At the recommended height of 2.1m (7ft) to 2.7m
(9ft) ± 10%, MG-PMD85 provides full coverage
from 1.5m (5ft) to 11m (35ft) as shown in Fig ure 5
on page 32. The MG-PMD85 includes a
weatherproof casing so it can be installed outside.
Avoid placing the detector within proximity of the
following sources of interference such as direct
sunlight, reflective surfaces and moving cars.
Do not touch the sensor surface as this
could result in a detector malfunction. If
necessary, clean the sensor surface using a
soft cloth with pure alcohol.
Avoid bending, cutting or altering the
antenna or mounting the detector near or on
metal, such as aluminum siding, as this may
affect signal transmission.
After selecting the detector's location, drill or punch
out holes for the screws (Figure 4 on page 31).
The MG-PMD85 can also be mounted using
the Paradox Swivel Mount Bracket (469). The
swivel mount may allow for easier mounting. If
using the swivel mount, it is recommended that
you seal the space where the swivel mount is
connected to the back cover with some silicon
or with a rubber gasket to ensure that moisture
does not enter the detector.

PCB Height Adjustment
The MG-PMD85 is designed for optimal
performance at a height of 2.1m (7ft), but can be
installed lower or higher. After you have installed
the detector, ensure that the adjustable height
markings on the upper right of the PCB’s cover
inside the unit match the installation height.
For example, if the detector is installed at a
height of 2.1m (7ft), the PCB should then be
adjusted to 2.1m (7ft). Align the desired marking
(height) with the back cover’s plastic tab (Figure
1 on page 28 and Figure 2 on page 29).
If another installation height is called for, readjust
the PCB accordingly. Any PCB adjustments
should be followed by a walk-test of the
protected area. Walk-testing verifies that the
required coverage is in place.
Ensure that the unit’s front and back cover
are tightly joined together without any
spacing (around the rim of the unit) before
tightening the screw, otherwise the
weatherproof casing may be compromised
and moisture may enter the unit.
LED Setting (DIP 1)
This option enables or disables the red LED. The
red LED will illuminate for a period of four
seconds to indicate detected movement. The
motion detector performs a battery test every 12
4 Magellan MG-PMD85
hours. If the battery voltage is too low, the red
LED will flash at eight-second intervals and the
motion detector will send a low battery signal to
the receiver. A trouble will then be generated and
transmitted to the central monitoring station. The
red LED will flash rapidly when the motion
detector transmits a signal to the receiver.
DIP switch 1 OFF = LED deactivated
DIP switch 1 ON = LED activated (default)
Single/Dual Edge Processing (DIP 2)
This option determines the DSP (Digit a l Si gn al
Processing) of the detector. Single Edge
Processing should be used in normal
environments with minimal sources of
interference. Dual Edge Processing provides
better false alarm rejection if the detector is
placed near sources of interference that can
adversely affect it.
DIP switch 2 OFF = Dual Edge
DIP switch 2 ON = Single Edge (default)
DIP switches 3 and 4 are reserved for future
use.
Reference & Installation Manual 5n
Powering the Detector
1. Insert three “AA” batteries into the bat te ry
holder while verifying polarity. Refer to Figure
2 on page 29.
2. Insert the battery holder into the back cover
and affix the battery cable to the battery
connector on the PCB. Refer to Figure 3 on
page 30.
After connecting the battery cable, a power-up
sequence will begin (lasting between 10 to 30
seconds). During this time, the red LED will
flash and the detector will not detect an open
zone or tamper.
Replacing the Batteries
1. Disconnect the battery cable from the battery
connector of the PCB.
2. Remove the battery holder from the back
cover and remove the old batteries.
3. Press and release the tamper switch to
ensure that the unit has powered down.
4. Follow the steps outlined in Powering the
Detector above.
Sensitivity Settings
MG-PMD85 features adjustable sensitivity.
Adjust from 1 to 10 where 1 is the lowest setting
and 10 the highest. Remove the front cover and
with a screwdriver, turn the trimpot clockwise to
increase the detector’s sensitivity or
6 Magellan MG-PMD85
counterclockwise to decrease it. You can turn
the trimpot 360° in both directions.
Depending on the sensitivity setting, an
alarm condition can be generated between
0.25 sec. (highest) and 2 sec. (lowest) after
the actual movement.
Viewing Sensitivity Settings
Remove the cover to view how many times
the LED flashes, then adjust the setting
accordingly. The LED flashes a consecutive
amount of times to show the setting. Thus if
the sensitivity is set to 6, the LED flashes 6
times. If no action is performed after three
minutes, the LED will exit sensitivity display
mode and return to its normal operation.
Walk-testing
At 20°C (68°F), open and close the cover to put
the detector into Walk-Test mode. The Walk-Test
mode will stay active for three minutes.
At the highest sensitivity setting and in Single
Edge Processing mode, you should not be able
to cross more than one complete zone
(consisting of 2 beams, left and right sensor
detecting elements) in the coverage area with
any kind of movement; slow/fast walking or
running.
Reference & Installation Manual 7n
At the lowest sensitivity setting, the amount of
movement required to generate an alarm is
doubled. The approximate wid th of a full beam at
11m (35ft) from the detector is 1.8m (6ft). To
walk-test, move across the detection path, not
toward the detector.
After a power up, the detector will au tomatica lly
enter Walk-Test mode for three minutes.
Signal Strength Test
In order to verify the receiver’s reception of the
motion detector’s signal, perform a signal
strength test before finalizing the installation of
the MG-PMD85. Prior to performing the test,
make sure that the batteries have been inserted
into the battery holder to power the detector. Also
verify that the motion detector h as been
assigned to a zone. For more information on
signal strength tests and zone programming,
refer to the appropriate receiver’s Reference & Installation Manual. If the transmission is weak,
just moving the detector by a few inches can
greatly improve the reception. If the signal is still
weak, it is recommended that the detector be
moved to another location.

Alive Software
If the motion detector transmits two alarm signals
(LED on for 4 seconds) within a five minute
period, the detector will fall into Energy Save
mode where the detector will not transmit any
alarm signals for approximately 3 minutes. Due
to the motion detector’s Alive software, the red
LED continues to flash to indicate a detection
even when in Energy Save mode. Once the
three-minute Energy Save mode ends, the
detector will return to normal operation.
If the detector’s cover is removed and then
replaced while in Energy Save mode, the first
detection will trigger an alarm signal.
