100m Linear Infrared Beam Smoke Detector Smart Reflective Optical Beam Smoke Detector with Reflector
Quick Detail
- Minimum order:1
- Place of Origin:China
- Operating Voltage:20 V to 28 V DC
- Current Parameters:Standby: 23mA Commission: 56mA Alarm: 33mA
- Alignment Guide:Laser Beam Pointer
Specifications
The Laser beam pointing accurately point the exact
location where to mount mirror and with additional digital guide display allows to monitor and guide
on the actual light intensity between the mirror and detector which cannot be seen by our naked
eye making it more easy and convenient in alignment commissioning.
The TX7130 has four adjustable operational ranges of between 8 to 20, 20 to 40, 40 to 70 and 70 to
100 meters beside with three adjustable sensitivity setting ranges from 2.6dB, 3.8dB and 5.8dB to
meet the specific environmental requirement. The TX7130 works on the principle of reflective infrared
beam obscuration. Used in conjunction with a reflector, it will notify the fire alarm panel when the
infrared beam is obscured by smoke.
The detecotr is ideal for use high ceiling and wide areas such as warehouses, large storages, shopping
malls, leisure centres, exhibition halls, hotel lobbies, printing houses, garment factories, museums and
prisons, as well as places where slight smoke particles or corrosive gas exist.

The detector reflective optical beam smoke detector incorporates a light transmitter and the detector
on the same unit. The light path is created by reflecting light emitted from the transmitter off a retro
reflector, meaning it is reflecting light back to its source with a minimum of scattering, which is
placed opposite the detector.
In a fire, when smoke falls within the path of the beam detector, some of the light is absorbed or
scattered by the smoke particles. This creates a decrease in the received signal, leading to an
increase in optical obscuration. This unit decodes or analysts received signals and compare to the
pre-programmed algorithm stored on the processor. Through this algorithm the detector will decide
whether fire is defined or not and lead to enablement the corresponding relays and LED indicators.
The unit on the operating mode maintaining continually emitting light, care should be taken that the
activities in the space do not obstruct the beam or move the device to avoid false operation of the
detector.
