Section 1

General Description

The Model ID20 is a motion sensor/vehicle
detector designed to trigger the operation of an
automatic industrial door. The main difference
between the ID20 and other motion sensors is that
the ID20 will respond to motion moving in only one
direction. The ID20 generates a very low power
microwave beam aimed to cover the same area
normally covered by one or more loop detector
systems. It is less expensive to install and less
susceptible to damage and malfunction from ice,
salt and heavy vehicular traffic.

The ID20 has an approximate pattern size of 18.5
feet wide at 60 feet long from the unit. The pattern
is adjustable by turning the range potentiometer
mounted on the PC board (see pattern drawing—
Figure # 2).

The ID20 operates on much the same principle
that police radar uses. These units transmit a low
power microwave signal, some of which is
reflected by a moving target, such as a forklift or
truck. This received signal goes through a Doppler
shift, a slightly different frequency than was
transmitted. Larger vehicles, such as semi-trucks,
reflect more energy than automobiles and can be
detected at further distances. Since the ID20 uses
microwave signals as its means of detecting a
moving target, it is not affected by air motion,
temperature and humidity changes, or high
frequency sounds.

Wiring - (see wiring diagram—Figure #1)

Operating voltage is 12 to 24V AC or DC and is
usually supplied through a transformer. Current
consumption of the unit is 0.075 Amps @ 24VDC

NOTE: Transformer is included.

Remove four (4) hex head, self tapping machine
screws, two on each end of the sensor, allowing
the enclosure cover to be lifted off, exposing
the terminal strip. When wiring the ID20, apply

power to terminals 1 and 2. The relay contacts on
terminals 4 and 5 are normally open (N.C.) and
terminals 5 and 6 are normally closed (N.O.).

NOTE: When power is applied, allow 30 seconds
of warm-up before testing the sensor.

MS Sedco suggests the use of 4 conductor
cable, 18 to 22 gauge conductor size, 3/16” to

5

/16” cable O.D.

If 22 gauge wire is used to connect the ID20, add
the following:

1. Install a 24V, 40VA transformer, instead
of the 12V, 10VA transformer that is
furnished, for long wire runs (300 feet
or more).

2. Seal the wire fitting with sealant. This
connector is designed for wire with a
jacket between 3/16” and 5/16” OD to
make a good fit in the power grip
connector.

Section 2

Installation

The ID20 vehicle sensor can be mounted for side­fire or overhead detection. The typical mounting
height is 12 to 18 feet. The sensor is mounted
with 2 lag bolts through 2 - ½” prepunched
mounting holes. To remove the fastening bracket
from the sensor, take out the ¼-20 bolt holding the
bracket to the hinge. Using the bracket as a
template for locating screw holes, drill the pole or
band the bracket and refasten the sensor to the
bracket with the ¼-20 bolt removed earlier.

3. No wire larger than 18 gauge can be
used. The terminal block is not large
enough to accept wire larger than this.

Alignment

Align the ID20 motion by adjusting the range
potentiometer and the aiming angle. The range
potentiometer allows the detection pattern to be
expanded or contracted to cover the traffic lane.
The hinge adjustment allows the sensor detection
pattern to be aimed toward the desired detection
zone.

To adjust the sensor’s head angle, loosen the 8-32
lock screw and the ¼-20 hinge screw. This allows
vertical movement of the ID20 motion sensor.

When the pattern adjustment is completed, ensure
that all bolts and screws are tightened.

Operation

An LED is located on the main circuit board and
provides a visual indication as to how the unit is
operating. The wiring and adjustment
specifications (Figure 1) show the location of this
LED indicator. The LED will illuminate when the
relay has changed state in response to motion.

System Inspection and Instructions

*****EXTREMELY IMPORTANT*****

After final set-up, test the unit(s) completely to be
sure that it is functioning properly, as specified in
this manual.

After the installation and operational check of the
system:

1. Instruct the owner of door system operation
and how to test it. This should be checked on
a daily basis.

2. Instruct the owner on what to do if the door or
any of its components become damaged.

3. Strongly recommend to the owner that the
complete entry be inspected twice a year as
part of the service agreement.
