4.3 Tripod installation
1. Open the tripod so the bottom yellow plastic part is approximately 25 cm from the bottom end
of the tube (see the picture below). Secure the position by tightening the locking screw.
2. Attach the photocell to a steel plate located on the top of the tripod via magnet located on the
bottom of the photocell.
3. Screw antenna onto the top connector of the photocell (see page 8). But not tighten the nut yet!
Set the antenna to the perpendicular position first, then tighten the nut.
!!
If you tighten the nut before the antenna is set to the correct position, it could cause
damage to the antenna
!!
4. Set the height of the tripods based on your needs (We recommend placing the photocells/
reflector pairs in height of 100 - 110 cm from the ground). Make sure that the photocells and
reflectors are in the same height so the beam of the photocell falls in the middle of the reflector.
Do not place photocells on the ground as the radio signal will be low.
5. Place the reflector at a distance of 2 - 5 m from the photocell (Do not exceed the 6 m distance).
• If the photocell is switched on and the beam does not fall onto the reflector, the photocell will
produce a
continuous audio signal
. Thanks to the audio signal, it is easy to alight the
photocells and reflectors properly (no audio signal indicates a correct alignment of the photocells
and reflectors).
• Each time the photocell’s beam is broken, an
audio signal
is produced and the optical signalling
LED bulb (9) will be lit.
