1 About this document
Goal and purpose
This document contains information required to mount the radio gateway
FDCW241.
Prerequisites:
● The installation location of the radio gateway has been established.
● Mounting should be performed by a specialist in compliance with safety
regulations.
You will find more information on the radio gatewayFDCW241 in document
A6V10227639.
Intended use
The radio gateway FDCW241 must only be used on a FDnet/C-NET detector line
in a fire detection system FS20/FS720.
● Specialist electrical engineering knowledge is required for installation.
● Only an expert is permitted to carry out installation work.
Incorrect installation can take safety devices out of operation unbeknown to a
layperson.

wYou have the radio gateway, battery pack, fixing screws, and cable tie to hand.
wYou have the device location plan to hand.
wThe connection cable has a conductor cross-section of 0.2…1.5mm².
wThe lines to the installation location are installed.
wTwo fixing screws (Ømax.4.3mm) are to hand.
1. Determine the installation location:
– The housing must be positioned in accordance with the planning
specifications (make sure there is a wide radio range and that the housing
can be accessed easily).
– Make sure there is enough space for you to open the housing cover easily.
– The housing may be installed in any appropriate position.
2. Open the housing:
– Remove the screw(2)(A).
– Using a screwdriver to press the lock(3) into the housing(B) and unlock
the housing cover(1).
– Lift the housing cover(1) and remove it.
3. Remove the adhesive label bearing the serial number from the back box and
use it to mark the installation location on the device location plan.
4. In the back box, break out the plastic for the cable entry (5):
– Openings in the supporting surface for recess-mounted cables
– Openings in the narrow side for surface-mounted cables
5. Insert the cables into the back box.
6. Mount the back box, without the battery pack, on a flat surface using two
screws (Ømax.4.3mm) at the mounting points (see
'Master gauge for recesses [➙18]' chapter). One screw at the mounting point
is sufficient for fixing in housing FDCH221.

7. Fasten the cable using a cable tie as strain relief (4).
8. Label the battery pack with the date.
9. Insert the battery pack and check the position of the battery cable. Do not
connect the battery pack until you are ready to commission the radio cell.
aThe radio gateway is installed.

2.2 Mounting in housing FDCH221
The radio gateway can be installed in a separate housing FDCH221. The housing
protects the radio gateway from dirt and dust.

1 Cable entry 4 Screws for securing the housing
2 Cables 5 Screws for housing cover
3 Screw for radio gateway
Proceed as follows to install the radio gateway in housing FDCH221:
1. Break out the required cable entries(1) on the housing.
2. Install the housing with screws(4) on a level surface.
3. Insert the cables(2). If necessary, fix the cables using M20x1.5 cable glands
or use a different cable entry.
4. Remove the housing cover from the radio gateway and dispose of it in an
environmentally-friendly manner.
5. Install the radio gateway in the housing using the fixing screw(3) provided.
6. Connect the radio gateway.
7. Close the housing using the screws(5) provided.
aThe radio gateway is now installed in housingFDCH221. The radio gateway
indicators can be viewed through the window of the housing.

2.3 Connecting the radio gateway
● Specialist electrical engineering knowledge is required for installation.
● Only an expert is permitted to carry out installation work.
Incorrect installation can take safety devices out of operation unbeknown to a
layperson.
Once all the radio devices of a radio cell have been logged on to the radio
gateway(B) in battery mode (A), the radio gateway can be connected to the FDnet/
C-NET detector line(C).

The radio gateway 'FDCW241' automatically assigns the additional, virtual address
'FDCL221v' as a line separator. When you assign the connections, you determine
the order in which the devices are read in at the control panel.
