Product Description

TX7130 Conventional Reflective Beam Detector has built in Laser beam pointing and Digital guide display for real user friendly alignment method. 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 TX7130 is ideal for use high ceiling and wide areas such as warehouses, large storages, shopping malls, leisure centers, exhibition halls, hotel lobbies, printing houses, garment factories, museums and prisons, as well as places where slight smoke particles or corrosive gas exist.
  

The TX7130 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.
