4. WIRING MATERIALS AND WIRING METHODS

CAUTION

Do not wire near equipment that is a strong source of noise.

Do not wire in parallel to commercial power supplies or power lines.

Do not use aerial wiring. All of these installation could result in a malfunction.



Power line wiring

For the wiring materials of power input wires, use wires that have a resistance lower than the maximum allowable

resistance found using the formula below.

To simplify the calculation method in this example, the calculation method is described for the condition where the all

detectors are installed farthest from the power supply device (so that the allowable resistance is minimized).

masking is not performed after the warmup function has

ended, the Anti-Masking function may not have been

initialized normally. In this case, turn the power off and

then turn it back on.

Anti-Masking LED may be turned on while the warmup

function is running, which does not indicate a failure.

Vol.1

1. Detection sensitivity selection function

(Sensitivity volume)

The detection sensitivity of the detector can be adjusted.

Range: 50% - 100% - 150%

The default detection sensitivity is 100%.

Operation :

When set to 100%, the detection sensitivity when

walking at 1 m/s in a 35°C environment is 1.5°C.

2. Pulse count function

(Setting switches 1 and 2)

Detection operation is performed by a preset number of

signal inputs.

Function selection : Set the setting switches to select one

of the four types below.

(Default

setting)

Switch 1 Switch 2 No. of signals

On On 1

Off On 2

On Off 3

Off Off 4

Operation

:

The number of signal inputs within 10 seconds

are countered, and if they reach to a preset

count, the detection operation is performed.

When 10 seconds elapses from the last signal

input, the count value is reset.

Normally, when a person passes through a zone,

one or two signal inputs are obtained, but if the

temperature difference is small between the

person and the background of the floor or wall,

only one signal is obtained. Therefore, keep this

point in mind when making the setting.

3. LED indicator selection function

(Setting switch 3)

On : Alarm LEDs 1 and 2 (red) are normally off, and turn

on at detection. (Default setting)

Off : Alarm LEDs 1 and 2 (red) are normally off, and do

not turn on at detection.

4. LED precaution and Anti-Masking LED

indicator

(Setting switch 4)

In normal conditions, the alarm LEDs 1 and 2 are

alternately turned on. (once every 2.5 seconds)

Upon detection of Anti-Masking, the alarm LEDs 1 and 2

start ﬂ ashing simultaneously. (5 times a second)

The alarm LEDs ﬂ ash at different intervals between when

operation is in normal conditions and when Anti-Masking

is detected.

On : The LED alarm is used. This function can be used

even though LED indicator selection is off.

Off : The LED alarm is not used. (Default setting)

8. AUXILIARY FUNCTIONS

1. Detection system selection function

Wide mode

:

Install at a height from 2 to 3.0 m. In the default

setting, the Wide mode is set.

Pet alley mode: Install at a height from 0.8 to 1.2 m.

This is used when large pets may be falsely

detected by the Wide mode.

2. Warmup function

Function selection: This function is always enabled

regardless of the switch setting.

Operation

:

To stabilize the detection function of the detector,

the detection operation is not performed for

about 50 seconds after the power is on. During

the warmup operation, alarm LEDs 1 and 2 (red)

ﬂ ash once a second.

3. Self-diagnostic function

This detects errors in the detector itself.

Function selection: This function is always enabled

regardless of the switch setting.

Operation

:

When an error occurs in the element or signal

ampliﬁ cation unit, alarm LEDs 1 and 2 (red) ﬂ ash

once a second, and continue to send the alarm

output until the power is turned off. In this case,

the device must be replaced.

The detector and the Anti-Masking function do not work

while the self-diagnostic function is running.

4. Tamper function

This detects opening and closing of the lower cover.

Function selection: This function is always enabled

regardless of the switch setting.

Operation

: While the lower cover is opened, the tamper

output is sent.

5. Masking function

If causes of false alarm are in the detection area (such

as trees and outdoor air-conditioning units) and causing

malfunctions, mask the lens to disable that detection sector.

Afﬁ x the masking tape by referring to the zone diagram

shown in "12. Detection Area".

9. OPERATION CHECK ~ WALK TEST

(1) The warmup function runs for 50 seconds after the power is turned on, and the detection operation is not performed.

(The alarm LED ﬂ ashes during this time.)

(2) Once the warmup is completed, walk through the detection area along the potential route of an intruder.



If the alarm LED does not turn on, set the detection area, sensitivity, and pulse count again, and repeat the operation

check.

10. TROUBLESHOOTING

If this detector does not work correctly, be sure to check the supply voltage and polarity. If the detector is still not

working correctly even though power is being supplied properly, ﬁ nd the cause and remedy of the problem by referring

to the table below.

Symptom Cause Remedy

The detector does not work at all.

(The alarm LED (red) does not turn on.)

Sometimes, the detector does not work.

Glass, screen, or other obstacle is blocking

the detection zone.

Move the obstacle, or readjust the

detection area.

The relay cable is not connected. Connect the relay cable.

The intruder does not pass through the

detection zone.

Readjust the detector direction so that the

intruder will pass through the detection

zone.

The detector is activated even though there

is no intruder.

(The alarm LED (red) turns on.)

The detector is near a source of electrical

noise, or the wiring is near a power source

or power line.

Change the installation location.

Change the wiring location.

A sudden change in temperature has

occurred.

Move the heat source or mask the

correspond zone of the lens.

Readjust the detection area.

Sunlight, a car's headlights, or other light

source has entered the background of the

detector or detection area.

Readjust the detection area or mask the

correspond zone of the lens.

Trees, laundry, or other moving objects are

within the detection area.

Remove the moving object from the

detection area or mask the correspond

zone of the lens.

Readjust the detection area.

Change the installation location.

Anti-Masking out remains even when

masking is not performed.

The Anti-Masking function has not been

initialized normally.

Turn the power off and then turn it back on.

The alarm LED (red) turns on, but the

receiver alarm is not output.

The receiver is not in the alarm status. Set the receiver to the alarm status.

The alarm LED (red) flashes (once a

second) continuously.

The self-diagnostic function is activated

due to the detector error. The detector and

the Anti-Masking function do not work while

the self-diagnostic function is running.

Replace the detector unit.

6. Anti-Masking function

This function detects masking performed for this device.

Function selection:This function is always enabled

regardless of the switch setting.

Operation

: When masking is performed for one minute or

more, Anti-Masking is output from AM1 or AM2

on the terminal block.

If the setting switch 4 is ON, the alarm LEDs 1

and 2 ﬂ ash ﬁ ve times a second when masking

is performed for three seconds or more.
