Position Projection Alarm; Distance/Resistance/Interference - La Crosse Technology 616-146V3 Faqs

Position Projection Alarm

 The projection alarm has a wide base to sit on a desk or table.
 Place within range
 The maximum transmitting range in open air is 330 feet (100 meters).
 Obstacles such as walls, windows, stucco, concrete and large metal objects can
reduce the range.
 Choose a location 6 feet or more from electronics such as cordless phones, wireless
gaming systems, televisions, microwaves, routers, baby monitors, etc., which can
prevent signal reception.
 Be aware of electrical wires and plumbing within a wall. This will interfere with RF (radio
frequency) signal reception.

Distance/Resistance/Interference

Distance:
 The maximum transmitting range in open air is over 330 feet (100 meters) between the
outdoor sensor and the projection alarm. This range is in open air with ideal conditions.
 Consider what is in the signal path between the projection alarm and the outdoor
sensor.
 Avoid placing electronic in the signal path between the projection alarm and the
outdoor sensor.
Resistance:
 Obstacles such as walls, windows, stucco, concrete and large metal objects can
reduce the range.
 When considering the distance between the outdoor sensor and the projection alarm
(330 feet open air), cut that distance in half for each wall, window, tree, bush or other
obstruction in the signal path.
 Closer is better.
 Windows reflect the RF (radio frequency) signal.
 Metal absorbs the signal and reduces the range.
 Stucco has a metal mesh that absorbs the signal.
 Do not mount the outdoor sensor on a metal fence. This significantly reduces the
effective range.
Interference:
 Consider items in the signal path between the outdoor sensor and the projection
alarm.
 Sometimes a simple relocation of the outdoor sensor or the projection alarm will
correct the interference.
 Windows can reflect the radio signal.
 Metal will absorb the RF (radio frequency) signal.
 Stucco has a metal mesh that absorbs signal.
 Avoid transmitting antennas: (ham radios, emergency dispatch centers, airports, military
bases, etc.)
 Electrical wires (utilities, cable, etc.)
