Each unit consist of a cover, a mounting plate
and the main part with the electronics:
1. Terminals
2. Signal LED (only on receiver)
3. Alarm LED (only on receiver)
4. Voltage measuring points (only on receiver)

The main part is attached to the mounting plate with 1 screw at the bottom, which is visible only when the cover is off.
3. Mounting Location
• Make sure there are no obstructions between the transmitter and the receiver (trees, bushes, clotheslines etc.).
• Avoid strong light (sun, car headlights, etc.) shining directly on transmitter or receiver. When strong light stays in
the optical axis for a long time, it does not cause malfunction but will reduce the product life.
• Do not install the units where they may be affected by dirty water or direct sea spray.
• Do not install the units on unsteady surfaces.
• The receiver has to be placed within the detection range (30m/100ft) and the spread of the beam (∅0.9m/3ft at
30m/100ft) of the transmitter.
• Install the sensors at a height of 0.8 to 1m (± 3ft), the ideal height to capture human passers-by.
• With the sensor block adjustments (#7 and #9 in the picture above), a large variety of mounting combinations are
possible. Read "6. Alignment" on p. 3 for precise guidelines.
