Selecting The Coverage Patterns; Window Mask - GE DD450 Serie Manual De Instrucciones

• 5 m = minimum range up to 5 m
DD470 series
• 16 m = maximum range up to 16 m
• 10 m = medium range up to 10 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
(DD455, DD456, DD475, and DD476 only)
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 (DD457, DD458, DD477, and
DD478)
See Figure 2.
Note: First set the control voltage ("CV") with 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 the 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 walk testing possible.
Notes
• Enabling the walk test will not clear alarm memory. After
disarming the system after an alarm, you may switch to
walk test. When you switch back out of walk test, the
indication of memorized alarms reappears. Only when
"CV" is reapplied to terminal 9 (i.e. system is rearmed) will
LEDs and memory be cleared.
• To enable the walk test LED without a remote "CV" input,
connect a link between terminal 2 and 10, J2 = "+".
Microwave disable
The DD457, DD458, DD477, and DD478 detectors have the
additional feature that whenever the system is disarmed with
the walk test off, the microwave transmitter is switched off. The
detector then operates as a PIR only. In all other configurations
the unit operates in the dual technology mode.

Selecting the coverage patterns

Mask the appropriate mirror curtains with the adhesive labels
provided and reassemble the sensor module.
For example: See Figures 7 and 8 for mirror curtain coverage
pattern corresponding to curtain 3, 6A, and 7B (DD450 series)
and curtain 2, 7A, and 9B (DD470 series) masked.
Caution: Removing labels can damage the mirror surface.

Window mask

In the presence of objects close to (within 1.5 m) and directly
under the detector, fit the mask to the inside of the window as
shown in Figure 9.
This disables the part of the curtains looking at the object,
whose closeness might otherwise destabilize the detector.
DD470 series
The coverage pattern can be changed to fit specific
requirements using the mirror masks as shown in Figure 10.
Mask off unused curtains which might otherwise be looking at
walls or windows very close to the detector.
