Frequently Asked Questions - AX-330PLUS OPTEX

What is the detection range of the OPTEX AX-330PLUS?

The detection range is 100 m (330 ft). The maximum arrival distance between units is 1000 m (3300 ft).

How do I align the transmitter and receiver?

Use the viewfinder to center the other unit, then fine-tune horizontally and vertically using the adjustment dials. Check the LED indicator and monitor jack voltage to achieve at least 3.0V for excellent alignment.

What should I do if the alarm LED stays on even when the beam is not blocked?

This indicates poor alignment or a wiring issue. Re-perform optical alignment and check the monitor jack voltage. Ensure the voltage is at least 3.0V. Also verify wire connections per the terminal and wiring section.

How can I reduce false alarms caused by birds or small animals?

Adjust the beam interruption time to a slower setting (e.g., 500 ms) to ignore fast-moving small objects. Also ensure the mounting is stable and there are no reflective objects within 1 m of the beam path.

What is the power supply requirement for the AX-330PLUS?

The power supply must be 10.5 to 28 VDC. The current consumption (transmitter + receiver) is 46 mA max during normal operation.

How do I clean the detector lenses?

Use a dry soft cloth or mild soap and water. Do not use oil or alcohol-based solvents as they can cloud or etch the cover.

Can I mount this detector outdoors?

Yes, the AX-330PLUS is suitable for outdoor use. It has an anti-frost structure and operates in temperatures from -25°C to +55°C. However, avoid installing where trees or objects may swing and block the beam.

What does the alarm output relay do?

The alarm output is a Form C relay rated at 28 VDC, 0.2 A max. It switches when the beam is interrupted, allowing connection to an alarm panel.

Are there any optional accessories for this detector?

Yes, optional accessories include the Heating Unit (HU-2) for frost prevention and the Back Cover (BC-2) for additional protection.

What should I do if the detector does not respond after power is applied?

Check that power wires are correctly connected and polarity is correct. Ensure input voltage is within 10.5-28 VDC. If still not working, test for shorts/open circuits and contact technical support.

3 Wiring distance

• When using two or more units on one wire, the maximum length is obtained by dividing the maximum wire length listed right by the number of units. (a detector = a receiver or a transmitter.)
• The power wire should not exceed that.

m (ft.)

Wire size	12 VDC	24 VDC
AWG 22(0.33 mm ^2 )	500(1 600)	2 500(8 100)
AWG 20(0.52 mm ^2 )	800(2 600)	4 000(13 000)
AWG 18(0.83 mm ^2 )	1 200(4 000)	6 000(19 500)
AWG 16(1.31 mm ^2 )	2 000(6 500)	10 000(32 500)

3 Beam interruption time adjustment

Beam interruption time adjustment is on the receiver unit. This function allows you to adjust the sensitivity of the device to fit to surroundings. A slower setting means less sensitivity.

Time adjustment (Receiver)
Typical interruption time setting	Running Jogging Walk fast (50 msec) (100 msec) (200 msec)			Walk slow (350 msec)	Slow movement (500 msec)

Caution

The speed shown above is the maximum detectable speed for each setting.Faster speed will not be detected. For cases where birds, newspapers, or suspended matters may accidentally interrupt the beam, adjust the set value to a slower speed (longer interruption time).

4 Optical alignment

The reliability of photoelectric detector depends on the level of optical alignment.

Use the following method to ensure that the maximum voltage can be obtained from the monitor jack by means of a voltmeter.

4-1 Horizontal and vertical alignment

Observe the viewfinder of the transmitter and the receiver. Adjust the lens from horizontal and vertical directions, so that the other unit is in the center of the viewfinder.

2. Look into the viewfinder, and turn the horizontal alignment dial for fine adjustment.

2 Vertical alignment

1. Look into the viewfinder, and turn the dial for fine adjustment by screwdriver or manually.

2. Right; upward / left; downward

4-2 Check by alarm LED

Remember to obtain the maximum voltage from the monitor jack by using a voltmeter so as to obtain the most stable beam (refer to Step 4-3).

Alarm LED indicator status

LED ON: The beam energy emitted by the transmitter has not yet reached to the receiver. LED OFF: The beam energy emitted by the transmitter has reached to the receiver. *Before moving to the next step, confirm that LED indicator is OFF.

4-3 Carry out check from monitor jack

After adjustment by observing the LED indicator, use a voltmeter to check the voltage on the monitor jack to obtain the most stable beam.

Insert the probe of the voltmeter into the monitor jack in front end of the receiver.

The beam alignment level can be obtained by comparing the measured voltage values with the parameter values in the following table. To obtain an excellent alignment level, the measured voltage value must be greater than 3.0V.

Alignment level	Poor	Realign	Fair	Good	Excellent
Monitor jack output	0 V ▶ 1.5 V ▶ 2.5 V ▶ 2.7 V ▶ 3.0 V ▶
Optical alignment for indoor useThe maximum voltage obtained from the monitor jack should be at least 2.5 V or more.

4-4 Walk test

1. Check that the alarm indicating lamp is OFF.
2. If the beam is not blocked and the indicating lamp is still ON, re-perform optical adjustment and check the wire connection (refer to Section 2-3).
3. After adjustment and normal operation of the device, perform walk test at least 3 locations as in the following :
   • In front of the transmitter
   • In front of the receiver
   ● Midpoint between the receiver and the transmitter

Important

The majority of false activations can be attributed to poor beam alignment.

When aligning the outdoor beams, accept the value of no less than the "EXCELLENT" value for the most stable and trouble free system.

Refer to the Installation Instructions for acceptable monitor jack voltage values.

Note;

This device is designed to detect moving objects and trigger alarms to the control panel.

It is only a part of the entire alarm system, and we do not bear the losses or consequences caused by invasions.
