1. General Information
The RDD2 radio channel magnetic contact sensor (hereinafter referred to as the
device) is designed to be used as an opening sensor (reed relay). The device generates
alarm signals for sensors, additional ribbon cables, enclosure break-in, and transmits
them to the control panel.

8. Device: Getting Ready for Operation and Adding to Radio System
8.1. Place a device on a fixed surface of a door or window opening at least 1 m from
the receiving radio channel device. Install the mating piece to the window frame
or door.
Do not place the device in the vicinity of EMI sources, large
metal objects and structures, power cable runs!
8.2. Open the enclosure.
8.3. Install a battery and close the cover.
8.4. After closing the device cover or installing the battery, the device switches to
battery test mode, signaled by the red indicator turning on for 2 seconds. If the
battery had not been in use for a long time, it depassivates. The red indicator
lights up in series of flashes illustrated in the figure below up until the moment
the battery goes into the normal operating mode. If a battery remains in this
mode for longer than 15 minutes, it is recommended to replace it.

After testing a battery (the battery now operates at its normal voltage), the red
indicator will light up for 4 seconds, and then the green indicator lights up for 1
second.
If the depassivation has not been performed, the red indicator lights up for 2
seconds, after which the green indicator lights up for 1 second.

The battery is tested each time the device cover is closed!
8.5. If the red indicator emits short flashes twice in 5 seconds (not to be confused
with the battery test mode), this means the battery is depleted and needs to be
replaced.
8.6. Switch the device to the mode of addition to a radio system (see Paragraph 6).
Add the device to the control panel radio system according to the radio system
instruction. The distance between the device and the receiver should be at least
1 m. The device then receives settings from the control panel. The addition
process is illustrated in the diagram:

8.7. Switch the device to the radio channel test mode (see Paragraph 6).
8.8. Make sure the message exchange quality is strong in the supposed installation
location by referring to LED indicators. 2–3 missed responses are OK for 10
transmitted messages:

8.9. If an additional alarm wire loop is used, insert the ribbon cable and connect it to
the XT1.
8.10. Put corresponding wires in slots and secure the enclosure base on the surface.
An enclosure tear-off tamper is installed by default.
8.11. Switch the device to the standby mode (see Paragraph 5).
8.12. Verify the signal path for alarm signals of the sensor, tamper, and, if necessary,
additional alarm wire loop by referring to LED indicators.
8.13. Install the mating piece (magnet) not further than 10 mm away from the SA1 reed
relay. If necessary, use backing plates.
8.14. The device is ready for operation.
9. Hardware Reset to Factory Settings
Remove the battery from its holder, install the JMP1+JMP3 jumpers, and place the
battery back. This procedure is shown in the diagram:

The radio signal strength between the device and the control panel is
determined by the level of signal attenuation, which can be seen in the radio
channel security and control panel configuration software, page Radio Device
Map. For more information please refer to the control panel user manual.

10. Replacing Battery
If necessary, clean the bonding pads and replace the battery. When replacing a
battery, close the battery contacts for 2 seconds and then install the new battery.
11. Transportation and Storage
The device should be transported in packaging in closed vehicles. Storage premises
should be free of current-conducting dust, acid and alkaline fumes, corrosive gases and
gases harmful to insulation.
12. Maintenance and Safety Measures
All setup and maintenance activities applied to the device should be performed by
duly qualified personnel.
13. Manufacturer’s Warranties
The manufacturer guarantees that the device complies to requirements of the
technical specifications, provided the client ensures compliances to conditions of
transportation, storage, installation and operation.
Although the warranty period is 12 months from the commissioning date, it may not
exceed 18 months from the production date.
The warranty storage period is 6 months from the production date.
The warranty does not cover the battery.
The manufacturer reserves the right for modification of the device in any way that
does not degrade its functional characteristics without prior notice.
14. Information on Claims
In case of a device failure or defect during the warranty period, please fill in a
malfunction report specifying the dates of issue and commissioning of the device and
nature of the defect and submit it to the manufacturer.
