Beacon Light Monitoring: Automatic Monitoring Vs. Hiring 24 Hour Staff

When a light beacon at the top of a communications tower goes out, the Federal Aviation Administration (FAA) must be notified immediately and the beacon repaired swiftly or hefty penalties will have to be paid.

Also, with the beacon light out, your tower becomes a hazard to low flying aircraft. Therefore, tower lights must be monitored. Lack of monitoring can potentially cost tens of thousands of dollars in fines if outages go unreported, or even greater losses if an accident were to occur.

Monitoring your beacon lights is mandatory, but there are two different ways you can go about it: deploying a remote monitoring system or hiring 24 hour staff.

As an experienced provider of network remote monitoring, we - at DPS - have been helping many clients through the last 30 years, and we know that remote monitoring can give you confidence that your revenue-generating equipment is operational and online.

However, we also recognize that sometimes remote monitoring devices might not be the best option for you. Independently of what choice is better for your scenario, you need to make sure you're making a conscious choice.

So, before making up your mind, learn the pros and cons of automatic indication and hiring 24 hour personnel.


Rules/Laws for Beacon Lights Monitoring

The Federal Communications Commission (FCC) has several rules for antenna structures to ensure aircraft safety. Some of these rules are:

Not abiding to these rules will result in heavy fines and liabilities upon the tower owner.


Automatic Remote Monitoring

No matter the size of your network or how many sites you may have, remote monitoring starts with a Remote Telemetry Unit (RTU) deployed at each of your remote sites. The RTU's job is to monitor your beacon lights, as well as anything else you need - such as temperature, doors, motion sensors, humidity, and critical equipment alarms.

Your RTU should be able to send you instant notifications via email, text message, or voice messages. This is very important because you need to notify immediately the FAA if your beacon lights go out, and take immediate action to turn these lights back on.

Pros

There a number of advantages of having a remote monitoring system. Some of these are:

1. Continuous Watch No Matter Where You Are

The fact that you can be able to access your beacon lights status from practically any place makes it easier for you.

This means that you don't need to be at your tower site - you don't even need to be at your work place for the most part - to check the status of your lights and any other equipment that you're monitoring.

This is especially useful for situations with harsh or dangerous environmental conditions, or where a single technician or team must visually monitor multiple beacon lights located at multiple tower sites.

For most remote monitoring systems, all you need to have is a computer and internet to be able to access your system's interface, and you'll be good to go.

2. Remote Control

The RTU on your remote monitoring system collects a lot of data with its discrete, analog, and other specialized inputs, and that helps to build your situational awareness of your beacon lights that might be hundreds or thousands of miles away. Based on this data, you'll realize that you need to take action.

Imagine that you have a commercial power failure at your tower site - affecting your beacon lights. You're remotely watching your backup battery levels drop, and - at a certain point - it's time to turn on the generator.

Most RTUs nowadays have control relays outputs. With them, you're able to remotely activate just about any piece of equipment.

In our generator example, you're able to turn on that generator without even getting up from your desk. You'd be saving time, labor expense, fuel, and truck wear and tear.

Another benefit of having remote control equipment is that, with a RTU smart enough to take action, you don't have to manually operate a control relay.

You'll find different trade names for the technology, Derived Controls for example, but what matters is that you can pre-program rules for each control relay. Whenever the conditions you specified are met, your RTU will automatically activate (also referred as "latch") that control relay.

Going back to our generator example, you wouldn't be required to use the RTU interface at all. Commercial power would fail, your batteries would gradually drain, and - when your remaining batteries hit a pre-programmed low threshold (20% for example) - your RTU would latch the relay and turn on the generator to keep your beacon lights on. You'd still get a notification of each alarm condition and the relay activation, but your RTU won't allow the site to go dark if you aren't paying attention.

3. High-Quality Monitoring Pays for Itself

By having a remote monitoring and control system, you'll be able to remotely connect to all of your gear - not only your beacon lights - right from your desk. Instead of paying your technicians to jump in a truck and waste time, fuel, and money, you can have them remotely access your equipment quickly from the central office, them move on other projects.


Windshield time is one of the hidden expenses of operating remote sites, and it will nibble away at your company's profitability. "Windshield time" is all the unproductive time that your technicians spend in the car traveling to and from remote sites.

Also, another point to keep in mind is that by preventing a single outage at your tower sites, your monitoring equipment is already paying for itself.

4. Don't Need Time Off

An efficient remote monitoring system is a tireless protector of your network. It doesn't take time off, it doesn't go on vacation, or call in sick. It works 24x7x365.

Cons

On the other side of the coin, there are disadvantages as well. Some of these are:

1. It Always Has to Be Connected to a Network

In the event that your network goes down for some reason, such as power failure, you won't be able to access the status of your monitored equipment.

This is specially challenging because you'll lose visibility over your beacon lights, and won't be able to know if they are working properly or not. If this were to occur you may need to send personnel to the site to visually monitor your beacon lights.

2. Security Threats

Using a remote monitoring system can bring you some security threats, such as hacking. If malicious people are able to crack the code and hack into your system, they can steal vital information as well as take control of your remote site through control relays.

Therefore, you need to keep that in mind and make sure your system has reliable security features to deal with these kinds of threats.


24-Hour Staff

Apart from having a remote monitoring and control system, you can keep an eye on your beacon lights by simply sending people physically to your tower sites to make sure your lights are on and everything is working as its supposed to.

Pros

1. You Might Avoid Additional Costs

When you have techs responsible for visually monitoring your beacon lights, you don't have to worry about some costs that comes with a remote monitoring system. Some of this costs are:
