Setting the sensitivity, range, and LED
The unit provides three jumpers to set sensitivity (J1), range
(J2) and LED (J3). See Figure 7 below.
Sensitivity (J1)
BI = Bi-Curtain Mode (factory default). Increases false alarm
immunity in smaller areas. Requires the intruder to pass
through two curtains to trigger an alarm. Do not use for single
curtain applications or ranges under 5 feet (1.5m).
STD = Standard Sensitivity. Use for most wide-angle or
single curtain applications. Requires the intruder to pass
through only one curtain to trigger an alarm.
Range (J2)
Program J2 for range under 33 feet (10.1m, factory default
for AP450A) or to 50 feet (15.2m, factory default for AP450).
It is important to program the sensor correctly for optimum
sensitivity. Walk test the sensor regularly by walking across the
fields of view and checking that the LED lights and that the
opening relay is indicated back at the control panel.
LED (J3)
You can change the LED from enabled (factory default) on
the AP450 sensor (does not apply to the AP450A) to remote
controlled, by moving jumper J3 to the OFF/Remote position.
The LED can then be enabled remotely by applying a 0V
potential to terminal 8.

Pet alley application
To create a detection-free area close to the floor, mount the
unit 3.5 feet (1.1m) above the floor, upside down (sensor
window towards the ceiling). The cardboard undercrawl
window mask should be in place to reduce exposure to the
ceiling. As shown in Figure 8 below, pets are free to roam
below the mounting height of the unit without causing an
alarms.
