How Do I Power My Tuxedo Keypad From an Auxiliary Power Supply On a VISTA TURBO Panel?

You can power your Tuxedo Keypad from an auxiliary power supply by connecting the keypad to both the power supply and the VISTA TURBO Panel. A common negative wire will need to be run from the panel to the power supply. This wiring process applies to both a VISTA 128BPT and a VISTA 250BPT.

When power draw is not an issue, the Tuxedo Touch Keypad is normally wired to the panel. The keypad uses panel terminals 6 thru 9 on a VISTA TURBO Board. The panel will provide all the needed power to the keypad, and no additional equipment will be required. But it is important to understand that a VISTA TURBO Panel can only provide up to 750 mA of current for connected devices that draw power. The tuxedo Touch Keypad itself draws 280 mA of current, and that's just for one keypad. If you are using a few other devices with your system, then you may find that you do not have enough power for your Tuxedo Touch. In that case, adding an auxiliary power supply is your best option.

Several items are needed to power a Tuxedo Touch Keypad using an auxiliary power supply. For starters, you will need both a Tuxedo Touch Keypad and a Honeywell VISTA System. It will also require a power supply, a plug-in transformer, and a backup battery. For our example, we will be using a Honeywell AD12612 Power Supply, a Honeywell 1361 Transformer, and an UltraTech 1240 Backup Battery. As long as you do not exceed the power limit of 1.2 A for the Honeywell AD12612 Power Supply, this setup will work.

Before beginning, please consider these notes:

• You cannot share the same transformer for both the power supply and the VISTA TURBO Panel.
• If you are connecting a Tuxedo Touch using an auxiliary power supply on a VISTA Low-P Series Panel, then please check this FAQ instead.
• These same steps will also apply to other compatible touchscreen keypads, including the Honeywell Home 6290W.

Complete the following steps to add a Honeywell Tuxedo Touch Keypad to a VISTA TURBO Panel using an auxiliary power supply:

1. Power down the panel. You must always power down your panel before adding new hardware. Disconnect the backup battery, and unplug the transformer to power down the panel. There should be no LED lights on the system board, and any existing keypads should go blank once the system has powered down. The only exception is if a keypad is already using an auxiliary power supply. In that case, the keypad will display "Open CKT" (Alpha Keypad), "OC" (Fixed English Keypad), or "ECP Error" (touchscreen keypad) once the panel has successfully powered down.

2. Wire at the keypad. The Honeywell Tuxedo Touch needs a 4-wire connection. Of these four (4) wires, two (2) are for power, and two (2) are for data. We recommend using 18-4 wire for the job. However, you can always double up 2-conductor wire, or you can use a slightly thicker or thinner gauge of wire if that is what you have on-hand. Just make sure to keep track of your wires so that nothing becomes mixed up. Remember to run the wire through the Tuxedo Touch backplate before connecting so that the keypad can be properly mounted when it's time.

The chart below will assist with choosing the proper wire gauge for the distance required by your wire run. Be sure to observe the differences when using unshielded vs. shielded or wire in metal conduit:

The Tuxedo Touch has four (4) terminals for wiring. These are labeled Y, +, -, and G. Assuming you are using 4-conductor cabling, the Yellow/White wire should go to Y, the Red wire should go to +, the Black wire should go to -, and the Green wire should go to G. The connections should be nice and secure, but not overly tight. Continue to the next step once the wire has been successfully connect to the Tuxedo Touch and run through its backplate.

3. Wire the other connections. At this point you should have one end of the wire connected to the Tuxedo Touch, and the other end should still be loose. You will now take the loose end and make the necessary connections. These are listed below:

• Black Wire at Negative (-) on the Honeywell AD12612 Power Supply
• Red Wire at Positive (+) on the Honeywell AD12612 Power Supply
• Green Wire at Panel Board Terminal 8 for Data In
• Yellow/White Wire at Panel Board Terminal 9 for Data Out

You will also need to connect wires from the two (2) terminals on the Honeywell 1361 Transformer to the two (2) AC transformer terminals on the Honeywell AD12612 Power Supply. Additionally, connect a single common negative wire from Panel Board Terminal 7 to Negative (-) on the Honeywell AD12612. The UltraTech 1240 Backup Battery should be connected to the Honeywell AD12612. The 1361 Transformer can be plugged in after all the connections have been made.

We recommend following along with the diagram shown below:

4. Test the keypad. Power your VISTA TURBO System back on by plugging in the transformer and then reconnecting its backup battery. Remember that the panel and the power supply cannot share the same transformer. If everything was set up correctly, then the Tuxedo Touch Keypad should also power on with the system. Also keep in mind that you will need to address the keypad with the VISTA TURBO System.
