4”, backlit LCD screen.
Model FCM2018-U2 or Model FCM2019-U2 contains the
site-specific program configuration created in ‘Desigo
Works’. The controller in each interface module provides all
system logic and supervision.
Either Operating Unit allows for connection to the Remote
Peripheral Module (Model FCA2018-U1) and / or the
Remote Terminal Displays (Models FT2014-U2 / R2; FT2015-
U2 / R2).
Periphery Boards
The periphery boards (Models FCI2016-U1 and FCI2017-U1)
encompass the key components for operating the Desigo
panels (Models FC2025 and FC2050). Each module
operates and monitors input-device identity; as well as
controls the signaling-line circuits that communicate with
smoke detectors and other field devices (i.e. ─ C-net).
Each periphery board is equipped with two (2)
programmable ‘Class B’ (Style Y) or ‘one (1) Class A’ (Style Z)
NAC, providing 24VDC, nominal at a 3A per circuit
maximum of audible / visual notification appliances. The
periphery boards mount directly on the enclosure back
boxes of the Model FC2025 and Model FC2050 Desigo
panels. Models FCI2016-U1/ FCI2017-U1 provide two (2)
parallel auxiliary powered, short-circuit-protected
connections (regulated 24VDC, 1.5A max) that supply
power to external devices or modules.
