Radionics Alarm Systems

Getting the Most from an Existing System

Radionics alarm systems have been installed in homes and businesses for decades. Their panels began with the early Omegalarm 4012/8012 basic systems with just a few zones and user codes. In the last 30 years, expandable systems have advanced to handle 100 zones or more, with about as many user codes available.

Radionics Inc is now a part of Bosch Security Systems, an international company offering many intrusion alarm, video, fire, and access control products.

You may have inherited a Radionics security system when you bought your house, and are wondering if it can be used or not.

If so, here's what to do:

Radionics Alarm Systems User Manuals

If you don’t already have manuals for the system, download free copies of the User Guides for your main panel and keypads from

Many Radionics alarm systems used several different keypads with each model of main panel, and Radionics published manuals for all of them. To use the system at its full potential, it’s helpful to get a copy of the Radionics alarm manual for both the panel and the keypad(s).

Radionics main panels use a 4-digit model number, such as 8112, 9412, etc. These all technically begin with “D”, as in “D4112”. “D” stands for “device”, and it is often omitted in references to equipment. Some of the most popular models are/were:


(As far as I know, all of the panels listed above are out of production, with the possible exception of the D7412 and D9412.)

You can find the panel model number on the main control board inside the alarm box that contains the back-up battery.

Radionics keypads use 3- or 4-digit model numbers, again often omitting the D-prefix. Some common keypads include these models:


Keypad model numbers are found on the back of each unit, so removing the keypad from the wall is the fastest way to find the model information.

If you don’t want to remove a keypad, you can do a Google image search for your control panel model number, followed by the term "keypad". This will bring up images you can compare to your own keypad(s), leading you to its model number.

Existing Radionics Systems

As mentioned above, it’s not uncommon to find a Radionics alarm system already installed in a house you purchase. In many cases, the alarm can be used if it’s in working order and at least one arm/disarm code is known.

If you have a working code, you can just download the security system manuals you need as described above, and use the system as you like.

Without a working code, you are limited.


Radionics alarm systems are proprietary, and sold exclusively through the manufacturer. This means that originally, the only way to purchase Radionics  systems was through Radionics authorized dealers. These days, you can purchase used Radionics home security systems on eBay and elsewhere. 

I don't recommend doing this, and here's why:

For programming anything other than basic code changes, you’ll need either a special programmer or help from a Radionics authorized alarm company.

Just for fun, I searched for the programmers needed for Radionics panels. I found the Radionics D5000 Omegalarm Programmer (used on the older 4012/8012 panel) for about $100.

The Radionics D5200 Programmer (used on later panels) was for sale for about $450.

In addition to needing a special programmer, some Radionics systems are “data-locked”. Datalock is a feature that enables only the company that originally installed a system to program it.

Using the handheld programmer is the only way to change the program settings on most Radionics panels. The cost of the programmer and the steep “learning curve” to use it make it impractical for the average homeowner.

Unlike some other brands of alarm such as Ademco, DSC, and Moose, there is no way to “factory default” a Radionics panel to gain access to programming mode.

Radionics Alarm Systems with No Known Code and/or Data Locked Systems

At least one valid arm/disarm code is needed to use a Radionics system (Or any other system, for that matter!)

Without a valid code, your only options are limited to calling in a Radionics alarm dealer, or replacing the system.

Find an authorized dealer using the Bosch Security US Dealer Locator.

If you don’t have a brand preference, and you have a hardwired system, the Radionics equipment can be replaced with almost any brand of alarm you might choose.

The panel and keypads are the key elements that must be replaced. The door and window contacts, motion sensors, and often even the low-voltage smoke detectors are basically generic, and can be used with any brand of alarm system.

Do you have an older system that's starting to have problems?

Or, do you have a working system, but no programming information?
