ACCESSORIES
The LS-30 system includes a full range of accessories, so you can
customize many feature of your security system.
All the radio transmitters used in the LS-30 system, except the Remote
Controller, have a unique random code that is set by the factory with
16,777,216 combinations in total. Also with specially designed
transmission timing control, the LS-30 system can effectively prevent
mutual interference from other transmitters in the system. The Remote
Controller uses copy-preventing hopping-code technology, changing its
radio code every time you press the button. The combinations possible
through this hopping-code are up to 7.3 X 1019. To comply with the
regulations in most countries, radio power is limited to below 10mW, and
effective range is about 100 meters measured at open field. The range may
be somewhat less indoors, depending on the layout of building construction
and furniture.
You may enroll all the wireless accessories and change their related settings,
either through the guidance of the interactive LCD display on the Base Unit
explained in the “INSTALLATION” section that follows, or by using a
computer with the proprietary software “HyperSecureLink” through an
interface adapter, which offers a quicker and simpler way to perform the
installation in.
NOTE: The changes or modifications not expressly approved by the
party responsible for compliance could void the user’s authority to
operate the equipment.
The comply with the FCC RF exposure compliance requirements, this
device and its antenna must not be co-located or operating to conjunction
with any other antenna or transmitter.
This device complies with Part 15 of the FCC Rules. Operation is subject
to the following two conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
PIR MOTION DETECTOR
INTRODUCTION
The PIR-3SP Passive Infrared Detector detects the movement of human body heat within its
effective coverage; thus, when an intruder crosses or enters the area, the resulting change in infrared
energy from the intruder will be detected and an alarm signal will transmit to the Base Unit.
PET IMMUNE DETECTOR
This detector is immune to one domestic pet up to 18 kg or 60 cm moving on the floor.
If animal activity takes place above 1 meter high, the pet immunity allowance will be
significantly reduced. It is therefore recommended to select a mounting location that can avoid
animal moving within 1.8 m of the detector.
This detector should be mounted on the wall or corner at 2.3 m high and perpendicular to the
floor.
Do NOT use any mounting bracket with swivel adjustment. Should you must use a bracket, it
should be used for horizontal alignment only, do not tilt down.
The weight of the animal can only be used as a reference. Other factors such as height and color
of fur could also affect the level of immunity.
Do NOT aim the detector at stairways that animal can pass.
Place the PCB at the “P” scale position. And Jumper JP5 at “PET” position.
It’s a must to verify the pet immune function after installation. In case animal is detected, sliding
the PCB to -1 or 0 scale to test again.
IMPORTANT NOTE
To get the best sensitivity, PIR should be mounted to detect
movement of the intruder across a room rather than toward the
detector.

Do not install where the detector faces a window, since movement
outside could cause unwanted alarms.
Make sure the detection area does not have obstructions (curtains,
screens, large pieces of furniture, plants, etc.) that could block the
pattern of coverage.
Avoid placing the sensor in areas containing objects likely to
produce a rapid change in temperature, such as central heating
radiators or ducts (or heaters of any kind), air conditioners, open
flame, etc.
INSTALLATION
1. Refer to FIG. 2, and loosen the screw on the PIR bottom, and then remove the front cover.
2. Insert two AAA alkaline batteries. Select “Installer Mode” on the Base Unit and enter the
Installer Code to gain access authority. Then select \Set Device\Enroll Device\Burglar
Sensor\Enter Zone No. to enroll the ID of PIR-3SP by pressing its TEST button on the PIR
board. You may change its various attributes under \Set Device\Change Device Setting\Burglar
Sensor Change, to fulfill different requirements.
Important Notice: In order to reset the microprocessor properly, before replacing the
batteries in the PIR-3SP, press the TEST button for 5 seconds to discharge the energy that
remains in the capacitor on the PC board. Otherwise, it may not restart.
3. After power on, wait one minute for sensor warm-up.
4. Mount the base with two screws (refer to Fig. 4) or use Velcro tab provided at a selected
location, and 2.3m above the floor. Make sure the distance between PIR and Base Unit is within
RF transmission range.

WALK TEST
It is essential to perform a walk test to verify optimum detection coverage. To do this, first hold the
“TEST” button on the PIR-3SP board down for at least 3 seconds, until the LED turns ON→OFF→
ON, then release the button. Afterward, the PIR-3SP enters “TEST” mode for 3 minutes. Replace the
cover of the PIR-3SP, then walk into the detection area at normal speed, while observing the LED
indicator. The LED stays ON normally, and turns OFF when motion is detected. If the detection
pattern is not satisfactory, re-aiming the detector or adjusting the vertical pattern by sliding the PIR
board to -1 or 0 scale to test again.
Notes: 1. For the sake of convenience, the PIR is built in a reed switch; refer to its location on
Fig. 1. You may use a magnet to simulate the function of TEST button without opening
the case. When a magnet is placed close to the reed switch, the PIR responses as the
TEST button is pressed; refer to Fig. 5. And when a magnet is removed, the PIR
responses as the TEST button is released.
2. Test mode can be terminated before the 3-minute timeout by pressing the “TEST” button
again (or use a magnet to approach for a second) until the LED turns OFF. Afterward, it
returns to NORMAL mode.
3. In NORMAL mode, the PIR-3SP activates the transmitter when it initially detects
movement, then disables itself. The unit will resume operation only after about 3 minutes
with no further detection of movement. In other words, if installed in a heavy traffic area,
the PIR-3SP will not transmit until the area has been evacuated for 3 minutes. The
purpose of this feature is to reduce power consumption and prolong battery life.
RADIO LINK TEST
Open the top cover of the PIR-3SP and press the TEST button on the PC Board, or use a
magnet to activate the reed switch, to see whether the Base Unit can receive the radio signal.
PULSE COUNT SELECTION
The PIR-3SP is equipped with a programmable pulse counter that can be set by placing the
jumper on the desired setting (2 or 4). The PIR-3SP automatically overrides to one-pulse mode
while in "TEST" mode.
2 pulses: This setting has high sensitivity of detection. Two pulses should be selected when the
detection range is longer (over 5 m)
4 pulses: Alarm signal will only be sent if 4 pulses are detected within approximately 1 minute.
This setting provides the maximum protection against false alarms caused by all types
of environmental disturbances.
LED ON/OFF SELECTION
To prevent the PIR from being discovered by an intruder, LED can be disabled by putting LED
ON/OFF jumper at OFF position. Nevertheless, the LED is enabled automatically when the
PIR-3SP is in “TEST” mode, even with the jumper at the OFF position.

APPENDIX
The PIR-3SP can be used as a conventional detector (non pet-immune) if changing lens to LN-N
type (refer to Fig 6). And the model no. becomes PIR-3S.
Note: 1. When you use LN-N lens, you must place JP5 at “NORL” position.
2. The detection patter of PIR-3S is as below, and you may adjust PCB scale position to fit
detection coverage, or use bracket IRB-3 to adjust detection coverage. Besides, you may
change the installation height properly.
