The document introduces a wireless fire alarm system that uses a control panel and smoke detectors. 1) The control panel uses RF technology for stable signals. It can power for 8 hours on backup and send alarms to up to 8 phones with the location and fire point. 2) The smoke detectors use photoelectric sensors to detect smoke and send wireless alarms. They have low power consumption and can work for 2 years on batteries. 3) The wireless system is easy to install without wiring and can send alarms over long distances to quickly notify many people of a fire.

1. Wireless fire alarm system introduction
(BR830)
1.Control Panel Introduction
BR-ZN-WG830 Standalone fire alarm control panel （ Rerferred to control panel） Is my
company relying on the Shandong Provincial Fire Association research and development, for early
warning of fire hazards intelligent fire alarm control panel .It has many advantages such as
multiple alarm, stability, easy operation, and can be widely used in various places or units such as
family, warehouse, residential high-rise, restaurant, hotel and so on.
1.1 Features

1.3 Installation process
 Remove the control panel from the box and put the GSM SIM card into the control panel
SIM card slot.Turn on the power, the screen displays the Beiren Huizhi trademark
interface,after 30 second then the SIM card is registered successfully into the initial interface.
 Wait for the control panel initialization completed and the enter into the initialization
interface，the upper left corner of LCD network shows the GSM network signal
strength.power light and standby light open is standby mode.
 Set the public alarm telephone number, room alarm telephone number, room learning and
other necessary parameter settings according to the setting instructions, The upper right
corner shows the battery status and whether there is an external power supply.
 After setting, return to the initialization interface,tighten the receiving antenna correctly and
then put into use.
 After installation, do a distance patch test to check the connectivity between the detectors and
the control panel.
 After entering the alarm mode ,screen display “****Room**Unit**Building”have fire . and
voice prompt “****Room**Unit**Building”have fire, and open alarm light,at some time
send an alarm message to 8 saved phone (The first ten seconds of the alam ),and call 8 saved
phone alarm (Received the alarm after 10 seconds,saved the first phone can receive the alarm
call ,and so on.) , open sound and light alarm and wireless switch .

3. 1.4 Silence /exit alarm
In the alarm state,can press the "back" button to eliminate the local sound alarm, can also
press the “hang up “button to exit the alarm.Note in order to avoid frequently enter the alarm
state, Just exited the alarm status in 3S-5S, the control panel no longer receives the wireless
alarm signal.
2 .Smoke detector introduction
Product number:JTY-GW-BR708
Point type photoelectric smoke fire detector(Referred to as detectors)use the principle of
photoelectric smoke detection fire, dedicated single-chip intelligent control.It has many
features such as smoke sensitive,wireless transmitter, no wiring, low power, self-test,
beautiful and durable, stable and reliable.It is a fire alarm device dedicated to the family,
small high-rise residential, hotels and other personnel-intensive places.
2.1 Structural characteristics and working principle
JTY-GW-BR708 detector can regularly exchange information with the wireless fire
alarm control panel to determine whether the detector is working properly.When the detector
fails, the wireless fire alarm control panel can quickly know where the fault occurred.JTY-

4. GW-BR708 detector use a special structure design of the photoelectric sensor and it can
quickly and effectively detect the smoke at early stage of the fire smoldering.When the smoke
enters the detector,then the light source produces scattering and the light receiving element
detects the light intensity.When the light intensity reaches a predetermined threshold,JTY-
GW-BR708 detector issued a wireless alarm signal to a stand-alone photoelectric smoke fire
detector fire alarm control panel(Referred to as fire alarm control panel) immediately.At the
same time it issued a sound and light alarm signal.
2.2 Features
 Supporting the use of two-way series fire alarm control panel;
 Intelligent control of single chip microcomputer;

6.Installation and commissioning
6.1 Install the two mounting holes on the ceiling at 60mm apart, and secure the bottom plate
of the detector with expansion plugs and self-tapping screws.
6.2 Open the alarm cover, install the two 3.6V disposable lithium batteries in the detector,the
buzzer drops several times before detaching the detector back cover.
6.3 Tighten the detector cover and buzzer removal tips to eliminate.Press and hold the self-
test button 3S to enter the learning state,meanwhile use the encoder or fire alarm control panel
send the address to the detector.The detector buzzer beeps once indicate successful l 所
earning.Press the Test button when you are finished.The indicator light flashes and the buzzer
rings to send a test signal.The fire alarm control panel prompts for a test.
6.4 After the detector has been tested, place the detector on the base plate and tighten it
clockwise in place.Normally, the LED flashes once every five minutes, indicating that the
detector is working properly.
Note:
①Install the detector on top of the roof or wall and avoid access to doorways or windows.
②The detector should be installed not less than 30cm away from the fluorescent lamp.
③Avoid installing the detector in the following locations :in the larger dust places, water mist,
steam, oil mist pollution, corrosive gases, strong magnetic interference places.
