1. Wireless fire alarm smoke detector
introduction
1. BR704 Photo-electric smoke detector introduction
JTY-GW-BR704 Standalone photo-electric smoke detector use special structural design, can
quickly and effectively detect a fire smoldering stage smoke. When the smoke enters the detector,
light scattering, light receiving element to detect light intensity, when light intensity reaches a
predetermined value, immediately issued signal to the photoelectric smoke detector fire control
panel.Meanwhile , sound and light alarm receive alarm signal .

2.BR708 Photo-electric smoke detector introduction
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.

4. 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-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.

3.Control Panel Introduction
BR-ZN-WG810 Standalone fire alarm control panel （ Rerferred to control panel ） is 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.
3.1 Features

 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.
