Description
DD400AM series 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.
Placing 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
•
Obscuring the detector field of view with large objects,
such as furniture
Anti-mask (AM) risks:
•
Moving objects less than 1 m 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
Mounting Instructions
1. Lift off the cover plate as shown (Figure 1, items 1a and
1b).
2. Open the detector (Figure 1, items 2 and 3).
3. Break out one or both cable entry holes as required
(Figure 2, item 4).
4. Mount the detector between 1.8 and 3.0 m high.
5. Select mounting holes for corner (item 5) or flat wall
(item 6) mounting (Figure 2):
- Mounting hole for swivel bracket (Figure 2, item 7).
- Mounting holes for pry-off tamper (Figure 2, item 8) must
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 (item 9) and pull it through the cable
entry hole (item 4) and strain relief (Item 10).
9. Wire the detector as shown in Figures 3 and 4.
Optional spare terminal: item 11 on Figure 2.
10. Close the detector (items 2 and 3), insert the screw
(item 13) and put the cover plate (Figure 2, item 1).
Pry-off tamper protection
The pry-off tamper switch is integrated in the PCB, which is
activated by pin (Figure 2, item 8). 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 position.
For EN 50131 Grade 3 installations, use a mounting screw in
the position shown in Figure 2, item 8.

Item
Description
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
(Figure 2, item 11).
