Model DA-500 Information and Most Common Accessories
Drive-Alerts are perfect for use in residential driveways, on farms, at drive-up windows,
in remote locations, and to protect valuable assets and equipment such as tractors or
construction vehicles. The Drive-Alert will detect a vehicle approaching, or whenever a
vehicle or metal equipment is moved.
Drive-Alerts detect metal which contain iron. It will not detect copper or aluminum.
The Drive-Alert’s method of operation is to sense the change in the magnetic eld. This
eld is always present, and is disrupted when a metal object moves through it.
The key element in the Drive-Alert installation is to locate the sensor/probe in the area
where you wish to detect this change. The usual installation is near the entrance of a
driveway, but located far enough away from roads or streets so as not to detect trafc.
Moving ferrous (iron) metal trips the sensor. Larger metal objects are detected easier
than smaller. Faster moving metal objects are detected easier than slower. Metal moving
nearer the probe is detected easier than metal moving farther away. These are the three
factors which determine the system’s range of detection. Therefore, trucks traveling 65
mph can be detected up to 50 feet; cars moving 5 mph up to 12 feet.
The Control Panel houses the electronics which allows the Drive-Alert to function. It also
contains an annunciator, and the terminal strip permits the attachment of the probe as
well as accessories or other devices. Adding a DA-500LKA Accessory adds even more
extra terminals for additional devices.
Longer lengths of cable are available. Simply order a DA-500CP (control panel only)
and a DA-051-___ where you ll in the blanks for the amount of cable needed in 50-foot
increments. Ex: DA-051-250 is a sensor with 250 feet.
A Hard-Wired DA-655 Chime with Volume is the most popular accessory for the
DA-500, and is HIGHLY recommended for all business, drive-up window, and high-
trafc areas where a DA-500 is used. The chime is far more pleasant than the standard
whistle inside the DA-500 Control Panel, and the volume control makes it far more
versatile.
The DA-505 and DA-505W Hard-Wired Timer Control units are housed in a separate
box and attached by wires to the terminal strip on the DA-500 Control Panel. This Timer
Control turns on lights for an adjustable period when a vehicle is detected.
The Hard-Wired DA-052V is and additional alert whistle accessory.
Wireless chimes are available with the DA-066MP Chime Transmitter which easily hooks
up to the contacts on a DA-500 and triggers DA-078 Wireless Chimes
Wireless light control is available with the DA-606LK with timer control.

The Control Panel is generally located in a closet, utility room, or garage. 120VAC power outlet must be available. If the only alert used
is the one contained within the control panel, the panel must be located where users can easily hear the “whistle.” Accessory chimes are
available. The control panel is not suitable for outdoor installation. The ease of routing the three-wire cable from the sensing probe should
be considered when deciding the location of the panel. The control panel is usually attached to the wall.
Improper installation is the No. 1 reason for system malfunction. Please use caution when installing the sensing probe to assure a properly
operating Drive-Alert.
The probe’s sensor is a coil of wire wrapped around an iron rod. Its DC resistance is 700-1100 ohms. The red and black wires connect to
the coil. It is encapsulated in epoxy to protect it from physical damage and moisture.
DO NOT CUT OR NICK THE CABLE JACKET!
If moisture enters, false alarms will be the result!
Mier HIGHLY recommends burying the cable within 1/2-inch PVC pipe for added protection to the cable.
The cable is made with an extra thick outer cover. There is a foil wrapper surrounding the red and black wires. There is a silver (bare) wire
in the foil. False alarms will occur if moisture gets into the foil wrapper. Nicks in the outer cover and improper splices allow moisture to
enter the cable. As moisture enters the cable, the resistance decreases. Resistance between the red or black wire to the shield wire must be
innite. (Use meter with ability to read resistance above 20 million megaohms).
The ideal installation is without any splices. The use of cable other than that which is designed for the Drive-Alert is undesirable and voids
the warranty. Improper splices and unsuitable cable are major causes of false alarms. If splicing is unavoidable, splice the cable using Mier’s
DA-054 Splice Kit, or equivalent.
The sensing probe does not know if it is in or out of the ground, but it must remain absolutely motionless. Most sensors and the direct burial
cable are buried 6 to 8 inches deep and parallel to the driveway. IT IS HIGHLY RECOMMENDED the sensor and the cable be buried in
PVC pipe to protect them over time from rocks migrating up or down in the ground, or landscaping mishaps.
The probe responds to changes in the magnetic eld around it. The signal produced by the coil is a few micro volts for a fraction of a
second. The probe and cable must not be within 20 feet of electric wires because they have changing magnetic elds of their own. Never
bury the sensor in the same trench with other electrical wires, including telephone wires and wires for lights, bells, etc.
The usual installation of the sensing probe is parallel to an already existing driveway. In this case, the sensor probe and cable can be buried
6 to 8 inches deep below the grass line, recommended in conduit. However, if vehicles are going to travel directly over the probe and
cable, they should be buried deeper (see next paragraph).
The burial of the probe is ideal in the center of the area being monitored, but often is not practical. If a new driveway is being put in, the
sensing probe could be buried a minimum of 12-24 inches deep. The sensor and cable should also be protected whenever vehicles move
over it.
You may wish to place a sensing probe atop the ground in the general area of where you wish to bury it, and connect the cable to the
control panel. **This will allow you to TEST the system in application BEFORE nal installation.** It would be acceptable to leave the
sensing probe and cable above the ground for a couple of days, but make certain it is not damaged during this period, and that it is held in
place so it will not move. This method should not be used permanently. See OPERATIONS INSTRUCTIONS for adjustments which may be
necessary.
The sensing probe may be placed up to 5,000 feet from the Control Panel. Up to 3 sensing probes can be attached to one panel, but each
additional probe reduces every probe’s sensitivity and the distance it is able to detect. The Drive-Alert will not know which sensing probe
detects a vehicle. If you wish to use “Zoning” with different alerts for different areas, consider a Mier DA-100 or DA-700 Drive-Alert
System.

Keep the probe, cable, and control panel at least 8 feet away from heavy power lines, power
panels, motors, arcing or sparking machinery, and radio transmitters. In some cases, moving the
panel and/or cable a few feet can solve interference problems. FIGURE 1 illustrates the contacts on
the bottom of the DA-500 Control Panel, with the sensor correctly attached.
When more than 1 probe is used, wire the units in parallel at the terminals on the DA-500 control
panel. DO NOT CUT/SPLICE the cables: doing so may allow moisture from entering the cable and
causing problems such as false alarms. (See FIGURE 2) The sensing probe is a 1x12 inches
cylinder containing a sealed sensor.
Be cautious when handling the
sensor and particularly careful to not
nick the cable attached to it.
Bury the probe at least 6 inches deep.
A typical installation is the probe 6
inches deep parallel to drive, which
will allow the probe to “sense” 12
feet across the driveway.
The ideal installation allows you
to extend your detection range by
installing the sensor under the center
of drive.

Operation and Adjustment Instructions
The Drive-Alert is adjusted at the factory for maximum sensitivity for the probe and minimum time for the whistle. To adjust these, open the
control panel and adjust the small pots according to the diagram on the inside cover (see FIGURE 2). The whistle “timer adjust” is
adjustable from 1-12 seconds and the LED 3 will light.
When rst plugged in, the red blanker LED 2 will remain on for only 1 minute, and the Drive-Alert will be muted for approximately 1
minute each time the electrical power is turned on. It provides time for the electronic circuits to initialize.
During normal operation, the noise blanker detects unwanted electrical interference and mutes the Drive-Alert for a few seconds. It has
been adjusted at the factory. The blanker light should be off during normal operation.
To test the Control Panel, it is possible to rub your nger simultaneously on the three terminals to which the sensing probe is attached. This
should cause the system to go into false alarm. This will occur with or without the sensing probe attached. Be sure the terminal screws are
tight while making the test. If the system responds to this test, in almost all instances it indicates a properly functioning control panel.
If false alarms occur, remove the sensing probe wires fron the Drive-Alert terminals. Let the power remain turned on to the control panel.
If the false alarm stops, then the most likely cause of the problem is moisture in the sensing probe cable. Radio transmitters, cell phones,
cordless phones, and wireless modems within 10 feet of the control panel may cause false alarms.
Additional devices can be attached to the Drive-Alert on its terminals at the bottom of the control panel. When the whistle switch is turned
off, the Drive-Alert terminals can switch customer provided electrical current up to 5 AMPS. Never attach any device that puts more than 30
volts DC on the Drive-Alert terminals. When the whistle switch is turned on, the Drive-Alert terminals have available 24 VDC at 100 MA.
Refer to the diagrams in this manual for hookup instructions.
Mier Products has a hard-wired “timer control” accessory available. The DA-505 Timer Control attaches to the Drive-Alert terminals. This
Timer Control is adjustable from 45 seconds to 45 minutes. It switches up to one thousand watts of 115 volt power for outside lights. Mier
Products also has a hard-wired chime available. The DA-655 Chime with Volume Control is the most popular accessory for the DA-500,
and is highly recommended for drive-up window or business applications. Mier also has a wireless “timer control” kit (DA-606LK) which
adjusts from 45 seconds to 45 minutes and includes a DA-071 Light Switch and DA-072 Lamp Module to control lights as an alert in addi-
tion to the audible alert. Furthermore, Mier has a chime transmitter (DA-066MP) which triggers wireless DA-078 Wireless Plug-in Chimes.
NOTE: When using multiple accessories, add a DA-500LKA which provides additional relay contacts to a DA-500.
Along with Mier’s accessories, the DA-500 can also trigger your other devices such as surveillance, bells,
sirens, signs, gates, and much more!

DA-500 Drive-Alert Frequently Asked Questions
Q: How many Sensor/Transmitters can be used?
A: Three hard-cabled sensors. However there is no way to discriminate which Sensor/Transmitter is causing the alert to sound.
Q: How many sound devices can be used?
A: See the following list and quantities supported:
•DA-063 8 inch Bell QTY 2
•DA-052V Hard-Wired Remote Whistle QTY 5
•DA-078 Wireless Plug-InChime QTY Unlimited
•DA-071 Wireless Light Switch QTY Unlimited
•DA-072 Wireless Lamp Module QTY Unlimited
•DA-655 Wired Chime QTY 3, with a maximum of 50 feet of wire
•Miscellaneous Sounder QTY # That adds to 100mA(max) load
Q: Does the unit have the capability when it determines an alarm is to be sounded, to trigger another device.
A: Each unit DOES have this capability as the 3 contacts from the alarm relay are available for use at the Terminal Block (Terminals 6-8). In models
that DO have an internal Whistle and corresponding switch these contacts normally switch +24 Volts but can become Form C dry contacts when
the Whistle Switch is in the OFF position. In those models that DO NOT have an internal Whistle, and corresponding switch, these contacts will
always be switching +24 Volts.
Q: Can a camera be activated by the Drive Alert.
A; Yes, by using the Form C dry contact mode or by buffering with an external relay in the non-dry contact mode.
Q: Can a gate be activated by the Drive Alert.
A: Yes, by using the Form C dry contact mode or by buffering with an external relay in the non-dry contact mode but safety care should be taken
for the event a person or vehicle in the gate’s path.
Q: Can vehicles be counted using the Drive Alert.
A: Yes, by using the Form C dry contact mode or by buffering with an external relay in the non-dry contact mode.
Q: Can the Drive Alert provide a contact closure for detection to open/lift an arm and then close it when the vehicle has cleared the area.
A: No, it does not provide intelligence beyond the simple sensing that the magnetic eld has been disturbed. Once disturbed a closure occurs for
a user dened time up to 12 seconds at which time the gate or arm will then return to its home position. For these types of functions external logic
and timing is required.
Q: Can the Drive Alert sense which way the vehicle is traveling?
A: No, it does not include this capability and would require either external methods or the use of two systems and most likely external logic to
sequence the two systems for this determination.
Q: How can I determine if something NOT a magnetic metal is moving?
A: Within the range of the sensor, attach a magnet or a metal that has magnetic characteristics such as steel. Now whenever it moves the sensor
senses it, transmits to the Receiver/Control Panel and the alarm is set off.
Q: Does the Drive Alert sense people?
A: No, it doesn’t sense people or animals, only changes that result in a magnetic eld disturbance. IF detecting people or animals is needed with a
Drive Alert, then a magnet or signicant magnetic metal must be on the person/animal.
