Introduction
The FS20 system is a life safety network that is modular, networkable fire detections system that can consist of FC2025,
FC2050 Fire control panels (250p/500p), and FT2050 Network terminal (8 lines). It comprises of all the components
required for the detection, evaluation and annunciation of life safety event such as fire and smoke conditions. By using
optional modules, copper wiring and/or Fiber Optic cables are used to network the panels together.
The FC2025 panel is capable of supporting up to 252 devices and FC2050 is capable of supporting up to 504 devices.
Both panels have a PMI with optional LED module, 2 Class B or 1 Class A NAC (expandable to 4 Class B, 2 Class A
NACs), 4 control relays, Battery Charger, Aux Power connection and optional capability for connection to Leased Line or
City Tie. Both panels support DACT, connection to Remote Printer / Remote Annunciators and Releasing Application as
optional feature. Both panels use 170W power supply or optional 300W power supply for more power capability.
The PAD-5 is an addressable booster power supply which offers additional NAC expansion with flexible configuration for
each individual circuit. The PAD-5 also includes releasing circuits and conventional zone inputs.
The FV2025 and FV2050 Fire voice control panels have all the capabilities and features of the FC2025 and FC2050 plus
voice evacuation capabilities that support Mass Notification and Emergency evacuation. Both panels have Voice Card
Cage, which, can support up to 3 amplifier circuits which, can be configured as Class A or Class B (3 primary and 1
backup, or 2 primary and 2 backup), connection LED/Switch module and optional capability for connection to remote/local
microphone, remote LED/Switch module and low-level input/output audio. It has the ability to originate and broadcast
voice announcements through connected speakers and transfer voice announcement among interconnected systems.
Both the FV2025 and the FV2050 are powered by either a single or two cascaded 300W power supplies. For Mass
Notification Application, it has the security level stated below:
- Communication Security Level 1 (Security function not employed)
- Stored Data Security Level 0 (Passwords are employed)
- Access Control Security Level 1 (Passwords are employed with programmable time-out feature)
- Physical Security Level 1 (keylocks are employed to control physical entry to the panel)
The FT2050 panel is a network terminal capable of displaying events for the entire system or can be programmed to
control and display a specific panel.
The VR2005 Remote microphone is a remote voice station that utilizes remote terminal board and can have microphone
and LED/switch modules connected to the FV2025 or FV2050 to enable fire safety personnel to originate voice
announcements remotely. The FV2025/FV2050 can power and control up to four VR2005 remote microphone stations per
node. Refer to the VTA2001-A1 installation instructions, Document ID A6V10405564, for installation information.
The FT2050 panel and remote microphone can be combined in a 2HU enclosure (2HU Remote Station) by utilizing its
respective interface units and remote switch module. Refer to Figure 5 for connection and recommended wiring routes.
The FV2025/FV2050 Voice Systems, when used in conjunction with Siemens Hi-Fidelity speakers, meets the requirement
for low frequency signal tone as described in the section for Determination of Low Frequency Signal Format, in UL464,
Standard Audible Signal Appliance, suitable for sleeping area as required by NFPA 72 Chapter 18.4.5 (2013 Edition).
Refer to Document ID A6V10333530 for compatible speakers.
The FV2025/FV2050 also supports Background music and Convenience paging functionalities using Global analog audio
input that is configured for lowest priority. Refer to the FS20 Configuration manual, Document ID A6V10315023, Section
11.6.5 and the FS20 Operation Manual, Document ID A6V10315017, Section 8.7 for proper configuration and operation.
For a complete FS20 system overview, refer to the FS20 System Description, Document ID A6V10315009.
Legacy Migration
The FC2025/FC2050 fully supports Siemens legacy systems and technology. With the use of the FCL2004-U1 module,
the Desigo Fire Safety panel offers full compatibility with legacy MXL and MXL-IQ system peripheral devices. Each Desigo
system will support up to two FCL2004-U1 modules. Each module has two ALD circuits for a total of 240 MXL compatible
devices (120 per module), in addition to the Desigo Fire Safety peripherals already available. Also available are the MXL-
IQ mechanical migration kits. The kits support existing MXL-IQ backboxes MSE-3L and MSE-3M. Reuse the existing
enclosure and replace the electronics with new Desigo Fire Safety system panel electronics.
