Setting the Jumpers
The detector provides jumpers to select the detection range and
PIR and LED operation. See Figure 6.
J2 Range - Use the jumper to cover the center pin and the pin
indicating the desired range. No jumper = 90 feet (27.4m) and
under.
90 feet (27.4m) and under
80 feet (24.4m) and under
(factory default)
70 feet (21.3m) and under
60 feet (18.3m) and under
Note
You need to set J2 as close to the intended
coverage range as possible. Overshooting the
coverage area may cause false alarms.
J3 LED -
ON = LED enabled (factory default)
OFF = LED disabled
J4 PIR -
ON = Radar only enabled
OFF = PIR and Radar enabled
(factory default)
