  • Q: How efficient is the AX-TFR’ s energy consumption compared to conventional wired model?

    Answer: Compared to OPTEX wired photobeams detector, AX-100/200TF, the level of energy consumption is reduced down to 1/60.

  • Q: How did you achieve low energy consumption?

    Answer: Not only implementing OPTEX low energy design, but also, AX-100/200TFR adopted high quality aspherical lenses to improve accuracy of beam focus, hence photobeams are more sharply defined and minimized usage of excessive power

  • Q: Is AX-TFR compromised in performance because it’s low-energy consuming?

    Answer: Although the power consumption is lower, its performance is more than before; retaining same beam blocking ratio tolerance with new features added. AX-TFRs withstand 99% attenuated photobeams without malfunctioning.

  • Q: What is the power range (V) required to run AX-TFR?

    Answer: AX-TFRs are designed to run with current between 2.5 VDC~4.3 VDC

  • Q: Why do I have to use SAFT ‘s LSH20 (3.6V) instead of ordinary CR123A (3.0V DC)?

    Answer: Ordinary CR123A (3.0 VDC) does not have enough capacity for running an AX-TFR for a longtime. To run an AX-TFR, thirty-two CR123A cells are necessary whereas, LSH20 guarantees 3 years of operation just with four cells. LSH20, despite its uniqueness, it is widely available and its reliable performance is often used in various military forces worldwide

  • Q: Can AX-TFRs operate with one battery for each TX (transmitter) and RX (receiver)?

    Answer: Yes, It is possible that AX-TFRs operate with one LSH20 for each TX and RX. Please also be aware that using one LSH20 will reduce the expected operation period and make AX-TFRs more vulnerable to shocks and vibrations.

  • Q: How long do LSH20 batteries last?

    Answer:Under ordinary conditions LSH20 batteries last at least 3 years

  • Q: What happens if I accidentally insert batteries upside down?

    Answer: Battery box (Back box) will not turn on electricity with LSH20 batteries upside down. AX-TFRs will neither be operating nor be affected.

  • Q: At what power voltage, Low battery signal is turned on?

    Answer:Low Battery Indicator and Output will be turned on at 3.0VDC

  • Q: How can I be aware of Low battery status?

    Answer: There are two ways to check Low battery status.(1) LED indicator for Low battery status (2) Using Wireless transmitter for receiving Low battery signal.

  • Q: Can I combine AX-TFRs with wired models?

    Answer: No, please do not install AX-TFRs with any other photoelectric detector. It may cause failure to detect intrusions. If the receiver (RX) of AX-TFRs receives any beam from another wired photoelectric detectors, it becomes a factor of false alarm. In case, using AX-TFRs with OPTEX’s wired photoelectric detectors in the same site, please make sure that any beam does not come in sight of AX-TFRs.

  • Q: How long can AX-TFRs constitute a linear protection?

    Answer: AX-100TFRs can protect long distance without limitation. Please choose channel settings as suggested in a diagram below. It is important to set apart adjacent beam channels from next to each other to secure reliability

  • Q: Can I arrange AX-TFRs in a stack?

    Answer:Yes, Double stacked protection is possible

  • Q: Can I mount AX-TFRs on walls, poles or in towers?

    Answer: Yes, you can. It is also possible to mount two AX-TFRs on a same pole, back to back. When you mounting an AX-TFR in a beam tower, an optional unit “MP-4” (indicated in a picture below) is required. MP-4 includes tamper bushings for LED termination.

  • Q: What features do back boxes have?

    Answer: AX-TFRs’ backboxes feature three installer friendly specifications.
    (1) Spacious & Universal design A Backbox can accommodate two wireless transmitters. Battery holder is designed to ignore batteries installed upside down. Double-sided tapes are also included in a package to hold transmitters in the box.
    (2) Pre-wired color cables for easier installation. Wiring to wireless transmitters is made as easy as possible. Matching patterns are indicated on a label placed on a side of the box.
    (3) Tamper alarm to acknowledge both backbox and front cover removal. Tamper alarm works in three ways. Either removal of the front cover, back box or mounting plate can trigger tamper output. The latter two tampers share the same output connection placed in the backbox.

  • Q: What is an “IP rate”?

    Answer: International Protection (IP) rate is the standard defined by IEC60529. AX-TFRs’ rating is IP55. The first numeral indicates degrees of protection against dusts. The second numeral indicates degrees of protection against water. Please refer to the International Electrotechnical Commission website for detailed explanations

  • Q: Can I use the “HU-2” (an optional heating unit) for AX-TFRs?

    Answer: No, because the HU-2 works with 24VDC, AX-TFRs’ LSH20 (3.6 VDC) can not support the heating module. Not to mention the fact that AX-TFRs do not have holes to put through wires, outside power supply cannot be accommodated either. When using AX-TFRs in a tower, usage of the HU-2 is an option; however HU-2 will not produce enough heat to resist frost and condensation inside the tower.

  • Q: What outputs are there?

    Answer: There are four kinds of outputs, alarm(Form C), tamper (Form C), low battery and D.Q. Each output is available with choice of N.C. or N.O.

  • Q: What are initial settings for switches?

    Answer:Settings are as follows

  • Q: What is an “intermittent output function”?

    Answer: Intermittent output function enforces outputs to reset while photobeams continues to be interrupted. This function is effective if your wireless transmitters do not have supervised features to monitor relay status. For an example, with such transmitters, security system can be armed while beams are interrupted by an accident. Intermittent output function repeats alarms with intervals to let the system be aware of interrupted status.

  • Q: What is the “battery saving timer”?

    Answer: The battery saving timer enforces 2min intervals between alarm outputs. If the site of security involves a lot of traffic or in/out of people over a detection zone, wireless transmitters may wear out batteries quickly. The battery saving timer cancels alarms for two minutes after the initial output, preserving powers of wireless transmitters.

  • Q: Do lightning damage AX-TFRs?

    Answer: No, because AX-TFRs do not require external wirings, neither electrical surge nor noise will be induced to affect operations of AX-TFRs.

  • Q: How durable is AX-TFR against vandalism?

    Answer: AX-TFRs are very durable. OPTEX photobeams detectors are equipped with high-grade polycarbonate shells to withstand an attack of hummer. AX-TFRs also features triple tamper detection mechanism that monitors not only the wall attachment, but also front cover removals.
