FAQ on OPTEX Products

GENERAL (4)

Answer: No, PIR sensors detect the temperature difference between the detection goal and the bottom inside the detector’s field of view both when the difference is positive or negative. During the day the flat temperature can reach 50-60 degrees Celsius, whereas the human body maintains it at 30 degrees Celsius. This 20-degree difference is more than enough to detect intruder’s presence.

Category: 

Answer: The detector might not be installed at the proper height or angle. See installation manual to know the installation instructions.

Category: 

Answer: If you give us more detailed information on your application (plans, photos, diagrams) and the desired protection level, our team can advise you on the installation layout.

Category: 

Answer: No, our detectors work as peripherals which detect someone’s presence inside the detection zone. A control panel is needed to connect and control our detectors in order to create a security system against intruders.

Answer: Yes, the bracket which comes with the HX unit is installed in a single electrical box.

Category: 

Answer: It can be powered independently by using CR123A or CR2. Moreover, you can share the wireless transmitter’s batteries.

Category: 

Answer: No, the HX-40RAM does not include a communication transmitter although it is compatible with most of the brands. The detector has a rear compartment to hold inside a wireless transmitter.

Category: 

Answer: The bracket enables a horizontal adjustment of 180 degrees or a vertical one of +/- 20 degrees.

Category: 

Answer: When it is set in AND position, the HX only generates an alarm when both the superior and the inferior detection zones are cut off. When it is in OR position, the HX generates an alarm when either the superior or the inferior detection zone is cut off.

Category: 

Answer: The installation height is from 2.5 m to 3 m.

Category: 

Answer: Never change the detection distance by adjusting the bracket. Always use the masking tape in order to adjust the detection distance.

Category: 

Answer: The HX uses AND detection which means that both superior and inferior detection zone must activate in order to trigger the alarm. Moreover, the original configuration sums width between each detection zone to prevent false alarms caused by pets or small animals.

Answer: The AX-TFR are highly resistant towards vandalism. The AX-TFR have high-quality polycarbonate housings which resist heavy impacts. They also have a triple tamper protection mechanism which monitors both wall contact and front cover removal.

Category: 

Answer: No, as the AX-TFR do not need external wiring, they are not susceptible to electric surges nor to noise.

Category: 

Answer: The battery saving timer imposes 2-minute intervals between each alarm output. If there is a lot of traffic in the controlled zone or if there are persons entering and leaving, the wireless transmitters can quickly drain the batteries. The battery saving timer cancels the alarms during the two minutes after the first alarm, which enables it to save wireless transmitters’ energy.

Category: 

Answer: The intermittent output function forces each output’s restart when the photoelectric beams are cut off constantly. It is useful in case wireless transmitters do not enable supervisory operations to monitor the actual condition. As an example, the security system can arm itself with these transmitters when the beams are cut off by accident. The intermittent output function repeats the alarms at intervals in order to indicate the interrupted status to the system.

Category: 

Answer: Settings are as follows:

  Setting Position
Interruption time 50 msec Up
Battery saving OFF Up
Intermittent Output OFF Up
N.O./N.C. selection for Low Battery and D.Q. outputs N.C. Up
Category: 

Answer: There are four types of outputs: Alarm (Form C), Tamper (Form C), Low Battery and D.Q. (Environmental Disqualification). You can choose N.C. or N.O. for each of them.

Category: 

Answer: No, because the HU-2 works with 24 V CC; the battery LSH20 (3,6 V CC) from AX-TFR does not tolerate the heating module. Moreover, the AX-TFR do not have mounting holes where to introduce the cables which means they cannot be powered externally. When using AX-TFR equipment in a tower, it is possible to use one HU-2. This unit, however, does not produce enough heat to resist frost and condensation which appear inside the tower.

Category: 

Answer: The International Protection Rating (IP for English initials) is a norm defined by IEC60529. AX-TFR’s rating is IP55. The first number indicates the protection level against dust. The second one indicates the protection level against water. The International Electrotechnical Commission’s website offers more detailed information.

Answer: AX-TFR’s back boxes offer three useful specifications for the installer:

(1)   Back box A, spacious and with universal design can hold two wireless transmitters. The battery bracket is designed to ignore the ones placed upside down. There are also, on both sides, adhesive tapes to hold transmitters.

(2)   Coloured cables already placed to make the installation easier. Wireless transmitters’ wiring is facilitated to the maximum level. A label on the side of the box shows the coinciding patterns.

(3)   Tamper alarm to recognise if back box or front cover has been removed. This alarm works in three ways: front cover’s removal, back box or a mounting plate can activate it. The last two share, in the back box, the same output connection.

Category: 

Answer: Yes, you can do it. It is also possible to install two AX-TFRs on the same pole, one with the back side towards the other. In order to install an AX-TFR on a tower, you need “MP-4” optional unit (which can be seen on the photo below). The MP-4 contains tamper bushings for LED indicators’ termination.

Category: 

Answer: Yes, it is possible. Use different channels to prevent inferences.

Category: 

Answer: No, AX-TFR should never be installed with any other photoelectric detector. There can be failures in the intrusion detection. If AX-TFR’s receiver (RX) receives any of the beams from other wired photoelectric detectors, it can provoke a false alarm. If you, in any case use AX-TFR equipment with OPTEX photoelectric wired sensors in the same place, make sure that none of the beams remains visible to AX-TFR.

Category: 

Answer: There are two ways to notify that the battery is low: (1) by using the LED Low Battery indicator; (2) by using a wireless transmitter in order to receive Low Battery sound.  

Category: 

Answer: Low Battery indicator activates at 3,0 V CC.

Category: 

Answer: The battery box (back box) will not activate electricity if LSH20 batteries will be upside down. AX-TFR do not work, nor are they affected by this.

Category: 

Answer: LSH20 batteries last at least 3 years in normal conditions.  

Category: 

Answer: Yes, the AX-TFR can operate with just one LSH20 battery per each transmitter and receiver. Nevertheless, using only one battery reduces operation time and it leaves AX-TFR more vulnerable to impacts and vibrations.

Category: 

Answer: CR123A’s capacity (3,0 V CC) is generally not enough for AX-TFR to work during a lot of time. In comparison, LSH20 models work three years with only four batteries.

Category: 

Answer: The AX-TFR are designed to operate on currents from 2.5 to 4.3 V CC.

Category: 

Answer: Even though the energy consumption is lower, its performance is superior: it maintains the same tolerance in relation to beam blocking, but with new features. AX-TFRs withstand 99% attenuated photoelectric beams without failure.  

Category: 

Answer: We do not only implement OPTEX low consumption design, but the AX-100/200TFR models have high quality aspheric lenses in order to improve pointing accuracy, which is why photoelectric beams are defined more precisely and they minimize the use of energy.

Category: 

Answer: When compared to AX-100/200TF wired photoelectric detector, the energy consumption level reduces to 1/60.

Category: 

Answer: It is a system which sends a disturbance signal when the beam intensity, due to thick fog, rain or snow is lower than acceptable. The disturbance signal is maintained meanwhile beam intensity is lower than the acceptable level.

Answer: The batteries should last from 3 to 5 years depending on the model.

Answer: AX-TFR series does not include communication transmitters even though it is compatible with most of the wireless brands. The sensor has a rear compartment to host communication transmitters.

Answer: 4 lithium D-size 3,6 V batteries are needed (13A/hrs).

Answer: Yes, there are heaters available. Note: the heater power supply is 24 V CC/CA, 430 mA, which is why it is always advisable they have their own power supply.

Answer: After aligning beams with a viewfinder, confirm the beam alignment level using voltmeter. The lecture should be from 2.3 to 5 volts depending on the model.

Answer: Only the ones from TF series can be stackable. These equipments have a 4-channel beam frequency selector switch.

Answer: Yes, the relay changes its position. This can be avoided by installing a backup battery.

Answer: You only need a voltmeter to measure the alignment voltage.

Answer: This function allows adjusting units’ sensibility depending on the intrusion speed. As an example, in order to protect a wall or a fence, a larger interruption period will let us catch an intruder while it will also limit the shots provoked by birds or cats.

Answer: Increase the beam interruption time.

Answer: At any distance, providing you can place the cover. They should not be placed too close; the key is to exclude that the intruder jumps over or that it crawls under the beams.

Answer: The minimum advised height is .08m, due to the reflection occurrence possibility. Furthermore, it is not advisable to install them very low considering that an intruder can jump them without being detected. 

Answer: All of them excluding TN series.

Answer: An AVF-1 (Area Viewfinder) and an OPM-WT (Walk Tester) are needed. The cover plate is in the box and it is specific for each unit.

Category: 

Answer: SIP-HU (heating unit) and MINI or MIDI hood for SIP (sun and snow protection).

Category: 

Answer: Detection logic selector controls AND/OR logic. AND logic is when both distant and nearby zone must be detected in order to activate the alarm. OR logic is when an alarm is activated by either a nearby or a distant detection.

Category: 

Answer: In order to align the Redwall SIP units correctly, you need a Walk Tester (OPM-WT) and an Area Viewfinder (AVF-1).

Category: 

Answer: Yes. To see what must be masked inside the detection area AVF-1 Area Viewfinder (accessory) is needed. There are, inside the sensor, both masking plates and tapes to eliminate unwanted zones.

Category: 

Answer: SIP3020/4010/404 models need 11-16 V CC or 22-26 V CA. 12 V CC is used only with SIP3020 CAM DN models.

Category: 

Answer: Yes, SIP-HU can be used in the following models: SIP-3020, SIP-3020/5, SIP-4010, SIP-4010/5, SIP-404, SIP-404/5, SIP-5030 y SIP-100.

Note: by using "SIP-HU" heater, SIP unit power supply should be from 22-26 V CA.

Category: 

Answer: All of the Redwall units have a one-year warranty.

Category: 

Answer: Neither detections nor false alarms can be detected. The sensor loses its reliability and its range decreases. There is a possibility it does not detect most of the intrusions.

Category: 

Answer: From 2.3 to 4 m high.

Category: 

Answer: SIP stands for PIR (passive infrared sensor) for Intelligent Tuning.
