Siemens FDCW241 Cerberus PRO Radio Gateway
The link between a Siemens FDnet or C-NET detector line and the radio detectors and call points, using two-way radio in two frequency bands.
Dealer for Siemens
Siemens Wireless Fire Detection Devices in Bhopal
Fire Protection System (FPS), a Siemens dealer in Bhopal, supplies the Siemens Cerberus PRO wireless range: the FDCW241 radio gateway, FDOOT271 and FDOOTS271 radio fire detectors and FDM273 and FDM275 radio manual call points. FPS installs, commissions and maintains them across Madhya Pradesh.
Where to use Wireless Devices
- Heritage and conservation buildings where cable runs are restricted
- Museums and churches where visible cabling would spoil the interior
- Buildings where structural reasons limit cable or conduit
- Sites that must stay in operation while the fire system is installed
- Buildings that will be changed or extended, so detectors and call points can be moved
- Extensions to an existing FDnet or C-NET addressable system
- Rooms that need a local sounder at the detector (FDOOTS271)
Siemens Wireless Devices models
Siemens FDOOT271 Cerberus PRO Neural Radio Fire Detector
A battery powered radio fire detector with dynamic signal analysis in the detector, which can be mounted anywhere within radio range of the gateway.
Siemens FDOOTS271 Cerberus PRO Radio Fire Detector with Sounder
A wireless smoke detector with an integrated sounder that sounds on a fire alarm in an addressable system, with adjustable sound level and tones.
Siemens FDM273 Cerberus PRO Radio Manual Call Point, Indirect Actuation
A battery powered radio call point with indirect actuation (break the glass, then press the button) that can be mounted anywhere within radio range.
Siemens FDM275 Cerberus PRO Radio Manual Call Point, Type A
A type A radio call point: pressing the plastic insert raises the alarm directly, and a key resets it.
How to choose
A Siemens wireless system starts with the FDCW241 radio gateway. It sits on the FDnet or C-NET detector line of the panel and talks to the radio devices both ways in the 868 to 870 MHz and 433 to 435 MHz bands. It takes power from the detector line plus a monitored 3.6 V lithium battery, ordered separately, which Siemens rates for a service life of not less than 6 years.
Then add the radio devices. The FDOOT271 is a neural radio fire detector with dynamic signal analysis, built-in diagnostics and automatic self-test, and compensation for soiling. The FDOOTS271 adds an integrated sounder with adjustable sound level and tones. Both run on a battery that is ordered separately and can be mounted anywhere within radio range.
For manual alarm, the FDM273 is a radio call point with indirect actuation: break the glass, then press the button. The FDM275 is a type A radio call point with direct actuation: press the plastic insert, then reset it with a key. Siemens lists EN 54-25, the EN 54 part for radio linked components, on all five devices. FPS can plan the radio layout with you and confirm the exact part numbers before ordering.
Frequently asked questions
Do Siemens wireless devices need a special panel?
They connect through the FDCW241 radio gateway, which sits on an FDnet or C-NET detector line. The detectors and call points then talk to the gateway by radio.
How are Siemens radio detectors powered?
By a 3.6 V lithium battery that is ordered separately. The FDCW241 gateway also uses a monitored 3.6 V lithium battery, which Siemens rates for a service life of not less than 6 years.
What does EN 54-25 mean?
EN 54-25 is the part of the European EN 54 standard that covers radio linked fire alarm components. Siemens lists it for the FDCW241, FDOOT271, FDOOTS271, FDM273 and FDM275.
Where is a wireless fire alarm system useful?
Where cables or conduit are restricted for structural, aesthetic or conservation reasons, such as museums and churches, and where work must not interrupt the building's operation.
Does FPS install Siemens wireless fire detection in Bhopal?
Yes. FPS is a Siemens dealer and supplies, installs, commissions and maintains Siemens wireless devices in Bhopal and across Madhya Pradesh. Prices are on request: call or WhatsApp +91 92440 89060.
