Frequently Asked Questions - LU 115 HF THEBEN

How to install the LU 115 HF detector?

The detector can be mounted on a door frame, on the ceiling, on a wall or placed on a table. The optimal installation height is 3 to 5 m from the ground. For wall mounting, first fix the base with screws, then snap on the main body. Make sure the sensor is properly oriented towards the area to be monitored. Refer to the figures in the manual for more details.

How to set the channels to avoid interference?

Open the battery compartment, then use a screwdriver to set the HF coding selector (house channel) and the coding selector to the desired position. Avoid combination A1 to prevent interference with other devices. Make sure the transmitter and receiver are on the same channel.

What is the detection range of the LU 115 HF?

The standard detection range is 1 m x 5 m at a height of 5 m, or 0.6 m x 3 m at 3 m. The METER button setting adjusts the detection distance from approx. 1 m to 8 m. The detection zone can be refined by orienting the detector head.

How to use the mains adapter with the detector?

Remove the battery compartment cover, plug the mains adapter (6-9 V DC) into the DC jack, then pierce the pre-perforated area of the cover to pass the wire. Replace the cover and ensure sealing by blocking the hole with silicone. Note that using the adapter compromises the original sealing.

What to do if the detector LED does not light up?

First check that the batteries are correctly inserted and sufficiently charged. If using used batteries, replace them with new alkaline batteries (AA 1.5 V x 4). Also ensure that the detector is powered (if mains adapter). If the problem persists, the detector may be defective.

How to avoid false triggering?

To avoid false detections, do not point the detector at heat sources (air conditioning, hot air outlets), highly reflective surfaces (swimming pool), or moving objects (tree branches). Ensure that people or animals cross the detection zone rather than moving towards the sensor. Also adjust the brightness setting (LUX) if necessary.

How to test the detector after installation?

Set the LUX button to the 'sun' symbol and the METER button to '+'. Power on the detector then wait about 30 seconds. Walk in the detection zone; the LED should light up for about 2 seconds and the receiver should receive the signal. If necessary, adjust the position of the detector head and repeat the test.

Can the LU 115 HF be used outdoors?

Yes, the detector is rated IP44, which protects it against water splashes. It can therefore be installed outdoors, but avoid direct exposure to heavy rain. Ensure that the seals are in good condition. Note that if you use the mains adapter, the sealing is reduced.

What is the battery life?

With new alkaline batteries and normal use (about 10 activations per day at 20 °C), the battery life is approximately 6 months. Lower temperatures or higher usage frequency reduce this life. When batteries are low, the LED dims or the transmission range decreases.

Which receivers is the LU 115 HF compatible with?

The LU 115 HF is compatible with all Theben HF products operating at 433.92 MHz, such as the REC 100 HF receiver (indoor/outdoor 10 A). It can be integrated into a network of multiple transmitters and receivers for home or professional use. Ensure that the channels are set identically.

CHANNEL SET-UP

Transmitter and receiver communicate each other by having the same channel.

Transmitter LU 101/115 HF has been preset its system channel at "I" and unit channel at "9" before exiting factory. Please make sure the channel settings of receiver and transmitter are identical and the transmitter's system channel match the preset of the receiver.

However, if the user finds transmitter LU 101/115 HF and the Receiver have the same channel setting with other wireless device near by, the user DEFINITELY needs to make change on the channel setting.

Do not adjust system channel to "A" position and unit channel to "1" position on all Theben series.

Though Theben series provide 256 combinations for channel settings, the best for the user is to use 255 combinations and exclude one combination-A1 from your channel setting, because A1 is very easy to get interference from other similar product in the market that eventually makes wireless device abnormally working.

Please follow the steps below to change the channel setting of Transmitter LU 101/115 HF.

1. Remove the battery cover with a flathead screwdriver (See Fig.1).

2. Adjust the channel to a desired position with a screwdriver (See Fig. 2).

3. Pull the battery cover back.
4. Please note direction while closing the battery cover. The convex corner of battery cover should be connected to the convex area of sensor body and the small hollow inside battery cover should be placed at the bottom.

Note:

It is normal state that the detection range is divergent in different environment. Suggest not installing LU 101/115 HF in where the end zone is the main detected target

To obtain excellent performance, please mount LU 101/115 HF horizontally on ceiling or the top of door-gate and vertically on wall, table or beside door-gate.

2. Avoid Nuisance Triggering

Transmitter LU 101/115 HF can be activated by any large animals, light reflective surfaces, heat sources or a moving object.

Following guidelines will help you avoid nuisance triggering:

Avoid the object moving directly toward the sensor that brings the less sensitivity of detection. Have the object move across the pattern zone that brings more sensitivity.

• Do not aim the sensor toward any kind of lighting sources.
• Avoid aiming the sensor toward object that moves in the wind such as bushes or lawn decoration.
• Avoid mounting the sensor nearing any sources, such as heating vent, air conditioner, dryer vent or the lighting device.
• Avoid having the sensor toward the area or the object whose surfaces are highly reflective or are subject to rapid changing in temperature, such as the pool ... etc.

C. Installation Procedure

LU 101/115 HF can operate by using alkaline battery or connecting AC power by an AC adaptor. Please refer to the following for two methods of power supply:

A) Please follow the steps below to insert new batteries:
1. Remove the battery cover with a flathead screw-driver (See Fig.1).
2. Insert 4 pieces of new AA 1.5V alkaline batteries. Please note that reverse polarity may cause damage on sensor (See Fig.11).
3. Put the battery cover back.

Fig. 12

The battery's lifetime is decided by activating frequency and environmental temperature. The more activating frequencies and the lower environmental temperature is, the sooner of power consumption. In normal circumstances, alkaline battery for transmitter LU 101/115 HF can be used for about 6 months by triggering about 10 times every day at 20^ C operating environment. When the battery is running faded, LED gets faint or the transmission range becomes shorter, please repeat step 1 ~ 3 to use new batteries instead of old ones.

B) It is workable to plug AC power in DC socket instead of batteries. Usually, it is suggested to connect AC power with AC adaptor for economic reason. And in order to make the control unit work normally, please use AC adaptor provided only by original manufacture.
1. Remove the battery cover with a flathead screw-driver (See Fig.1).
2. Plug the AC adaptor in DC socket from the back cover (See Fig.12).
3. Punch the reserved knock hole on battery cover with a long nose pliers (See Fig.13).
4. Put the battery cover back and make sure the wires go through the reserved knock hole (See Fig.14).

Fig. 14

• It is not waterproof since the reserved knock hole has been broken while using AC adaptor. In order to maintain it in waterproof, you'd better use SILICONE glue to fulfill the reserved knock hole.
• Make sure take out batteries before using AC adaptor.

C) Two methods for LU 101/115 HF installation:

1. Fix transmitter LU 101/115 HF on the installing surface with screws.

1. LUX

• LUX is adjustable from the range about 5 LUX to .
• Set LUX knob to " ", the sensor can operate in darkness only.
• Set LUX knob to “ ※ ” the sensor can operate at any light level.
• The more adjustment to close " ", the sensor can operate in more ambient light level

2. Meter

• Setting knob to "-", sensor detects the smallest "field of view".
• Setting knob to "+"sensor detects the largest "field of view" to about 8m (See Fig. 24).
• The more adjustment from " _ " to "+" will extend more distance for detecting zone from about 1m to 8m.
• Suggest setting knob to "+" when LU 101/115 HF is mounted on the ceiling or the top of doorgate.

21

B. LED Function

LED (See Fig. 25) is mainly desired as the indication for sensor activation. When environment is applicable for LUX, trigger the transmitter LU 101/115 HF, LED will turn on for about 5 seconds and then turn off.

C. Walk Test

LU 101/115 HF automatically works when power turns on. If it is necessary you can use walk test to test and adjust the detection coverage, which helps to make it work properly. Before the test, adjust LUX to " 心 ", meter to "+" then you can start walk test.

Procedures of walk test:

1. Aim the Transmitter LU 101/115 HF across the traffic pattern where you want to detect.
2. Warm up the transmitter for about 30 seconds.

3. Make sure the transmitter and the combined receiver have set with the same channel.

4. Check if LED of transmitter LU 101/115 HF works normally.

5. Have someone walk across the pattern from outside of coverage until LED turns on.
6. When Transmitter LU 101/115 HF is triggered at the first time, LED will turn on for about 2 sec. and send out the signal to receiver, then turn off. It takes about 5 seconds for the transmitter to reactivate. If transmitter keeps being triggered within the 5 seconds (after the first trigger), the time meter will recount. Transmitter will NOT activate, which means it will not send out the signal to the receiver. Transmitter needs to be at non-triggered status for at least 5 seconds after being triggered at first time, then it is able to be activated again.
7. The detection zone is adjustable by adjusting meter and sensor head.
8. Repeat step 6 to step 8 until the detection coverage zone meets your requirement.

Note: Whatever the meter knob to be adjusted at any position, the farthest of detection range can not be treated as normal detecting area.
