ON

DIP

A. Press the tache
with a screw-drive

3.3Illustrated Installation Procedure

1

Disassemble unit

C. The PCB out

B. Remove the cover

1.8-2.8m beyond ground

A. Mark the drilling points
and drilling the wall

B. Insert two dowels and
attach the base to the wall

with two screws

C. Insert the bottom edge of

the large PCB under this

TAB & Press the top edge in

Surface

mount

3.5 The code way of detector and the control panel.

Code setting:
Install the battery insulation slice, the LED gives indication..
Please do code program to the alarm control panel at this time. After the
setting of the control panel tamper, press the dismantling switch, Then
the detector will generate deep to indicate successful operation.

Press this switch for code setting

3.6 How to change battery

When the detector batlery is weak, it will send out single

to the control panel, at the same time, the detector

flashes indicating at you need to change battery for the
detector. Draw the PCB board; follow the steps as below to change 4

new battery. ( as right picture ).

3.7

Setting of detection angle

When installing with a swivel bracket
(optional) .please refer to the right
diagram, to ensure the desired
(overage and feature).

At this angle, detection
angle is smallest, sensi-
tivity is highest. Loss pet
immunity function.

At this angle, detection angle is
largest, Lower section sensitivity

is low. Pet immunity up to 20Kg

At this angle, sensitivity
is in middle. Pet immun-
ity up to 10Kg

3.4 Instruction of code switches

1. NO .1switch is for event mode, when set “OFF”, the detector will

alarm when detecting any movement follow input the enacted
directed ;when set “ON”, when it detect movement following the
enacted directon, ut won’t alarm at once, until detect continuous

and keeping on movement, it will alarm (fit for room without passage)

2. NO .2 switch is LED switch, LED light when setting “ON”,during

working

3. NO .3 switch is for direction distinguish, when set “ON”, this funtion

available; when “OFF” ,any movement from any direction will trigger
alarm

4. NO .4 switch is for direction choose, left/right fit for different

surrounding

1.event mode switch
2.LED switch
3.Direction distinguish switch
4.Direction choose switch
