EN: Installation Sheet
Description
The DD490 series detector is a microwave verified PIR and
should be installed to maximise PIR detection. The best
detection is therefore obtained with the expected movement of
an intruder perpendicular and/or diagonal to the mounting
location.
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
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
See Fig. 1.
1. Lift off the cover plate (item 1) as shown.
2. Open the detector (item 2) and remove electronic module
(item 3), taking care not to touch pyroelectric sensor
(item 4).
3. Break out one or both cable entry hole(s) (item 5) as
required.
4. Mount the detector between 1.8 to 3.0 m high.
5. Select mounting holes for corner (item 6) or flat wall
(item 7) mounting.
6. Use the base as a template for marking screw hole
locations on the wall.
7. Fasten the base to the wall.
8. Strip cable for 5 cm and pull it through the cable entry
hole(s) (item 5) and strain relief (item 9).
9. Replace the electronic module (item 3) and wire detector
as shown (Fig. 3 and 4).
10. Replace cover (item 2), insert screw (item 8) and replace
cover plate (item 1).

Walk test LED functions
See Fig. 3.
To walk test the DD495/DD496 make sure jumper J3 is in the
ON position or the LED is enabled remotely.
In the DD497/DD498 the LED must be enabled by applying a
CV signal to terminal 10.
Select the required function of the LED at jumper J1.
•
DUAL: Detector Alarm. The LED lights when the detector
is in alarm. Relay follows LED.
•
MICROWAVE: Microwave Alarm. The LED lights when the
microwave channel is in alarm. Relay is always in alarm.
•
PIR: PIR alarm. The LED lights when the signal in the PIR
channel exceeds the alarm level. Relay is always in alarm.
Use MICROWAVE and PIR when required to locate the
coverage patterns of the individual technologies.
Range adjustment
See Fig. 3.
Program the range at jumper J4.
•
20 m: Maximum range up to 20 m.
•
12 m: Medium range up to 12 m.
•
7 m: Minimum range up to 7 m.
Always select the lowest range setting possible for the
dimensions of the protected area.
1. Select PIR channel on jumper J1. Verify PIR coverage and
adjust if required.
2. Select MICROWAVE channel on jumper J1. Verify
MICROWAVE coverage and adjust if required.
3. Select DUAL processing on jumper J1 and verify unit
detection.
LED jumper and remote control of LED
(DD495/DD496)
See Fig. 3.
Move jumper J3 to position OFF/REMOTE. The LED is now
disabled. It may be enabled by moving the jumper J3 to the ON
position or remotely by applying a 0 V potential to terminal 8.
Alarm memory (DD497/DD498)
See Fig. 3 and 4.
Note: First set the Control Voltage (CV) by jumper J2.
Connect CV to terminal 9 when the system is armed. When
system is disarmed, disconnect the CV. If an alarm has
occurred during the armed period, the detector or detectors
which gave the alarm are indicated by a flashing LED. Re-
applying the CV (rearming the system) will reset LED indication
and memory.
Remote enable/disable of walk test LED
To walk test the detector, the CV to terminal 9 (latch) must be
disconnected. Connect CV to terminal 10. The detector's LED
will now light and go out again as the alarm relay opens and
closes, making possible walk testing.
