GENERAL INFORMATION:
The Nos. 850,

851 and 852 Series
of Microwave
Motion
Detectors

coverage,

of false

electrical
signals,
building
radio
frequency
interference,
small random motions.
Temperature,
air turbulence
and noise have no
units.
The microwave
energy emitted
by these units
sets up a precisely
defined
pattern
;of
transmitted
and ref lected
waves in the protected
area. When an object
or a person
within
the protected
area moves through
i-h is pattern,
the motion
causes a change in
the frequency
of the reflected
waves (known as the Doppler
Effect).
The reflected
waves are continuously
monitored
by the unit,
and its electronic
circuitry
detects
the shift
in frequency
and processes
the “return
s igna I”.
‘The Nos. 850, 851 and 852 must be powered from their
own plug-in
transformers
(included)
and each contains
a rechargeable
standby
power supply
that
can provide
up to I2 hours
of operation
in the event of a power interruption:‘The
Nos. 850112,
851-12 and 852-12
require
power from a l2V. DC source that
can provide
at least
4 hrs. of standby
power.
Except as noted herein,
these
instructions
apply equally
to all models.
The Nos. 850 and 850-12 can provide
pro t ection
in areas as I arge as 50’ long and 50’
wide. The Nos. 851. and 851-12 can cover areas up to 100’ long and 30’ wide.
The Nos.
852 and 852-12 can cover areas up to 50 1 long and 20’ wide. Al I units
have continuously

THE NATURE OF MICROWAVE:
Microwaves
are high frequency
radio waves. Because of the special
nature
of microwaves,
and the high frequency
separation
from other
types of radio
transmissions,
a microwave
motion’detector
can operate
effectively
with a very Iow.IeveI
emitted
signal,
and is
not subject
to interference
from other
types of radio
transmissions.

Even
though the units

there
are conditions,
as described
below,
which may appear as an intruder
to the detector
and result
in unwanted alarms.

Penetration

Areas - through

Avoid having the unit “looking

into
areas which are not to be part of the secure area,
but are within
the
range of the unit.
Motion
anvwhere within
“sicht”
of the unit
will
result
in an alarm.
It is never a good practice
to count on penetrating
an interior
wall
in an attempt
to provide
security
in an adjoining
room.
It is very important
to understand
that although
wal Is, drapes,
partitions,
etc.
may appear to shie I d the “view”
from the detector
into certain
areas,
the microwave
energy may penetrate
these objects
and the detector
may be
sensitive
to motion
behind them.
These materials
cannot
be depended upon to limit
the covered
area.
The
range at the detector
must be adjusted
as low as possible
so that
it just
covers
the intended
area and is not sensitive
enough to motion
beyondT
This means that
in many cases the range control
will
not be set fully
clockwise.
Shadows - Large objects
in the protected
area,
particularly
metal I ic
objects
such as filing
cabinets
or machinery,
will
reflect
or block
the microwave
energy.
This can reduce or eliminate
the protection
in
an area directly
behind these objects.
In this
situation,
the coverage
will
be similar
to the pattern
of a spotlight

from the location
where the detector
is mounted:
