1. Introduction
AN-102C is a domestic photoelectric smoke detector with LoRaWANTM compliance.
It can detect smoke generated by fire and send alarm signal in time. The alarm adopts
photoelectric smoke sensing device and excellent production technology, with stable
work performance and beautiful appearance. The alarm is powered by 3V lithium
battery with low power consumption, self-check function and low voltage warning
function. It’s stable and reliable, and meets the international "independent smoke fire
detection alarm" technical requirements.
Application
Suitable for families, schools, nursing homes, hotels, factories and other types of
indoor fire safety alarm monitoring. Used to detect fire smoke from wood, cotton
fabrics, plastics and hydrocarbons and etc.
Unsuitable installation site:
A. places where dust, powder, and water vapor are present in large quantities
B. places that may produce corrosive gases
C. Garage, kitchen and places where smoke stays normally
D. places with excessive temperature and humidity.
Feature
Support LoRaWANTM
Detector head and mounting base design

3. How to work
Smoke detection system
The whole smoke detection system consists of AN-102C photoelectric smoke detector,
LoRa gateway, cloud platform and application management platform. Users can also
use their own platforms which must be LoRaWANTM compliant.
AN-102C
AN-102C is a domestic photoelectric smoke detector with LoRaWANTM compliance.
It can detect smoke generated by fire and send alarm signal in time, and report
through gateway to platform.
LoRa gateway
The gateway is connected with AN-102C through LoRa communication technology. It
is connected to the Internet through Ethernet or wireless cellular mobile network to
backhaul data to the cloud platform.
Cloud platform
As to LoRa network server, we can provide our LoRaWAN middleware platform,
customers can deploy the middleware locally on their server or on Cloud, and the data
is in their hands, we'll provide them with API interface and MQTT message
subscription, and if they’ve already had their own application platform and want to
get LoRa data, they can get LoRa data by MQTT message subscribing with our
LoRaWAN middleware platform; If they haven’t had their own application platform,
they can develop their own based on our LoRaWAN middleware.
Operation:
Turn on: Take out smoke detector, take out yellow plastic piece, the device is turned
on.
Join network: Ensure that the frequency points of the node and the gateway are
consistent, and the node has been added to the platform, and will automatically join
network after powered on;
Indicator: When the device is working normal, red LED indicator flashes per 53
seconds. When the smoke alarm is triggered, red LED indicator will flash
quickly.
Buzzer: When the smoke alarm is triggered or you are doing self-check, the
smoke detector will emit urgent "beep-beep" call; When the voltage is low, the

AN-102C Photoelectric Smoke Detector User Manual

red indicator will flash every 53 seconds, and the buzzer will beep shortly.
Test: Press the self-check button and hold it for more than 1 second. The red LED
indicator will flash quickly and the buzzer will beep, which indicate the device is
working normal. Release the self-check button, the device will be back to normal
working status. It is recommended to test at least once a month. Please be careful
not to test with open fire. Once the alarm goes off, please pay attention to it.
Alarm: When the smoke concentration reaches the set value, the red indicator of
the alarm flashes rapidly and gives out a "beep-beep" sound. When the smoke
concentration is below the set value, the alarm returns to normal operation.
Hush: Please note that the mute function is used when there is no fire. In the case
of known non-fire alarm, do not block or block the alarm in any form. Press the
self-check/mute button to reduce the sensitivity and temporarily quell
unnecessary alarm.
Low voltage warning: When the battery level is below the set value, the red
LED indicator will flash once every 53 seconds, meanwhile the buzzer will beep
once. The smoke detector is with battery low-voltage detection function. When
the battery voltage is lower than the set value, the red indicator light of the alarm
will flash once every 53 seconds, and the buzzer will beep briefly. Pressing the
self-check/mute button (release within 1 second) will cause the low voltage
prompt to mute for about 12 hours. During the muffling process, press the
self-check/mute button twice continuously (release it within 1 second) to restore
the low-voltage prompt sound.

Battery replacement
Remove the device from the mounting base first.
Remove the inside module from the device, take out the battery, press and hold
test/hush button for 5 seconds and then release, so that the device can discharge
remaining power, or it may send a low battery power fault warning.
Replace with a new battery, and insert the module back to the alarm, push the
switch to power, the red LED indicator will flash once, indicating the device is
powered on successfully.
Press test/hush button, if the device does self-test and sends alarm signals, it
indicates the device is working normal. Push the switch to off position, and rotate
the device back to the base.
