									1. Function
         Alarm Leitin Guard LT2001B, an intelligent high-tec security defence, is safeguard of
factories, markets and families. Combined with infrared detectors and magnetic switches to
discover correctly illegal intruders, with smoke and heat detectors to discover fire, with
liquefied petroleum gas and carbon monoxide detectors to find immediately leak of
inflammable and poisonous gas to guarantee residential and personnel safety. Some more
detectors are assembled to response shock and glass breaking to protect residential safety
thoroughly. If necessary, the button of calling for help for the old, the weak the sick and the
disabled is to be set. Once you use Leiting Guard product in series you will be really at ease
whenever you are at home or go out to travel or work. When an alarm is detected Leiting
Guard drives siren at once (up to 100dB(A)) to threat illegal intruders, and prompts
neighbors to pay close attention to the situation and to offer help. At the same time,
LT2001B dials automatically the phone numbers set in IC beforehand to inform the owner of
the household and residential quarter security center for seeking help in time. If you use
residential quarter computer system, you’ll get more scientific management to distinguish the
kind of alarm and to operate automatic filing etc.
         Alarm Leitin Guard LT2001B with six Defence Districts can be set with different
functions by programming according to customer’s option. The Defence Districts against
illegal intruding can be set individually (i.e. some set-up defence and some removed). When
the owner comes back, he chooses remove defence from rooms (for example, Defence
Districts 1) and set-up defence in the garden (for example, Defence Districts 2). Thus he
can enjoy his life with family members at home. Then he can set somewhere as Defence
Districts 3 and 4 to monitor smoke or gas. Both of them will be on alert in 24 hours. There
are another two wireless emergency buttons against banditry and for medical call. The
function of these buttons is that once it is used, the alarm will dial immediately to give an
alarm report, whether the Defence Districts in set-up or removed state. Emergency button is
suitable for banks, stores or families with old and weak members.
         LT2001B has function of remote control. The owner can call at a distant place to
control the alarm for set-up/remove defence or programming.
         LT2001B is perfectly designed to protect its own system. In set-up state the alarm
will drive the siren when short or broken circuit happens. If a detector’s
signal-wire is broken, the situation can be found out and give an alarm (by siren or dialing).
If commercial AC power open circuit, spare battery inside will provide power for more than
one day’s work. When AC power resumes, spare battery will be fully charged
automatically.

2. Instruction
   2.1 Installation: Alarm Leitin Guard LT2001B can be set on table or installed on wall.
When it is installed on wall, the battery should not be put upside down. The correct way is
the terminal of battery must be in up or side direction, never down ward. Connect telephone
line to the terminal “LINE” which on plate of the alarm, (if no phone line is applied, take
L-TEST Jumper to OFF position); Jumper K1 and K2 are used to keep wire-lined defence
district un-functioned. If Defence District 2 is connected to wire-line detector, as figure 1, K2
should be keep off; After alarm being connected with power AC 220v, get the plug of battery
inserted in “BATTERY” socket on the plate and pull out the antenna. Install the two pieces of
wireless magnetic switches separately on the door/window and its frame. Install (or put) the
infrared detector at a suitable place in the room (avoiding heat, place with a draught or
anything swaying may cause mis-alarm). Then you can begin to set up or remove defence
and do program with remote controller.

     2.2. Arrange defence: press key □ of remote controller, all the defence districts will
be in set-up state.
     In set-up state, LT2001B will detect whether there is any alarm such as “ illegal intruding
“, “ gas leaking “, “ smoke “,”heat “ or “ medical call “ by different detectors. Once there is,
LT2001B will drive at once the siren to send out powerful alarm sound and to dial
automatically the phone numbers set beforehand to make the owner and security personnel in
residential quarter to offer help in time. The phone that receives alarm report (owner’s
mobile or receiving alarm center) can hear the recorded voice alarm. This alarm is to be
confirmed by pressing key 5 twice to stop siren and dialing. If not, siren will stop in 5
minutes automatically (can be set as 20 sec.) and dialing will go on until the alarm is
confirmed.
     When LT2001B dials the phone numbers which set for alarm, dial the first number, if no
one answers the call in 60 sec. (or just pick up but without pressing key 5 twice to confirm
the alarm), then dial the next one until one is picked up and the key 5 is pressed twice. If all
the numbers set can not be put through, LT2001B will dial again the first one, until there is
an answer.
In set-up state, if LT2001B discovers short or broken circuit of the phone line, the siren will
send out warning sound for 1 minute. In the period, whenever there is something wrong to be
detected, it will do so. Once the phone line is recovered LT2001B will return to its phone call
to report alarm.
     2.3 Remove defence: press key □ of remote controller, all the defence districts will be
in removed state.
     2.4 Emergency alarm: press key of remote controller, dial for alarm immediately.
     2.5 Medical call for help: press the button on medical caller, dial at once to report. The
receiving center will notify ambulance.
     2.6 Calling: press key S of remote controller, call the receiving center through your
home phone,
     2.7 Control at a distant place by calling: call home, the bell rings 8 times, the alarm
sends out prompting sound “ du du “. Then input the pass-code, the prompting sound “ du du
“ rings again. Operate as following:
      Press # # * ----- set-up defence ( all the Defence Districts in set-up state )
      Press # # 0 ----- remove defence ( all the Defence Districts in removed state )
      If try to program other functions, give command according to programming
     order.
    2.8 Set-up defence districts individually
This system has the function of set Defence Districts individually(i.e. some districts set-up
and some removed ). Operate as following:
     (1 ) Press simultaneously keys □+□of remote controller (get into programming state ).
     ( 2 ) Pick up phone handset. Hear prompting sound “ du du “. Input command on phone
    to set defence.
        e.g. # # 1 #    ( set-up defence in Defence District 1 only )
            # # 2 # ( set-up defence in Defence District 2 only)
            # # 1 3 4 # ( set-up defencce in Defence District 1 , 3, and 4 )
            ##0         ( all Defence Districts removed )
            ##*         ( all Defence Districts set-up )
Note : After set Defence Districts individually, don’t press key □ or □ of remote
controller. That is the way to keep the function of arranged Defence Districts individually,
because key □ of remote controller makes all Defence Districts removed and key □ of
remote controller makes all Defence Districts set-up.
