instructions m ust be observed:
– Use the correct potential for activation; this is generally the potential of the
building installation.
– Only check controls up to the interface (relay with blocking option).
– Make sure that only the controls to be tested are activated.
● Inform people before testing the alarm devices and allow for pos sible panic
responses.
● Inform people about any noise or mist which may be produced.
● Before testing t he remote transmission, inform the corresponding alarm and
fault signal receiving stations.
Modifications to the system design and the products

3 Structure and functio n
The radio gateway F DCW221 is used to monitor signals from radio detectors and
to transfer them via the FDnet to a fire control panel.
The radio gateway is operated on the FDnet. All devices which can be monitored
by the radio gateway are collectively known as a 'radio detectors'.
The FDCW221 radio gateway c an communicate with the following radio detectors:
● DOW1171 radio smoke detector
● Manual call point SMF121 with radio base SMF6120
The unit, comprising radio gateway and the radio detectors logged onto it, forms a
radio cell.
The following diagram shows how the radio gateway is integrated in the fire
detection via the FDnet.

MC link
The MC link connection in the radio gateway is mainly used to connect the detector
exchanger and tester FDUD292 and the intelligent detector tester FDUD293 (as of
software V2.1). These devices allow informat ion to be read from the radio gateway
for commissioning, maintenance and troubleshooting.
You will find more information in documents 007227 and 009718.
The MC link is also used to update the radio gateway firmware. The MCL-USB
adapter FDUZ221 is used to lead the firmware from the PC to the radio gateway.
You will find a descript ion of firmware update in chapter 'Updating t he firmware of
radio gateway FDCW 221 [➙ 73]'.
For details, see document 009854.

3.1.4 Radio transmission
The radio module SPU60xx consists of a printed circuit board with two integrated
aerials.
The radio module is a module which allows for bidirectional data trans mission in
the 868...870 MHz frequency range.
The radio module has a complete send and receive unit and a microcontroller
control unit for all radio transmission funct ions.
Radio transmission takes place in the SRD band (Short Range Devic e), a reserved
frequency band with defined usage rules. The SRD band is free from amateur
users. The SRD band provides 80 channels with a channel width of 25 kHz.
Characteristics of the SRD band:
● Defined low maximum transmitting powers and duty cycle (ratio between
send/idle time)
● Sub-bands for various uses and applications
● High availability

Characteristics of the radio module:
Batteries are not included in the scope of delivery. Batteries are always needed to
● 4 alternative channels ar e assigned to each of the 16 basic channels
(5 x 16 = 80 different channels)
– If there is a problem with the basic channel, this is detected right away. If
this happens, t he frequency automatically changes channel up to four
times.
● Communication faults between the gateway and the detectors are detected and
displayed within 300 s. Alarms are transferr ed immediately.
● If a detector cannot directly reach the gateway and the contact is interrupted, a
diversion mechanism is activated. The bidirec tional contact between the
detector and t he gateway then takes place via a neighboring detector of the
same radio cell.
If the problem persists for a long time, the diversion is displayed as a fault
within 300 s, like other communication faults.
3.1.5 Reed contact and button
The Reed contact is an extra operating element which can be used to perform
some of the functions of the button when the housing cover is closed.
Generally when commis sioning, the Reed contact can also be activated with a
magnet rather than the button. Activation of the Reed contact then equates to
briefly pressing the button.
The Reed contact is act ivated by slowly pulling (approx. one second) along the
length of the Reed cont act with a magnet.

The radio smoke det ector DOW1171 works in line with the scattered light principle.
An infrared LED sends short, intense light pulses t o the scattering volume. The
orifices shield the light receiver from direct rays of light and reflexes. Penetrating
smoke particles scatter the light on the light receiver. The signal of the light
receiver is evaluated by the electronics.
Algorithms evaluate the smoke density and the probabilit ies of alarms are
forwarded by the mic roprocessor.
