C. Installation procedure
Note:
Before starting to install the sensor, please test and make sure that the
sensor and the combining receiver can work normally in the selected
zone.
The sensor can be mounted on the wall (See FIG.7), ceiling (See
FIG.8), or a table (See FIG.9). However, make sure that the “TOP” of
the sensor is upside no matter wherever is chosen to mount.
- Ceiling Mount -
Rotate the sensor head clockwise until “TOP” is to the most upside.
1. Loosen the screws of the front case with a screwdriver (See FIG.
11). The screw will not fall down they, will stay in the front case’s
screw holes.
2. While take apart the bottom case from the front case, pull front case
upward till it is separated from bottom case naturally (See FIG.12).
3. Fix the bottom case onto the wall with screws (See FIG.13).
4. Put 4PCS 1.5V type AA batteries into inner case, check carefully
the battery polarities (+ and -) are in correct directions (See FIG.14).
Reverse polarity would cause Transmitter TVTXS burned down.
5. Insert front case into already fixed bottom case (See FIG.15).
6. Fasten front case firmly with the screw (See FIG.16).
(2). Sensor head is adjustable downward to maximum angle 70° (See
FIG.2).
Avoid nuisance triggering
The detector TVTXS can be activated by any large body, light reflec-
tive surface, heat source or a moving object. Following guidelines will
help you avoid nuisance triggering.
1 - Avoid the object moving directly toward the motion detector that
should brings the less sensitivity of detection. The objects have to
move across the pattern zone in order to have more sensitivity of
detection.
2 - Do not aim the sensor toward any kind of lighting sources (See
FIG.4)
3 - Avoid aiming the sensor toward object that moves in the wind, such
as bushes or lawn decorations (See FIG.5)
4 - Avoid mounting the sensor near any heat source, such as heating
vent, air conditioner, dryer vent or lighting device (See FIG.6)
5 - Avoid place the sensor toward the area or the object whose surfaces
are highly reflective or are subject to rapid changing of temperature,
such as the pool, etc.

More sensitivity by
crossing the motion
sensor.
Less sensitivity by
directly moving toward
the motion sensor.
