Radionics Home Security

Keypad Commands for Newer Systems

For many years, Radionics home security systems used a set of standard “Commands” to perform arming, disarming, and many other functions of the system. Sometime in the 1990’s, Radionics Inc. strayed from this convention, and designed panels using a new set of numbered commands.

Radionics Home Security - D223 Keypad with Clear Key for Use with D2212 Systems

This page provides help with newer Radionics home security systems, like the D2212 and other D2000-series panels using D223 or 222A keypads. These keypads have a “Clear” button, but no “Command” key.

Note: The steps listed on this page will only work with newer Radionics Systems. 

If you have an older-version Radionics alarm system, your keypads will have a dedicated “Command” bar or “CMD” button. 

These systems included the D6112, D8112, D7212, and others, using keypads like the D620 and D1252. 

For help using these systems, see my page on Radionics Security System Keypad Commands for Older Systems

Your particular system may not follow all of these functions exactly as described, since most panels have undergone several revisions. I recommend you get a copy of the User Manual for both your keypad, as well as for your main control panel. Between these manuals, you’ll have all the details on how to use each specific function.

For help finding a Radionics manual, see my page on Radionics Alarm Manual Sources.

Keypad Commands for Newer Radionics Alarm Systems

Press 1 - Perform System Test

Requires Owner Code to authorize. Pressing 1, followed by an Owner Code, tests the bell, battery, and telephone line, in that order. The testing can take up to 15 minutes total for all three tests. At the conclusion of each test, the results are displayed as either “Passed” or “Failed”.

Press 2 - Enter Remote Programming Mode

This function is used to allow the system to accept programming changes from an alarm technician in another location, via its telephone line connection. You’ll only use this when instructed to do so by your alarm company.

Press 3 - Reset Sensors

Radionics home security systems use this function to reset smoke detectors after they have been triggered. To use the function, press “3”, followed by your Owner Code. The keypad will display “Resetting…” for up to 20 seconds. This resets the system, and momentarily removes power to connected smoke detectors (or glassbreak detectors, if present.)

Press 4 - View Alarm Memory

After pressing the 4 key, press and hold the 6 key. The system will display the point or points that caused the last alarm. After all points have been displayed, the system will prompt you to clear the alarm memory by tuning the system on.

Press 5 - Change Passcodes

This feature allows a user to change their own User-type passcode, and doesn’t require an Owner-type code.

  1. Make sure the system is disarmed/off.
  2. Press the 5 key. The OK tone sounds and the display prompts you to “Enter Old Code”.
  3. Enter your current passcode.
  4. Display prompts you to “Enter New Code”.
  5. Enter a new code (must have same number of digits as old code.)
  6. Display will prompt: “Enter New Again”.
  7. Re-enter the new code.
  8. Display will show “Code Changed”.

Press 6 - Show Users

Pressing “6”, by itself, will display a list of the codes in the system by user number, followed by the code-type (Owner or User) of each one.

With a valid Owner Code, the 6 command can also used to change user passcodes and types.

See the Owner or User Manual for your specific system for details.

Press 7 - Select Watch Tone

The Radionics home security "Watch Tone" function allows the system to sound a tone when a door or window is opened while the system is disarmed. Many use this feature as a “door chime” for their home or business.

To set the watch tone, press the 7 key. The keypad will display the current watch tone selected. To change the tone, enter your owner code.

The system will scroll through the watch tone options. Choose the setting you want by pressing the indicated digit:

  1. Off: The faulted point will show on the display, but no tone will sound.

  2. Short Beep: Probably the most commonly used option, this displays the point name and sounds a brief tone when a point is faulted.

  3. Beep til Key: Displays point name, and sounds a repeating tone until the Clear key is pressed. Probably the most annoying option possible.

  4. Beep til Closed: Displays the point text, and sounds a repeating tone until the door or window is closed. On second thought, THIS may be the most annoying option possible!

After choosing the tone you want, the system confirms your selection, then returns to the idle display.

Press 8 - Select Watch Points

Here you choose which points you want to “watch” when the watch tone function is turned on. This will usually include entry doors, allowing you to know when one one goes in or out. It typically will NOT include interior protection such as motion detectors, since they would trigger beeping almost constantly as you move around the area.

To select your watch points, press 8 and enter your passcode. The display will show which points are are currently being watched (Watch On), and which ones aren’t (Watch Off). This is followed by prompts to change the current settings.

Follow the instructions by pressing the desired point number, followed by the * key, to change watch points as you would like them. After each change, the display will confirm the new watch point setting.

When finished, press the Clear key to return to the idle display.

Arming Your Radionics Home Security System

First, check to see that the keypad is showing “System OK”, indicating all points are ready to arm. If the display shows “Not Ready to Turn On”, press and hold the * key to view the faulted points. Secure these points until the display does show the System OK message.

Press 9 - Turn System All On

Pressing the 9 key once will arm the system All On (perimeter and interior protection activated.) Exit and entry delays will be in effect.

Pressing the 9 key twice will arm the system All On, but without entry or exit delays.

Press 0 - Turn System Part On

Pressing the 0 key once will start exit delay. At the end of the exit delay, the system will be armed PartOn, with entry delay in effect.

Pressing the 0 key twice will arm the system Part On, but without entry or exit delays. Use this setting when staying home, and no one else is returning.

To turn the system off, enter your personal passcode.

Press Clear - Exit any function / Silence trouble tone

Your Radionics home security system may have other functions available, depending on the particular model. For details on the operation of your system, always check the model-specific User Manual.
