Mounting Instructions

1. Lift off the cover plate as shown (1 a and b) (Fig. !).
2. Open the detector. (2 and 3 Fig. !).
3. Break out one or both cable entry hole(s) (5), as required (Fig.
).
4. Mount the detector between 1.8 and 3.0 m high.
5. Select mounting holes for corner (5) or flat wall (6) mounting
(Fig. ).
• Mounting hole for swivel bracket (7 Fig.
• Mounting hole(s) for pry-off tamper (8 Fig.
always be used either for corner (A) or flat wall (B)
mounting.
6. Using the base as a template, mark the screw hole locations
on the wall.
7. Fasten the base to the wall.
8. Strip the cable 5 cm (9) and pull it through the cable entry
hole(s) (4) and strain relief (10) (Fig.
9. Wire the detector as shown (Figs.
• Optional spare terminal (10) (Fig.
10 Close the detector (2) and (3), insert the screw (13) and replace
the cover plate (1) (Fig.
The detector is a microwave verified PIR intrusion detector and
should be installed to optimise PIR detection. The best detection
is therefore obtained with the expected movement of an intruder
perpendicular to/or diagonal towards the coverage pattern.
Siting the Detector
The dual technology processing of this detector resists false alarm
hazards. However, avoid potential causes of instability, such as:
PIR risks:
- Direct sunlight on the detector.
- Heat sources within a field of view.
- Strong draughts onto the detector.
- Large animals in a field of view.
Anti Mask (AM) risks:
- Moving objects less then 1 meter in front of the detector.
- Small insects on the detector.
- Modern fluorescent lighting in close proximity (within 1.5 m)
Microwave risks:
- Mounting on a surface susceptible to vibrations.
- Metal surfaces that reflect microwave energy.
- Water movement through plastic pipes.
- Heating or air-conditioning fans pointed directly at the detector.
Pry-off tamper protection
The pry-off tamper switch is integrated in the PCB, which is acti-
vated by pin 8 (Fig ). To use the pry-off tamper, the mounting
hole for the pry-off tamper pin must be fixed. The pry-off tamper
can be used on a flat wall and in only one angle-mounting posi-
tion.
DD477AMC / DD497AMC only, dual loop feature (J1)

(Fig.
1. Standard Alarm Loop
Tamper output is isolated from the alarm relay output. The end-of-
line resistor in the tamper circuit is short-circuited.
Terminal 3 and 4 of the alarm relay output must be used when
connecting to the control panel.

).
Terminal 5 cannot be used as a spare terminal. Instead, use an
optional spare terminal located in the base of the detector. (11 Fig.
).
2. End-of-line Loop
Tamper output is isolated from the alarm relay output.
The impedance of the tamper loop is now 4K7.
Terminal 4 and 5 of the alarm output must be used when connect-
ing to the control panel. Impedance of alarm relay loop is 4K7.
3. Dual Loop
With a Dual Loop, the tamper and the alarm loops can be moni-
tored over two wires. In Figure
how to connect the detector to the control panel and the positions
of the Jumper J1 in the different detectors (Dual Loop, single
device and multi devices).
In normal situation (no alarm) the Dual Loop impedance is 4K7.
When a detector alarm occurs, the alarm relay contact will open
and the impedance of the Dual Loop increases to 9K4, indicating
an alarm. When the detector housing is opened, the tamper cir-
cuit will be open and the Dual Loop is interrupted, indicating a
tamper alarm.
Range adjustment (Fig.
Adjust the PIR and microwave ranges to be adjusted independ-
ently by setting J2 and J3.
Always select the appropriate range setting for the dimensions of
the area protected. Verify coverage pattern and adjust, if required.
Alarm memory (Fig.
Note: First set the appropriate active Control Voltage ("CV")
using DIP switch 6.
Connect "CV" to terminal 10 when the system is armed. When the
system is disarmed, disconnect the "CV". If an alarm occurs dur-
ing the armed period, a flashing LED will indicate which the
detector(s) caused the alarm. Re-applying the "CV" (re-arming
the system) will reset the LED indication and memory.
Remote enable/disable of walk test LED (Fig.
To walk test the detector, disconnect the "CV" to terminal 10 (latch)
and connect it to terminal 11. The detector's LED will now light up
and then go out again as the alarm relay opens and closes, mak-
ing the walk test possible.
Note 1: Only enabling the walk test will not clear alarm memory.
After disarming the system following an alarm, switch the walk
test "ON". When you switch walk test to "OFF", the indication of
memorised alarms will re-appear. Only when "CV" is re-applied
to terminal 10 (i.e. the system is re-armed) will the memory be
cleared and the LEDs turned off.
Note 2: To enable the walk test LED without a remote "CV"
input, set DIP switch 5 to the "ON" position. After the walk test,
set DIP switch 5 to the "OFF" position.
Remark: See microwave disable warning.
Note 3: Aritech recommends that the detector is regularly walk
tested and the communication with the control panel is checked.
MICROWAVE DISABLE
The DD400AMC Series has the additional feature that
whenever the system is disarmed with the walk test off,
the microwave transmitter will be switched off. The
detector will then operate as a PIR only. With no "CV"
and Switch 5 to the "OFF" position, the detector operates
also as a PIR only.
DIP switch settings (Fig.
1: When to indicate "Trouble output":
" ON " signals Trouble only when the system is disarmed (Day).
" OFF " always signal Trouble.
