How often does fire alarm cable need to be supported?

Leave a comment

The answer to this question is not as straight forward as one may think. Fire alarm cables (Power-Limited) can be installed exposed (not in raceway) as long as it is protected against physical damage.

On most installations, a basic rule of thumb to use is that any fire alarm cable installed above 7 feet can be installed exposed; below 7 feet the cables shall be in a raceway.

The National Electrical Code requires that fire alarm cables passing through a floor be sleeved in a raceway up to a height of 7 feet, as described above. This is to offer protection from physical damage to the cable itself. Below we have a picture of an installation at a new office building.

When fire alarm cables enter or exit a raceway that is being used to provide protection against physical damage, NEC 300.15(C) requires that a fitting be used on the ends of the conduit in order to protect the cables from abrasion.

3 Major Benefits of Indoor Fiber Optical Cable

Leave a comment

Fiber optical cable is manufactured to meet optical, mechanical, or environmental performance specifications. It is a communication cable assembly that utilizes one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. The optical cable is mainly composed of optical fiber (glass wire as thin as hair), plastic protective sleeve, and plastic shell. The fiber optical cable generally has no recycling value as it without gold, silver, copper, aluminum, and other metals. The optical cable is a communication line that a certain number of optical fibers form the cable core in a certain manner, the outer is sheathed, and some outer cladding layers, to realize optical signal transmission. That is a cable formed by an optical fiber (optical transmission carrier) through a certain process. The basic structure of the fiber optical cable is generally composed of cable core, reinforcing steel wire, filler and sheath. In addition, there are components such as a waterproof layer, buffer layer, and insulated metal wire as needed.

The Major Benefits of Fiber Optical Cable

Easy Handling

Some communication systems require tens or even hundreds of fibers (such as a metro backbone system). Put fibers in a cable make it very easy to install and maintain.

Protection from damaging forces

Fiber optical cables have to be pulled into place through ducts (outdoor) or conduits (indoor). Pulling eyes are attached to the strength members or cable outer jackets. This is critical for isolating the fibers from the applied pulling forces. Glass fibers cannot endure more than 0.1% to 0.2% elongation during installation.

Protection from harsh environment factors

Cable structures protect fibers from moisture (outdoor cables), extreme temperature (aerial cables), and the influx of hydrogen into the fiber (which causes light absorption peak at 1380nm which in turn impair fibers’ transmission properties).

UTP CAT6 Cables Overview

Leave a comment

Conformed with EIA/TIA/IEEE standards, UTP Cat6 cabling system includes patch cables, pre-terminated trunk cables, and bulk cables. For most first-class suppliers, their UTP Cat6 Ethernet cables, involving UTP Cat6a ethernet cables have 100% passed the Fluke Test, and deliver a specified testing report.

Generally, UTP Cat6 network cables adopt oxygen-free copper conductor with high electrical conductivity and low signal transmission attenuation. Being backward compatible with all the previous categories, cable UTP Cat6 and cable SFTP Cat6 both can be used to support up to 10 Gigabit Ethernet speed, and operate at up to 250MHz (Cat6a at 500MHz).

What are security alarm cables used for?

Leave a comment

Security alarm cables are only some of the specialty cables we provide, but like all of our unique products, they are made to an exacting range of specifications and standards. No two cables or wires are necessarily the same, as they are engineered to deliver specific performance in their given scopes of applicability.

That makes marine battery cable very different from building wire, photovoltaic (or solar) cables, welding cables, tray cables, armored cables and everything in between.

As you become more familiar with the many different types of electrical wires and cables used in infrastructure and engineering, you’re going to come across traits and specifics that are relatively unique.

What is SFTP Cat7 – and why you don’t need it.

Leave a comment

Category 7 cable, more commonly known as a SFTP Cat7 or Cat-7 cable, is a type of high-end data transfer patch cable used in delivering the core infrastructure of wired Gigabit Ethernet setups.

It’s a shielded twisted pair cable, used principally in achieving high-speed Ethernet connections at data transfer rates of 1 Gbps or higher between directly linked servers, switches and computer networks.

Today, a highly diverse range of commercial and industrial sectors are showing increased demand for faster internet and data transfer speeds – a modern reflection of the fact that we’re continually finding ways to capitalise on the hyper-efficient capabilities of our cutting edge technology. Especially as we move ever closer to a true ‘Internet of Things’ era, where almost any device you can imagine is able to record and transmit potentially valuable user data in real-time, it’s becoming more and more important to stay ahead of an ever-steepening tech curve.

One way in which many users can aim to do just that is to buy SFTP Cat7-rated network communication cable when putting together a high-speed internet set up in the workplace or at home. As part of a coherent and comprehensive Ethernet delivery infrastructure, Category 7 cabling represents a valuable step along the path towards optimal speed and efficiency in our wired online experience.

Testing KX6 Cable Before Ethernet Over Install

Leave a comment

Testing Cable Length

All the KX6 cables that you lay within a network cabling system should already be limited to the maximum lengths that are laid out in the standards specifications. However you should still user a tester to check the electrical length of the twisted pair wires within the KX6 cables, as these are twisted together they will be physically longer than the actual length of the KX6 cable. Another reason why you check the KX6 cable length is to test for any shorts, opens or breaks in connections.

You can test the KX6 cable length by using a specially calibrated capacitive tester, but a better option is to do it with a Time Domain Reflector tester as this can also measure the distance to any faults that may show up.

Performance Testing

The above testing procedures test the physical properties of the network cabling system to make sure that everything is connected and works properly and it is also vital that you check the transmission performance of your newly installed network. This will make sure that the signal is both strong and fast enough to meet the networks performance requirements. These tests require a more sophisticated bit of kit than the testers used for basic wire mapping as they include checking the following aspects:

Attenuation – Measuring any reduction in the strength of the signal.

Cross-talk – Evaluating the KX6 cables ability to reject any electromagnetic interference.

Propagation Delay – Gauging the amount of time a signal is delayed when travelling through a wire.

Delay Skew – See the difference in propagation delay between any 2 twisted pairs in the same KX6 cable.

Does fire alarm cable have to be in conduit?

Leave a comment

Home Fire Detection System Design To be in conduit or not is the question! When installing a fire alarm system according to NFPA and NEC 90 articles, any fire alarm cable below 7 feet or in non-accessible areas must be installed in a metallic raceway.

When two hot wires touch this is called a fault?

Bare wires can inevitably touch the wrong places: Hot wire to neutral wire means a short circuit that causes sparks to fly; hot wire to grounding wire, or to grounded metal box means ground fault and possible shock.

How many types of fire alarm cables are there?

Fire alarm cables are placed into three broad categories: plenum, non-plenum, and riser. Each of these corresponds to another standardized category, and these terms reflect where the fire alarm cable can be installed safely. Plenum cable, to be used in ducts or other enclosed air spaces, is called FPLP.

Can you use 12 2 wire smoke alarm?

Either a 15-amp circuit (wired with 14-gauge wire) or a 20-amp circuit (wired with 12-gauge cable) is acceptable for powering hardwired smoke detectors. Then, a 2-wire cable is run from the power source to the first smoke detector.
