LM-101L Fire Detecting Wireless Online Alarm Instruction

1、Brief introduction

LM-101L fire detecting wireless online alarm is a kind of smoke alarm with photoelectric smoke detection and wireless online alarm function，When one of the alarms detects smoke signal, it could send out wireless alarm signal, trigger other alarms alarm(see effective transmission distance) , remind you that there are dangerous cases (fires) happening in time..

2、Characteristic

（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.
