This is the Honeywell Hardwired Alpha Keypad that can be used for programming. They also call it the Custom Alpha Keypad. Additionally, it's compatible with all Vista Panels. It's also recommended that everyone that owns a Honeywell Vista Panel has one of these so they can be serviced and troubleshot easier.  This keypad is also nice to have because if a door is open, it will give you the zone number and the name of the zone on the screen.

The Honeywell Tuxedo Touch Keypad with Wifi is the hardwired keypad you would want if you wanted to add automation features to your Honeywell alarm panel.  (Or you could add the Vista Automation Module and the New Color Touchscreen Keypad instead or just add the LTE Module and use a standard Alpha Keypad. It's a talking color touchscreen keypad with integrated WIFI capability. It can be used with Total Connect but it is not compatible with ADT Pulse or ADT Command or It can be used to control your security system, for home automation, for remote access, and it can even display camera video from the Honeywell Total Connect Wifi Cameras. Additionally, it's compatible with almost any Vista control panel that is a 15p, 20p, or 21ip. The Tuxedo Touch can be used alone as a home automation controller without any security system. However, most people use it along with their Vista security system. Additionally, you can control it remotely using Total Connect 2.0, or you can connect directly to the keypad via port forwarding on your router.

This is the Replacement Transformer Honeywell Lynx, Quickconnect, Simon XT Panels that does not include a ground anymore (I guess it was not really necessary). It is also the same transformer that works with the Simon XT. It is 9VAC with 25VA power rating. So the one you will get will not have a ground, just the two screw terminals. (They do not make the one with the ground anymore)

This is the Alpha Custom Programming Hardwired Keypad for Honeywell Vista or Safewatch Pro Systems. It's more advanced than the numeric keypad because it has two lines of letter or number characters. This is why it's usually needed to program the alarm system. It also helps to know which zone is tripped by giving a word and number description of the zone instead of just a number. It has four wires that provide power and data. It's also very easy to install, replace, or add additional keypads to the panel.

The ADT Wireless Smoke Detector is a detector that's compatible with Safewatch Pro 3000, Quickconnect Panels, and now TS Panels.

By adding this detector to your home, help can be notified automatically in the event of a fire.
