INSTALLATION INSTRUCTIONS

· Optex presents a new concept, , which protects a building’s exterior by detecting intruders before an entry is attempted. In addition to signaling an
alarmsystem, can create an audible local alarm to deter intruders before a break-in occurs.

· BX-80N is a passive infrared detector which detects the infrared heat energy that is emitted by humans and is designed with this concept.

- Individual N.O.& N.C.outputs.

- BX-80N’s built-in buzzer can sound an alarm while an alarm is occurring. This buzzer can also be used to
annunciate detection during area check mode ( See section 8-3 DIP Switch Setup).

- Since both upper and lower fingers have to be blocked at the same time to be activated, the
detection range of the BX-80N can be limited to avoid detecting unwanted object.

- Upper and lower detection fingers must be blocked simultaneously to activate the detector. BX-80N does
not detect objects which do not block the upper fingers.

- IP rating : IP 55

- This patent listed shielding greatly reduces the chance of false alarms due to car headlights, sunlight and
other ambient light sources.

Before installation, make sure to read this instruction manual carefully for safe and effective product operation.

7. AREA SETUP

7-1. Area Angle Adjustment

Move the lens to select the angle (0 or 3 degree) of the detection areas
as shown above and confirm that the lens is unhooked from the groove
on the lens holder.

7-2. Detection Length Adjustment

The upper detection finger stays parallel to the ground at all times. The
lower detection finger moves as shown in this section depending on the
position. So, the length of detection is limited by the angle of lower finger,
since both upper & lower fingers have to be blocked at the same time to
activate detector.

Both upper and lower
fingers are blocked!

Only upper finger is
blocked!

Only lower finger is
blocked!

Adjust the detection length by sliding the lower lens as shown.
(The lower areas are adjustable on right and left sides independently.)
Do not press hard.

The lower detection finger can be adjusted to control the detection length as

shown below:

· Installation height must be between 2.7 ~ 4ft.(0.8m ~ 1.2m).

· The maximum detection length may vary as above due to
environmental thermal conditions.

· Detection range depends on installation height.

Detection

Remove the lens holder from the front cover as described in section 7-1.

The lower lens slides to adjust the detection length. Select the appropriate position

from the guide on the lens holder (A,B,C or D).

Make sure to conduct walk tests after changing the position.

The LED lights and the area check mode (See section 8-3) can be used to identify

detection areas. If the detection areas are not appropriate, re-adjust the detection

length by sliding the lens to a different position on the lens holder.

If there are obstacles blocking the detection fingers, the angle of the fingers can be adjustable horizontally with the lens setting 0 or 3 degrees to keep a distance from the obstacles.
Because of the detection technology (pulse count setting = 2) of BX-80N, both upper and lower detection fingers should be triggered for alarm activation. Therefore, make
sure that the both detection fingers should be set at the same angle from the wall so that they are triggered at the same time. In this case, sensitivity [ HI ] is recommended
when greater sensitivity is required around the rated area (near 12m).

· Avoid adjusting the horizontal angles of only the upper or lower detection finger separately. BX-80N requires both upper and lower fingers to be
blocked to make an alarm. So, if you adjust the horizontal angle of the detection areas, do it for both of them together. When the both angles are
adjusted horizontally, sensitivity adjustment should be set to [ HI ] . (See section 8-1 Sensitivity Adjustment)

If you select the 3 degree angle, the detection area will be 1.97ft.(0.6m)
away from the wall at 40ft.(12m).

[ Detection length setting chart (single side) ]

After selecting the detection area adjust­ment, replace the lens holder in the front
cover by aligning the three tabs (A, B and
C) on each side of the lens holder with the
three grooves (A’ , B’ and C’ ) on the front
cover.
