Alarm Grid now offers the Altronix SMP3 auxiliary power supply which works great when adding multiple Tuxedo Touch or Tuxedo Touch WIFI keypads to a Honeywell VISTA Series alarm control panel. A Honeywell VISTA-20P alarm control panel has 600mA of auxiliary power supply. Each Tuxedo Touch draws up to 310mA and each Tuxedo Touch WIFI draws up to 350mA. Also, any alarm keypad, wireless receiver or AlarmNet alarm monitoring communicator connected to your VISTA-20P will also need power from the available 600mA auxiliary. That means that there is very little power left over for your Tuxedo Touch keypads. While the Honeywell AD12612 is an auxiliary power supply with 1.2A of power output, you will need a larger power supply like the SMP3 which puts out 2.5A if you have lots of devices drawing power or you have multiple Tuxedo Touch keypads.
Here at Alarm Grid, we recommend connecting all of your Tuxedo Touch and Tuxedo Touch WIFI keypads to an SMP3 power supply to make your alarm installation as easy as possible. You will need to hook up a Honeywell 1361 AC transformer to your SMP3 and you should also connect an Ultratech 1240 backup battery so that your Tuxedo Touch keypads will work even during a power outage. With a VISTA-20P alarm control panel, you should be able to fit the SMP3 and the extra backup battery inside the same alarm cabinet that houses the VISTA-20P. Powering your Tuxedo Touch keypads is easy with an SMP3 auxiliary power supply.
