Warehouse Smoke Detectors: Introducing theTANDA TX7130 Beam Smoke Detector
TX7130 Reflective Warehouse Smoke Detectors 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.
Feature and Benefits:
- LPCB Approved, EN54 standard
- Built-in digital guide display & laser beam pointing
- Long distance: 8-100 meters.
- Easy sensitivity adjustment
- Built-in smartt microprocessor
- The self-diagnosis function to monitor for internal faults
- Intelligent algorithm automatic compensation
- Fire and fault-interfacing relays
Adjustable Operational Ranges
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 span and sensitivity can be adjusted through dip switch setting or handheld programmer.
Working Principle
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.
TX7130 Reflective Smoke Detector Applications
The TX7130 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.
Beam Detector FAQ
What is a beam detector
A beam detector consists of laser transmitter, laser receiver and reflectors.
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.
How to test a beam smoke detector
1, Testing Fire Signal:
1.1, Using supplied Opaque/ Translucent materials, cover-on half of the beam detector using the translucent portion of the material. With less than 30 seconds the Red LED [Fire] will turn on steady, indicating fire signal. [the fire alarm relay [HJ1 and HJ2] will latch to normally close]. Refer to Figure 14.
1.2, Remove the testing material and cut the power off for at least 2 seconds to reset the detector.
2, Testing Fault Signal
2.1, Using supplied Opaque/ Translucent materials, cover-on the half of the beam using the opaque portion of the material. Right after the Yellow LED [Fault] turn on, indicating the fault signal. [The fault alarm relay [GZ1 and GZ2] will latch to normally close]. Refer to Figure 13.
How far apart beam detector
According to the coverage of the beam detector, the horizontal interval between two detectors is seven meters.

How to check beam detector
1, During the installation phase, two tests are required to check the correctness of the installation: Testing Fire Signal and Testing Fault Signal
2, In daily use, regular inspections must be carried out as specified. Of course, the equipment itself has a self-checking function, as detailed below:
2.1, Automatic Compensation of Light
When dust exists in the working environment of the detector, the emitting window, receiving window and reflector will be covered with dust, which will affect normal operation. in order to solve the problem, TX7130 has the function of automatic compensation of light. When there is dust on windows, the detector can judge the amount of dust, and compensate the received signal through internal program and circuit to ensure the detector can continue to work normally. The detector gives fault signal when dust on the lens and reflector surface reaches a certain level and light compensation reaches the limit for the detector to work normally
2.2, Self-diagnosis on Optical Signal
The detector has functions of checking emitting, receiving and amplifying circuit. When there is faultwith these three parts of circuit during operation, the detector will generate fault information.
