MX-40PI combination detector incorporates a patented "quad
zone logic" which requires detection across multiple zones
before an alarm is triggered. It guarantees false alarm protection
from 100 pound pets/animals and immunity from other smaller disturbances.
It has a built in "anti-crosstalk system," preventing
interference from matching microwave frequencies in a single area.
rejects false alarms caused by spot temperature changes such
as small to medium sized animals, air conditioners, or moving
curtains. Utilizing Quad Zone Logic, the RX-40PI couples signals
from its 78 detection zones to determine the size of its target.
LX-402 provides greater reliability against false alarms caused
by sunlight. It employs Double Conductive Shielding which resists
more than 50,000 lux of sunlight (e.g. during sunrises and sunsets).
Multi-level or Pet Alley detection patterns can be selected.
Unwanted detection areas can be easily eliminated by attaching
supplied masking strips.
VX-402 combines two PIRs, creating extra high immunity against
false alarms caused by small animals, cars and other outdoor
disturbances. It employs temperature compensation circuitry,
high RFI and Sunlight immunity and an adjustable photocell.
The VX-402R version is a wireless, multi-stabilized battery
operated outdoor detector in a weatherized back box. The VX-402REC
allows the record of a customized voice message which played
back whenever motion is detected.
