DESCRIPTION

The C-200AP and C-200APC are dual-technology sensors intended for use
in residential or commercial applications where small animals may be present.
They feature conventional wide-angle coverage patterns that are insensitive
to dogs, cats, etc. weighing up to about 40 pounds. (For larger pets, a
conventional Pet-Alley Lens is provided.) The C-200AP uses a Form-A alarm
relay; the C-200APC uses a Form-C relay.

BASIC OPERATION

These units comprise a passive-infrared sensor and microwave sensor
housed in a single package. The unit will go into alarm when both PIR and
microwave sensors detect intrusion at the same time. The design is such that
small animals within the coverage area will not be detected.

The PIR section operates by detecting a rapid change in temperature when
an intruder crosses a protected area. When a beam experiences a change
in heat (projected back through the lens), a pulse is generated by the sensor
element. The microwave transmitter sends out short bursts of rf energy, and
the receiver detects changes in the returned signal caused by motion within
its coverage area.

The microwave section is unaffected by visible light, air drafts, or tempera­ture changes (as from space heaters or air conditioners, for example), but is
sensitive to motion. Strong vibrations can be troublesome. Microwave signals
may pass through non-metallic walls and windows. Infrared is virtually unaf­fected by vibration, and will not penetrate walls or windows.

Thus the two complementary technologies provide an inherent immunity to
false alarms. Dual technology is ideal for use in hostile environments. Since
both must trip simultaneously to cause an alarm, installation is easier and
requires less discipline.

PIR ZONE DIMENSIONS

Regardless of the lens pattern selected, or the number of PIR beams
produced by the lens, the relative proportions of beam width, beam height,
beam separation, and zone width always remain the same and are illustrated
in Fig. 1. Note that beam and zone dimensions at any distance may be
calculated by the following formulas.

Beam Width “w”
Beam Separation “s”
Beam Height “h”
Zone Width “z”
Examples:

(in.) = Distance “d” (ft.) x 0.4

(in.) = Distance “d” (ft.) x 0.4

= 2 x Beam Width “w”

= 3 x Beam Width “w”

At 10’, a zone is 8” high x 12” wide.; at 30’, it is 2’ high x 3’ wide.

Fig. 1. Relative Zone
Proportions.

DETECTION PATTERNS

Figure 2 illustrates maximum PIR and microwave detection patterns super­imposed on each other. PIR detection patterns are adjustable, within limits,
both vertically and horizontally (see
for detailed adjustment procedures).

The microwave detection patterns shown are for free space. In practice,
when confined by walls and ceilings, reflected waves tend to flood the area,
providing volumetric coverage. Furthermore, when used in long, narrow
corridors, the effective range may be extended by as much as a factor of 2
due to the guiding effect that the corridor has on microwave energy. Micro­wave detection range is adjustable. Reducing range, however, will reduce all
other dimensions proportionately.

Insensitive Areas

The insensitive area is that area directly beneath the unit wi thin which an
intruder is undetectable. It is shown as a shaded area in the side-view
detection pattern that follows, and assumes that an intruder will be at least 5’
tall and that the protected area is not accessible by crawling or crouching.
The size of the insensitive area will increase as the mounting height increases
(see Fig. 2b). Nevertheless, it may be necessary to increase the mounting
height in order to avoid an object that could obstruct the coverage pattern.

STANDARD LENS

This model uses a standard lens that yields the 18-zone, 40-beam pattern
illustrated in Fig. 2. The coverage pattern is adjustable, within limits, both
vertically and horizontally (see
detailed adjustment procedures). Stacked optical centers provide tall, dense
beam pairs, making beam aiming easier and less critical. Examples shown
herein are typical and will not apply to all cases. Always test the coverage
pattern after the unit is installed (see

ADJUSTING THE COVERAGE AREA
Self Test

The self-test diagnostic simulates motion and tests the PIR sensor, amplifier
and related PIR circuitry, the microwave transmitter, receiver, and associated
microwave circuitry. This test is initiated each time the unit is powered up and
randomly at 11- to 16-hour intervals after the last alarm to assure that the unit
is always in operating order. At power-up, the LED will come on and both the
alarm and trouble outputs will be held “safe”. If the unit is operating properly,
the LED will extinguish after about 1 minute. However, if it fai ls t he self test,
the LED will flash rapidly, indicating a need for service. After the LED goes
out, indicating a successful self-test, proceed as follows.

Lateral Beam Adjustment

PIR beams may be shifted up to 6° in either direction (±

1

⁄2 zone for the

Standard Wide-Angle lens). The left edge of the top lens guide acts as the
index for lens alignment. Figure 5 illustrates the relative positions of the index
and lens alignment notches. To align a lens, proceed as follows. (

Caution:

To prevent soiling, handle the lens only with clean fingers.)

Microwave Range Adjustment

Important!

The microwave RANGE ADJUST control should be set at the
minimum required to achieve the desired coverage. It is set so that the
Walk-Test LED lights when motion is detected at the maximum desired range,
but does not light (motion i s not detected) beyond the maximum desired
range. All tests must be made with the front cover in place.

1. Remove the front cover and install the MW jumper.

2. Set the RANGE ADJUST control at mid position. Replace the cover and

walk-test the unit. (

Allow at least 5 seconds after trip for microwave to

reset.)

3. If the desired range was insufficient, advance the RANGE ADJUST
control slightly clockwise. Repeat the test as necessary, increasing the
RANGE ADJUST control each time until motion is detected at the desired
range, but not beyond. (If the desired range was excessive, reduce the
RANGE ADJUST control slightly (counterclockwise) and repeat this step.)

Return the jumper to the ALARM or LED position after adjustment.

Note:

TESTING THE COVERAGE AREA

After the unit has been mounted and set up, its coverage should be tested

and, if necessary, altered to accommodate local environmental conditions
(within the coverage area). Satisfactory checks may be made using the
Walk-Test LED on the front of the unit. It is recommended that the coverage
area be tested at least once a year.

Testing the Unit

Complete connections to the terminal strip (see

WIRING

). The unit will
require a 1-minute “settling” time to adjust itself to the surrounding tempera­ture. After sufficient time has been allowed, proceed as follows.

Move your hand slowly across the lens to verify sensor operation. With the
PIR jumper installed, the LED will light whenever a beam is disturbed. With
the MW jumper installed, the LED will light as long as motion is detected.
When the LED goes out, no motion is detected.

Test the range of the coverage.

Install the PIR Walk-Test jumper and
replace the front cover. Walk out to the maximum determined coverage
distance, then walk across the f ield of coverage. The LED will remain lit as
long as motion is detected. Repeat this test with the microwave MW Walk-Test
jumper installed. Repeat once again with the ALARM. jumper installed.
Confirm that the LED lights at the maximum desired range,

with the ALARM jumper installed.

Test for environmental disturbances.

The following test is applicable to the PIR section only. There are no

Note:

provisions for testing the microwave section for environmental disturbances.

This test will determine if detection occurs with no human activity in the
protection area. Be sure to make this test with all potential disruptive devices
(heaters, air conditioners, etc.) in full operation. Note that blowing curtains
may be troublesome.

Install the PIR Walk-Test jumper. Leave the protecti on area. If an alarm
condition occurs with no one in the coverage area, temporarily block the entire
lens with a sheet of cardboard or other opaque material. If the alarm condition
persists with the lens covered, it is not caused by an environmental distur­bance, and the system requires attention. (Check for low supply voltage from
the control center, or for an intermittent connection.)

Remove the cardboard (or other material) from the front of the lens. If the
alarm condition reoccurs, turn off heaters, air conditioners, etc. one by one
and note the effects. If the offending device must remain in operation within
the coverage area, try to reposition the device and/or alter the aim of the
sensor slightly to effect a suitable compromise. Bear in mind, however, that
each time the coverage pattern is altered, the foregoing environmental test
must be repeated.

12

Zone Masking

If a workable solution cannot be achieved using the above technique,
selective zone masking will be required. This will deactivate a problem zone
in order to preserve reliable
system operation. Carefully
apply a piece of zone-mask­ing foil (supplied) to the
grooved inside surface of the
lens segment representing
the problem zone to block
signal from the offending de-

vice (refer to Figs. 7 and 8).

Figure 8 illustrates the zone-masking foil supplied. Remove one or more
segments that most closely match the lens segment of the offending zone
and affix to the inside surface of the lens. Note that the foil must be accurately
positioned so as not to affect adjacent zones. (Zone segments may be located
by holding the lens up to the light.) Any oil or grease on the surface of the
lens (or on your fingers) will reduce the adhesive quality of the foil.

Important:

After the foil is properly applied, rub it down against the lens (using the tip of
a ball-point pen, for example) to improve surface contact.

If necessary, re-aim and retest the sensor after masking one or more zones.

Fig. 8. Zone-masking foil.

COMPLETING THE INSTALLATION

The jumper must be in either the
ALARM position or the LED position for
the alarm relay to operate. (If the 4-pulse
mode is selected, both the PIR

and MW

jumpers must be installed.) With the ALARM jumper (or PIR & MW numpers)
installed, the LED will indicate a condition that would cause an alarm if the
system were armed. To extinguish the Walk-Test LED after testing, place the
jumper across the LED terminals. In this position, the LED is di sabled duri ng
normal operation, but is enabled for diagnostic indications.
