Setting the detector
See Figure 14 for jumpers and DIP switch location.
Jumpers
Jumpers set onboard EOL mode and value. The circuit is
shown in Figure 11.
JA: Set onboard alarm EOL resistor (Ra)
1 kΩ
4.7 kΩ (factory
default)
Off: No onboard alarm EOL.
JT: Set onboard tamper EOL resistor (Rt)
1 kΩ
4.7 kΩ (factory
default)
Off: No onboard tamper EOL.
Configuring the zone
To set up the zone, apply the following guidelines.
•
Select appropriate EOL resistor values with JA and JT.
For example, setting of jumper JT determines Rt value.
•
For isolated outputs remove JT.
•
Remove jumpers JA and JT to exclude onboard EOL
values.
For a single zone with all onboard resistors set, the zone
resistance can be the following.

DIP switch SW1
SW1-1, SW1-2: Radar range
Use SW1-1 and SW1-2 to set the radar range exactly to fit the
application. The radar is of a range-gating type which means
that the range of detection is very accurate.
4 m (13 ft.)
6 m (20 ft.)
SW1-3: Polarity
On: Positive polarity. Configures the inputs (WT and D/N) as
"Active high".
Off: Negative polarity. Configures the inputs (WT and D/N) as
"Active low". Factory default.
The functionality is explained in Figure 10.

(2) Polarity low
This function also depends on the SW1-5 setting. See "SW1-5:
Remote functionality" below.
SW1-4: Reserved
Do not change.
SW1-5: Remote functionality
On: Remote on. Enables WT and day/night inputs.
Off: Remote off. Disables WT and day/night inputs (factory
default).
The following functionality depends on the Remote setting.

SW1-6: LEDs
On: LEDs are enabled. See "LEDs and outputs" on page 6 for
LED functionality.
Off: LEDs are disabled for any state.
