Frequently Asked Questions - HX-80NAM OPTEX

What is the recommended mounting height for the HX-80NAM?

The recommended mounting height is between 2.5 m and 3.0 m (8'2" to 9'10"). The detector should be installed parallel to the ground.

How do I adjust the detection distance?

Use the upper and lower flaps to reduce the long range detection area, and the plates to deactivate the short range detection area. Refer to the manual sections 2-2 and 2-3 for flap and plate position combinations.

What does the anti-masking feature do?

The digital anti-masking feature (available on HX-80NAM) detects if the detector is covered or blocked. It uses an infrared LED and a dedicated sensitivity selector. When masking is detected, the LED blinks 3 times and the trouble output is activated.

How do I perform a walk test?

Set DIP switch 1 (LED ON/OFF) to ON. Walk into the detection area at a distance greater than 1.0 m. The red LED should light for 2 seconds when detected. After testing, you can set the switch to OFF to disable the LED.

What is the difference between HX-80N and HX-80NAM?

The HX-80NAM includes anti-masking functionality (digital anti-masking) and a trouble output, whereas the HX-80N does not. Both have the same detection coverage and basic features.

Can I wire a secondary detector to the HX-80NAM?

Yes, connect a secondary unit (e.g., another PIR or A/R detector) with a voltage-free N.C. output to the AUX INPUT terminal. Use DIP switch 3 to select AND or OR logic for alarm activation.

What is the maximum wire length for power?

For 12 V DC with AWG22 wire, the maximum length is 140 m (460 ft) for HX-80NAM. For AWG18, it is 360 m (1,180 ft). Use the table in section 3-4 for details.

How do I install the detector without the bracket?

Only if the mounting height is less than 3 m, horizontal adjustment is not needed, and the ground is level. Open the wiring knockout, pull wires through, fasten the base directly to the wall, then install the main unit.

What does the LED indicate during operation?

The red LED blinks for 60 seconds during warm-up, lights for 2 seconds on alarm, and for HX-80NAM, blinks 2 times during anti-masking booting and 3 times on masking detection (with 5s/3s off intervals).

What are the available sensitivity settings?

The PIR sensitivity selector offers HIGH, MIDDLE (default), and LOW settings. The anti-masking sensitivity has HIGH, STD (default), and OFF positions.

PIR long range detection area reduction

The detection distance in the following table can be limited by combining the positions of the flap.

Use the following table to determine the positions of the upper and lower flaps that set the required max. detection distance.

NOTES:

1. The distance may vary due to environmental conditions.
2. Always walk test the detector to confirm the detection distance.

LowerUpper	Factorydefault	b	d
Factorydefault	24.0 m(80')	N.A.	N.A.
a	118.0 m(60')	213.0 m(42'8")	N.A.
c	N.A.	310.0 m(32'10")	46.5 m(22')

NOTE: Use only the following combinations for the flap settings.

2-3 HOW TO DEACTIVATE THE SHORT RANGE DETECTION AREA

To adjust the SHORT range of detection, set the upper and lower plates as follows:

1 Remove the plate.

3 INSTALLATION

Use the bracket for normal installation. The unit may be installed directly on the wall, without the bracket, only if the following three conditions are met;

• The mounting height is less than 3m (9'10").
• Horizontal adjustment is not necessary.
• The ground must be level.

3-1 INSTALLING WITH BRACKET

Using the bracket makes it possible to adjust the unit horizontally by ± 90^ . In cases where the ground is uneven and/or not parallel with the base of the unit, it is possible to adjust the unit vertically by ± 20^ .

Caution>>

Do not change the detection length with bracket.

Use the flaps and plates to adjust the detection length.

1 Remove the Up-Down lock screw.

3-2 ADJUSTING THE VERTICAL ANGLE

For best performance, install detector parallel to the ground.

Decide the detection length. To change the detection length, adjust the flap and plate positions. Refer to the 2-2, 2-3 for the details.

3 Install the other portion of the magnet switch to the back of the main unit or the bracket. Pull the wiring through the knockouts.

4 Install bracket and the main unit to the walls surface.

5 Connect the magnet switch wiring to the tamper terminal of the main unit.

4 WALK TEST

1 Set the DIP switch 1 (LED ON/OFF) to "ON".

Note>>

The switch is set "ON" by factory default.

2 Check that the detector detects an object in the intended detection area. The installation has been successful if the LED lights for two seconds after a person walks into the detection area.

Note>>

For the walk test, move more than 1.0 m (3'3") away from the detector.

3 If the LED indication is not required at all times, set the DIP switch 1 (LED ON/OFF) to "OFF".

By connecting a secondary unit (another warning sensor), you can extend the detection area and correct false alarms. The secondary unit must have a voltage free N.C. output such as another PIR detector or AIR detector.

Notes>>

• The alarm is only activates if both the main unit and the secondary unit are activated within 60 sec.
• In OR mode, a secondary detector must be fitted. If not fitted, the unit will generate an alarm continuously.

POSITION FUNCTION
AND (Factory default)	When both the main unit and the secondary detect someone, the alarm is activated. Choose this setting when a secondary unit is not connected.
OR	When either the main unit or the secondary detects someone, the alarm is activated.

-PIR AND/OR DIP switch

Note>>

"OR" mode is appropriate for the sites that require more detectability rather than false alarm tolerance such as lighting control and camera activation.

POSITION FUNCTION
AND(Factory default)	An alarm is output when both PIR1 and PIR2 detect an object.
OR	An alarm is output when either PIR1 or PIR2 detects an object.Selecting “OR” mode makes detection range longer than “AND” mode.Walk test to readjust the detection range is required when “OR” is selected.Actual adjustment should be conducted by adjusting the bracket angle.OR mode only
