FDCW221
Radio gateway
Intended use
The radio gateway serves as an interface between the
radio detectors (DOW1171, SMF6120) and the FDnet. It
can communicate with up to 30 addressed radio detectors.
The radio gateway establishes bidirectional radio com-
munication with the radio detectors; the antenna is
integrated in the radio gateway. The radio gateway
consists of the following components:
– Housing bottom (see Fig. 1, [2])
– P.c.b. with radio module
– Housing cover (see Fig. 1, [1])
Openings for the feed cables can be broken out on the
housing bottom. 2 external alarm indicators can be
connected.
Preparation
1.
Open the housing. The housing cover can be unlocked
with a pin through the hole on the housing bottom (see
Fig. 1, [4]).
2.
Detach the 2 labels with the serial number from the
housing bottom. Stick one label on or into the radio
gateway, so that it can still be identified after it has been
mounted. The other label is intended for the ground
plan.
Mounting
The housing must be positioned according to the project
planning instructions (please consider good radio
propagation and accessibility). Consider a sufficient
distance to actuate the reed contact with a magnet (see
Fig. 1, [3]) and to open the housing for battery exchange
(at min. 10 cm).
1.
In the housing bottom, break out the synthetic material
for the cable entry, depending on the type of placement.
2.
Insert the cables into the housing bottom.
3.
Mount the housing bottom with 2 screws
(Ø max. 4.3 mm) on an even surface.
Electric connection
Only use cables with a wire diameter of 0.2 … 1.5 mm².
1.
Prepare the wires of the detector line; so that
later
they
can be connected to the spring clip 'LINE' (see Fig. 2).
2.
Connect the positive and negative poles of the detector
line each to a micro terminal or a connection terminal
(see Fig. 2). The detector line must be not interrupted
when it shall be tested.
Electric voltage!
Observe positive and negative poles
3.
When
shielded
cables are used for the detector line,
the shielding of the two detector line cables (incoming
and outgoing) must be connected to the spring clips
'SHIELD' (see Fig. 2). To insert the wire, release the
spring clip with a screwdriver. Only connect one wire
per terminal! The shielding must not be in contact with
any extraneous potentials or metal parts.
The shielding of the external alarm indicator cable is
connected to the positive pole of the alarm indicator by
means of a connection terminal.
4.
Do not connect the battery yet! Place the enclosed
battery connection cable and the cable ties in the
battery compartment.
5.
Make sure the housing cover engages (see Fig. 1, [1]).
For commissioning of radio gateway and for additional
