How Do I Add Additional Keypads on a Honeywell L5100?

You can add additional keypads on a Honeywell L5100 by configuring the settings of the keypad to match the settings of the panel. The Honeywell L5100 is part of the Honeywell LYNX Touch Series of wireless AIO systems. It can support Honeywell 5828 and Honeywell 5828V Wireless Keypads.

Complete the following steps to pair a 5828 or 5828V Keypad with a Honeywell L5100:

1. Set panel House ID. Begin from the home screen of the Honeywell L5100. Select Security > More > Tools > Installer Code (default is 4112) > Program > System Type > RF House Code. From that screen, you can set the panel House ID. The values from 01 to 31 are available. The default selection is "10". You will later apply this setting to the keypad, so make sure to remember it. Once you have made the selection, press "Done" in the lower-right corner of the screen. Next, press the "Save" button in the lower right corner. Then press the return arrow in the upper-right corner. Make sure to select "Yes" when asked if you want to allow the Installer to reenter programming. Finally, press the return arrow in the upper-right corner again to return to the main screen.

2. Set keypad House ID. From here on out, all steps will be completed from the 5828 or 5828V Keypad. If your keypad is running strictly on battery power, it must be activated before it can be used. This can be done by pressing and holding the [*] key for a few seconds. The keypad will light up and produce some type of sound to show that it has been activated. Activating the keypad with the [*] key is not necessary if the keypad is running on AC power. Once the keypad is active, press and hold both the [1] and [3] keys simultaneously. Wait until the keypad starts flashing between "00" and "--". This indicates that the programming mode for the keypad has been accessed. We will only be discussing the steps for programming the keypad to the Honeywell LYNX Touch L5100 here. If you would like to see additional keypad programming options, please check the Honeywell 5828 and 5828V Install Guide.

Next, press [1] to access the House ID sub-field. You will know you accessed this field because the keypad will flash between "t1" and the current two-digit House ID setting. Enter the same two-digit House ID value you set to the L5100 System in Step 1. Once you have done this, press the [*] key to continue. The keypad will go back to flashing between "00" and "--". This will confirm that the keypad House ID has been set.

3. Set the System Type. Press [2]. This will have the keypad access its System Type sub-field. At this time, the keypad will flash between "t2" and its current System Type value. Sine the L5100 is a LYNX Touch Panel, you will press [2]. If you were configuring the 5828 or 5828V for a Honeywell VISTA System, you would enter [1] instead. Once you have entered [2], press the [*] to continue. The keypad will go back to flashing "00" and "--". You can then exit programming by pressing the [*] key.

4. Test the keypad. Make sure the keypad is active. Enter the command [Master Code] + [3]. The Master Code is the same code that you use on the L5100 for general arming and disarming. It is set to 1234 by default, but it is typically changed by the end user. After entering in the command, the keypad should indicate that the system is entering its arm stay mode. This can be confirmed by checking the L5100. To disarm the system, enter [Master Code] + [1] on the keypad. Both the keypad and the panel should display that the system is disarmed. Being able to arm and disarm the system from the keypad indicates that it was programmed successfully.
