Jumpers
J1: PIR sensitivity
It changes the distance-to-alarm delay (the speed of the
decision algorithm); the higher the sensitivity, the faster the
sensor will react.
See Figure 14.
There are three different PIR sensitivities.
Low sensitivity: Use where there is a risk of false
alarms. Do not use in long-range applications
(>20 m / 65.6 ft.) or single-curtain applications
(item 1).
Medium sensitivity: Most situations (factory default)
(item 2).
High sensitivity: Use for high-risk situations.
Recommended for use in corridors (item 3).
Note: For UL/cUL installations, range of 65 ft and 180 ft
requires maximum sensitivity setting (item 3).
J2: Curtain location mode (CLM)
It allows you to identify where the edges of the curtains are
precisely located. When an intruder enters a curtain, the red
and yellow LEDs flash alternatively.
See Figure 15.
J2 is also used for long-range alignment (see "Aligning the
beam and walk testing the detector" on page 8).
Off (item 1).
On (item 2). See "Aligning without the alignment tool"
on page 8.
J3: Dual loop (only available in VE735AM)
It is used to set the alarm and tamper relay. It allows you to
connect the detector to any control panel.
See Figures 16 and 17.
EOL Loop (4.7 kΩ)
Terminals 4 and 5 of the alarm output must be used
when connecting to the control panel.
Isolated Alarm and Tamper Loop (factory default)
Tamper is isolated from the alarm relay. The EOL
resistor in the tamper circuit is short-circuited.
Terminals 3 and 4 of the alarm output must be used
when connecting to the control panel.
Dual Loop
Tamper and alarm loop can be monitored over two
wires.
In a normal situation (no alarm) the dual loop
impedance is 4.7 kΩ. For a detector alarm, the alarm
relay contact opens and the impedance of the dual

loop increases to 9.4 kΩ, indicating an alarm. When
the detector housing is opened, the tamper circuit
opens and the dual loop is interrupted, indicating a
tamper alarm.
Terminals 4 and 5 are linked.
Zone inputs of the control panel are connected to
terminals 4 and 7.
Terminals 3 and 6 are not used.
PIR DIP switches
See Figure 11, item 7.
Table 1: PIR DIP switches
Function DIP switch On
1. Polarity Active high*
2. Chime Chime on
3. Chime direction Left-to-right*
4. LEDs LEDs on*
* Factory default
DIP switch 1: Polarity of control voltage (CV)
On: "Active high" provides the standard logic with "Active high"
logic to enable walk test and day/night inputs.
Off: "Active low" provides "Active low" logic to enable walk test
and day/night inputs.
DIP switch 2: Chime
See Figure 12.
The detector can distinguish the direction of the intruder during
daytime. Disable this option by setting the detector to chime
OFF. When the chime is ON, the detector will trigger an alarm
when the intruder moves right-to-left or left-to-right across the
curtains.
Note: If the day/night terminal is not used and the chime is ON,
the chime will be ON both during disarm and arm (day/night)
mode.
DIP switch 3: Chime direction
See Figure 13.
On: Alarm when an intruder walks from left-to-right.
Off: Alarm when an intruder walks from right-to-left.
Stand with your back to the detector to determine left and right
directions.
DIP switch 4: LEDs
On: Enables both LEDs on the detector at all times.
Off: Puts both LEDs under the control of walk test and
day/night input.
