Feature and Benefits


EN54-12 Certified

Hassle free alignment, built with digital guide display and laser beam pointing

Employ single-ended design through reflective mirror Four  ranges  wide  monitoring  from  8-100  meters  via encoder

Three users programing sensitivity adjustment Built-in microprocessor

Self-diagnosis function can monitor for internal faults Automatic       compensation        for     factors      weakening received signals, such as dust contamination, positional movement and ageing of the transmitter

Fire and Fault interfacing relays Attractive and pleasing appearance Real User friendly alignment method




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 centres, exhibition halls, hotel lobbies, printing houses, garment factories, museums and prisons, as well as places where slight smoke particles or corrosive gas exist.

Q:What are your thoughts on Stoudemire almost ending his career by punching a fire extinguisher?
this text refers to tickets given to motorists who have not paid for parking which charge above and previous the linked fee of parking. even though, in case you parked in a pay lot and did no longer pay, or parked for longer than your cost allowed, you're nonetheless responsible for the parking cost - merely no longer one greater administration cost. base line - in case you owe the parking cost, you should pay it. in any different case they'd direct a team corporation to get the money, then you definitely could ought to pay greater.
Q:why did my smoke detectors not go off during fire?
ok so you lay your body down on the ground, and just lay under the sun.
Q:what are releasing mechanisums ?
all of them but the fridge. as a JC in the early 60's I participated in Sabin Oral Sundays a precursor to the Salk Vaccine. You got an oral dose of the vaccine on a sugar cube three Sundays in a row as I remember Portable CalculatorThis also occurred in the early 60's as I remember. I remember manual calculators where you turned a crank and moved a carriage to get the answers. Tough to do square roots. They were a boon in my field of agricultural chemistry. Smoke Detectors were also in the 60's. their precursors were heat detectors before my time. One use of a heat detector (Wood's metal triggers on fire sprinklers and fire extinguishers) came in the 30's I beleive. Microwave. First one I saw was at a county fair used to pop popcorn.
Q:What is a fire blanket?
They're literally ping pong balls glued to a green or blue body suit. The technology is all in the computers that monitor their positions and movements.
Q:Does a lightning rod on top of church indicate a lack of faith?
Run down the hill a couple hundred feet and wait it out in the lake
Q:All my fire alarms are going off at once at 1am!!!!?
lmbo lol ghaha im sorry but this is hillarious. but 4 real tell your parents he's bullying you. try to get a cell phone revol wireless is 25/mo unlimited.
Q:Green/Environmental Door Prizes for LEap Day Potluck?
This will sound like a slippery answer, but it all depends on what frequencies of EMF you want to detect. EMF covers everything from Extreme Low Frequency (ELF, or the radio used for submerged submarines), through normal AM and FM radio, up through infrared, visible light, ultraviolet, X-ray and Gamma ray. Visible light detectors are dirt cheap - you have two of them in your head! Infrared is easy - we feel it as heat. A radio detector is another name for a receiver. These can get quite complex and expensive, depending on the frequency. I built an AM receiver using just 50 feet of stretched out wire, one diode and a button earphone. Cell phone frequency detectors will be expensive, however. Maybe you could start doing Google searches to narrow down exactly what you want to do and learn how to do it. There are *a lot* of ready-made schematiccs for most things you can think of. The $5 limit will be a challenge, but who knows?
Q:Ford focus Rims bent caliper?
- Continually laugh at the stand in teacher, simple but very effective. - Hide the register and make up new names for everyone in the class. - Lock the teacher in a cupboard. and so much more!
Q:Is it a good idea to buy a fire extinguisher for my car?
kerosene heaters is not the way to go if it is not ducted the fumes will give you a head ache at the very least
Q:On Poptropica, Super Power Island?
Have you tried to replace your lighter, or just use a regular lighter. 
