Model DA-500 General Information
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 constuction vehicles. The Drive-Alert will detect a vehicle
approaching, or whenever a vehicle or metal equipment is moved.
The Drive-Alert detects any metal which contains iron. It will not detect copper
or aluminum.
The Drive-Alert’s method of operation is to sense the change in the magnetic
eld around it. 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 4 mph up to 8 feet; and a walking
person with steel toe shoes up to 1 foot.
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.
Longer lengths of cable are available. Simply order a DA-500CP (control pan-
el only) and a DA-051-___ where you ll in the blanks for the amount of cable
needed in 50’ increments. Ex: DA-051-250 is a sensor with 250’ of cable.
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 win-
dow, 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.
A DA-505 Hard-Wired Timer Control unit is available. It is housed in a sepa-
rate box and is attached by wires to the terminal strip on the Master Control
Panel. This Timer Control turns on lights, usually outside lights, for an adjust-
able period when a vehicle is detected.
The Hard-Wired DA-052V allows you to add additional alert whistles to the
DA-500.
Wireless chimes are available with the DA-066 Chime Transmitter. This
transmitter easily hooks up to the contacts on a DA-500 and triggers DA-068
Plug-in chimes and DA-070 Battery-powered Portable Chimes.
Wireless light control is available with the DA-606LK with timer control.
The DA-500 includes a
Control Panel, Sensor, and 100 feet
of direct burial cable
