There’s no time like the present!

And when it comes to Emergency Preparedness, you can never start planning too soon. Luckily, a solid plan doesn’t have to be complicated to be effective. See our post Emergency Preparedness and Two Way Radios

When it comes to emergency planning in a business environment, it is important to understand that the two-way radio system is the heart of a building’s communications system. In most commercial buildings, management, engineering, and security staff all communicate with each other on hand-held radios operating on a radio infrastructure within the building. Most radio systems consist of a distributed antenna system connected to a radio repeater that operates off of the building’s electrical power.

In an emergency situation, it is very important that the radio system stays up and running even when the building power shuts off. This is why every building (even those with E-Power systems) should have an independent dedicated battery back-up system in place to be fully-prepared for a power outage.

Battery Back-Up Systems (BBS) come in different configurations. Each BBS is designed to meet the specifications of the radio system it will support.

A Standard BBS consists of several components:

  • 100 amp hour AGM Batteries
  • Battery Enclosure
  • 3- Stage Battery Charger
  • Harness (Cabling & Connectors)

Emergency Plans

Emergencies create anxiety and panic. An Emergency Plan reduces anxiety and panic by providing structure. It helps keep everyone on the same page and brings order to the chaos.  

This is why it is so important to have a well designed Emergency Plan in place before the next emergency strikes. A good emergency communications plan clearly defines who does what, where, and when. It also defines what radios will be used and how to use them during an emergency.

SJM Industrial Radio can help you choose the right radios and Emergency Radio Kits based on the size and scope of your business.Contact us today to schedule a no-obligation phone consultation.

What is the battery recycling process?


According to the Environmental Protection Agency (EPA), each year Americans throw away more than three billion batteries. That's about 180,000 tons of batteries every year! Batteries are a combination of the outer plastic, metal components and the inner chemical elements. Plastic items can take up to 1,000 years to decompose in a landfill; chemical elements can take millions of years to erode. This is why it is important to have a plan for recycling your depleted batteries at the office and at home.

At some point in every WWII movie there is a dramatic scene where a soldier gets pinned down by gunfire, grabs his two-way radio and makes a plea for help before it’s too late.  Although this may be a corny example, it does illustrate that two-way radio has been the first choice for instant communication by mission-critical organizations for quite some time. 

Although military personnel have used radio communication ever since it was introduced back in the 1940's, Community Emergency Operations and thousands of businesses soon followed, making two-way radio the "go-to" choice for anyone seeking a robust communication system for over 60 years.

In fact, two-way radio is considered mission-critical for business and public safety officials, now more than ever. One reason is that two-way radio has high-operational efficiency in emergency situations, whereas other communication systems, like cell phone networks, often become overloaded leaving users unable to connect.

Another reason why two-way radio is so popular is that it provides the ability to easily connect instantly to one person for a private conversation, or to many people simultaneously for a group conversation without having to go through awkward set up commands and operations.

What is the difference between THE CP200D Analog and the CP200D Digital TWO-WAY RADIO?


The CP200D radio is the latest incarnation of one of the most popular Motorola two-way radios ever produced. Evolving from the popular P series of analog radios in the 1990s, the CP200D does something that its predecessors could never do – it operates in both analog and digital modes- often referred to as “dual mode.”

This is important because the dual-mode feature allows a fleet manager to easily incorporate CP200D radios into an existing analog radio system without having to change anything in the current operation.

Once the older analog radios are replaced with the newer “dual-mode” radios, the fleet can be switched to a full-digital operation with simple reprogramming. Moving a fleet to full-digital operation allows a company to gain the many benefits that digital technology provides over the older analog technology.

See is it time to migrate to digital? Analog vs Digital Two Way Radio 

Although there are several benefits in upgrading to a digital two-way radio system, some people believe they will remain on an analog system for many years. To accommodate this sector of the market, Motorola offers the CP200D in an “Analog Only” configuration.

This configuration costs slightly less than the dual-mode version because it does not include the software upgrade that allows for digital operation.  To upgrade the Analog Only radio for digital operation, a software upgrade must be purchased and installed into the radio.

It is important to note that purchasing an Analog Only radio and adding a digital software upgrade separately is actually more expensive than purchasing a dual-mode CP200d model that is already digitally capable and requires no additional software upgrade.

For people who believe they will never go digital, the CP200D “Analog Only” costs less money and works great as an analog radio. For people who see the benefit of a digital system, the already enabled CP200D Digital or dual-mode radio is a better choice. See our CP200D Product Page for spec sheets and brochures.

In Part Three of this series on Digital Migration, we cover Voice and Data. 

Part Three: Voice and Data  

Today's digital two way radios have enhanced voice and data capabilities that give radio users the ability to run productivity-enhancing applications directly from their hand held radios. Current applications include messaging, location based services, bar code reading, and form applications. And according to radio manufacturer information the growth potential for new application development looks very promising as third-party developers report interest in developing more applications for the industry.

Because of these new data capabilities, the term "Smart Radio" has been coined to refer to the latest release of digital radios. In reality, the name is sort of misleading because typical smartphone activities like surfing the web, sending video/images and synchronizing with remote office desktops are not available on the radios due to the large bandwidth required by the applications.

For many business managers, this is actually a blessing in disguise because they can control the type of the application workers access on their device during the workday (Think, no work time lost on facebook, snapchat, etc...) and more importantly digital radios have no monthly fees.

In Part Two of this series on Digital Migration, we discuss Better Capacity.

Part Two: Better Capacity

Regulatory pressures and real-world needs are driving a demand to expand the capacity of the business designated slice of the RF spectrum by leveraging new technology. As it happens, digital two way radio technology is very bandwidth efficient and actually allows two separate "channels" to operate on a single 12.5 kHz frequency, effectively doubling its capacity. (See chart below)

In addition to making efficient use of the RF spectrum, this feature helps minimize licensing costs associated with operational expansion because the additional channels do not require additional frequencies. For a fast growing business that is expanding its radio operations this can mean significant savings while expanding communcations. 

In the following excerpt from TDMA TECHNOLOGY, a whitepaper published by Motorola Solutions, the details are explained.
