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
You may have inherited a Radionics security system when you bought your house, and are wondering if it can be used or not.
If the system doesn’t have power, check to see that the low voltage transformer is plugged in and the main panel battery is connected. If the system hasn’t been in use for a while, it may need a new battery. If so, see this page on DIY alarm system battery replacement.
If your keypads are beeping, the system may have a "trouble" condition. Learn what to do at Radionics Security Systems-How to Stop Beeping Keypads.
If you need a user manual, see this page on Radionics Alarm Manual Sources.
If you don’t have a working arm/disarm code for the system, skip down this page to my suggestions for Existing Radionics Systems.
If you do have a working code for the system and want to know how to use it, read on.
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.
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, your choices are limited. Why?
Radionics alarm systems are proprietary, or 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 Radionics home security systems on eBay and elsewhere.
For programming anything other than basic code changes, you’ll need either a special programmer or help from a Radionics authorized alarm company.
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.
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.
