6. Adjust the DIP switch settings on the base (Fig.
r
). See the
“
Setting the range and lock-out time” instructions.
7. If you need to place the enclosed stickers onto the mirror in
order to mask the mirror, unscrew the base from the front
cover (Fig.
s
A) to access the mirror (Fig.
s
B & C). See the
“Selecting the coverage pattern” section.
Caution!
Removing the stickers can damage the mirror
surface.
8. Replace the unit onto the mounting plate (Figs.
t
A and B).
9. Carry out the remaining installation tasks (explained in the
following sections):
A. Setting the range and lock-out time
B. Walk testing the detector
C. Selecting the coverage pattern
D. Setting up the transmitter
10. When all the installation tasks have been completed, screw
the detector on the mounting plate by removing the custom
insert and inserting the screw. Replace the custom insert
(Figs.
t
C & D).

Note
: Range reduction will reduce PIR sensitivity in the
undercrawl area.
Detector range:
The microwave and PIR ranges can be individually selected
between 7.5 ±0.5 m and 12 ±0.5 m using DIP switches 1 and 3
respectively.
PIR only / Dual mode:
PIR-only mode:
Consequently the microwave circuitry is switched
off and the detector will only signal alarms caused by the PIR
circuitry.
Dual mode:
In dual mode the detector will signal an alarm when
both technologies (microwave and PIR) have identified a target
moving in the protected area.
Lock-out time:
This is the detector ’s standby time. It occurs just after the
detector has sent an alarm via the wireless link to the control
panel. This lock-out time can be programmed as 3 minutes or 10
minutes. Selecting the 10-minute lock-out time will prolong the
battery lifetime.
Walk testing the detector (Fig.
u
)
The DD205RF provides a walk test mode for testing the detector
operation and coverage pattern. To walk test the detector, do the
following:
1. Slightly remove the unit from the mounting plate (Fig.
u
A).
2. Replace the unit back on the mounting plate (Fig.
u
B). After
10 seconds the detector enters walk test mode for approximately
2 minutes. The generated alarms are signalled via the flashing
of the LED, visible on the front cover, and transmitted via the
wireless link to the panel.
3. Walk test the unit and verify the detection performance by

Introduction
The DD205RF/ 60-947-8A is a dual motion sensor. It has a
patented Range Controlled Radar technology. The DD205RFW8
has been designed in accordance with TS50131-2-4, EN50131-1 &
EN50131-5-3 security grade 2 and environmental class 2.
The 60-947-8A has been tested and certified as a dual motion
sensor to TS50131-2-4, EN50131-1 and EN50131-5-3 for security
grade 2, environmental class 2, by the Dutch testing and
certification body Telefication B.V.
The detector has five components (Fig.
n
):
y
Mounting plate
y
Batteries (only 2 included)
y
Base (screw included)
y
Front cover (screw included)
y
Custom insert
Positioning the detector (Fig.
q
)
The detector can be mounted in a corner or on a flat wall. Use
the following guidelines to determine the best location to install
the detector:
y
Mount the detector so the expected movement of an intruder
is across the detection pattern (Fig.
q
).
y
Mount the detector at a stable surface at a height between
1.8 m and 3.0 m.
y
Do not mount the detector within 0.5 m of metallic objects
or within 1.5 m of fluorescent lights.
y
Do not place objects in front of the detector that may
prevent a clear line of sight.
y
Avoid detectors facing each other.
y
Mount detector at least 6 m apart, and use the short-range
setting to avoid interference.
The dual technology processing of this detector is very resistant
to false alarm hazards. Nevertheless avoid potential causes of
false alarms, such as:
PIR hazards:
y
Direct sunlight on the detector
y
Heat sources within a field of view
y
Strong air draughts on the detector
y
Large animals in the field of view
Microwave hazards:
y
Mounting surface susceptible to vibrations
y
Metal surfaces reflecting microwave energy
y
Water movement through plastic pipes
y
Moving or vibrating objects like fans, heating or air-conditioning
ducts
GE Security recommends that the detector is regularly walk
tested and checked at the control panel.
Mounting instructions
1. Remove the mounting plate from the detector as shown (Fig.
o
).
2. On the mounting plate, select the mounting holes for corner
or flat-wall mounting. Make sure that the tamper screw
✼
is
correctly fitted for corner or wall mounting (Fig.
p
).
3. Using the mounting plate as a template, mark the screw hole
locations on the wall. Mount the detector at a height of 1.8
m to 3.0 m. (Fig.
q
).
4. Fasten the mounting plate to the wall (Fig.
p
).
5. Insert the batteries in the battery compartment of the base
(Fig.
r
). The detector is shipped with 2 batteries but up to
3 can be inserted.
Caution:
Do not insert any batteries in the battery
compartment of the RF transmitter board.
