4、Appearance and dimension（figure 1）

 

                                                        

5、use

（1）Function diagram of cover base  mounting plate（figure 2）

  

                                                                                                      figure 2

（2）Battery mount（figure3）

a、Take out the product from packing box, rotate mounting plate anticlockwise, take out the 9 V and 1.5 V       battery,remove the protective film on the battery respectively.

b、put 9 v battery into the battery compartment and pay attention to The battery polarity symbol in compartment；

c、Please turn bayonet lock rocker to inwall before put 1.5V battery into compartment and pay attention to The battery polarity symbol in compartment；

d、aim  raised two hooks on mounting plate to two card slot on base .rotate mounting plate clockwise till hooks enter into card slot totally.

（3）Test/Online/Delete memory

 Products entered the normal working state after power on and alarm indicator (red LED) flashes about  every 43s.

 test…

Press the test button ，alarm send out clear loud alarm signal tone，alarm indicator(red LED) is quickly flashing, online/learn indicator (red/green LED)is flashing and send out wireless alarm signal（online products in effective distance)at the same time. It shows that the alarm is in normal working state. We can also adopt artificial blowing smoke rest..

 Set/Online…

Host setting…Take any one of product（online need two or more products），press learn button once,，indicator light（red/green LED）changed once，set host to green indicator state ；

Slave setting…Set other products to red light state.

Online…

1、When the setting is correct,，Press the test button on host and hold it till the alarm indicator (red LED) and online/ learn indicator (red/green LED) flashing continuously, alarm send out wireless alarm signal to around at the same time ；

2、After the slave receive the online signal from host ，learn indicator will flash continuously .the alarms begin

to alarm at the same time and alarm lamp(red LED) is out.

3、After online setting ，take out one of alarms to press its test button ,the rest products will send out alarm and  flash continuously.

 Delete memory…Take one product do not need online. Press it’s learn button to set green state. Press test button to normal alarm state, then alarm indicator (red LED) and online/ learn indicator (red/green LED) flashing continuously, it is means the products had delete current online memory.

6、Installation sketch map （figure4）

（1）Choose a suitable installation position and effective communication distance;

（2）According to the holes of the installation board, drill a hole in the needed place of ceiling and stuff the plastic nail seat into the hole;

（3）Use the screw to fix the installation panel onto plastic nail seat;  

（4）Embed the two detector base hook into the detector slot. Turn the smoke detector clockwise in order to fasten it to the installation panel tightly.

（5）After installation, carry out the actual communication test to prevent the communication fault.

7、Maintenance

（1）It is better to test the smoke alarm weekly.

（2）Clean the alarm every three months. When cleaning, take out the battery. After finishing cleaning, press the test key to check the online condition.

（3）If you find the products are not in normal working state, check the battery first. If the problem can not be removed, please do not dismantle by yourself. You shall seek the service of the professional.

8、Failure analysis and elimination

failure phenomenon	analysis of causes	elimination method	remark
no response of the TEST key	9 V batteries are not installed correctly	Pay attention to the polarity and correctly install 9 V batteries.
no response of the LEARN key	4.5V batteries are not installed correctly	Pay attention to the polarity and correctly install 4.5 V batteries.
Make transient alarm sounds about every 43 seconds.	9 V batteries’voltage is low	Change 9 V battery
Make transient alarm sounds about every 60 seconds.	4.5V batteries’voltage is low	Change 4.5V battery

9、Points for Attention

（1）Do not install the product in the following environment such as hyper thermal, humid, dusty, kitchen, bathroom and so on;

（2）When installing, pay attention that there shall not be objects which will shelter from flash and block making sounds in front of the alarm.

（3）Install several online products to prevent them exceeding effective communication distance or objects which will block communication.

10、Points for Abandoned Products

（1）The packages are made up of renewable matters and please use them as circularly as possible;

（2）The batteries and waste electrical appliances that have been used can not be abandoned with normal household garbage.
