The DA-610TO Sensor/Transmitter
comes standard with all of Mier’s wireless Drive-
Alert Vehicle Detection Systems. This sensor detects the movement of metal within 14’ in
every direction, and sends a signal back to the control panel up to 1000 feet away.
See the DA-
611TO below if you are not able to place the sensor right next to the drive, and see the DA-660
to boost the reception range between the transmitter and control panel up to 1/2-mile.
The DA-610TO detection threshold is set by a sensitivity control on the transmitter circuit
board. Maximum sensitivity adjustment is clockwise and minimum is counter-clockwise. In
most cases the factory sensitivity and address code setting will function for the installation. If
a unique address code is needed (e.g. interference from a neighboring Mier wireless system)
open the top cover and adjust the blue and white rocker switches labeled ADDRESS in both
the DA-610TO
AND
the Control Panel so they are different than factory spec and still match.
The DA-610TO should be placed next to the drive or area to be monitored, and at least 40 feet
from any road traffic to prevent false alarms. Reducing sensitivity would reduce detection of
road traffic, but would also reduce the detection sensitivity in the driveway. The sensor can
be placed in any orientation, parallel or perpendicular to the drive.
Any movement of the
sensor will cause an alarm for asset protection.
Transmitting range from the sensor to the
control panel in the home is 500’ if placed on the ground, and up to 1000’ if mounted 2-4’ high
on a post (metal, wood or concrete) or a convenient building. Long-range “LR” Drive-Alerts
include a DA-660 reception booster antenna and increases this range up to 1/2-mile!
If occasional false alarms occur, reduce sensor sensitivity by turning the small brown
sensitivity control slightly counter-clockwise. Lightning strikes cause a large disturbance in
the magnetic field, so nearby strikes will cause a a false alarm. It is also possible for electrical
current variations in nearby power lines to cause a false alarm.
The DA-611TO Remote-Sensor/Transmitter
is an option which is identical to the
standard DA-610TO with one exception: the DA-610TO sensor is
inside
the transmitter box,
but the DA-611TO sensor
is outside and attached to the transmitter by a 50’ cable
. This
allows the sensor probe to be buried under or next to the driveway or area to be monitored, and
the transmitter box to be hidden up to 50’ away or placed high above ground for better range.
For most installations, the DA-611TO sensor should be buried 6 -12 inches below ground and
the cable 3 - 6 inches below ground. Mier HIGHLY RECOMMENDS burying the cable in
1/2-inch PVC pipe to protect it.
NOTE: Try the system above ground temporarily before burying. The entire system, probe,
cable and transmitter can be installed above ground if there is little risk of probe or cable
damage and the probe cannot move. Any movement of the probe will trigger an alarm.
Both sensors are powered by two AA batteries which last one year in residential applications.
