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.
