The Honeywell 4142BLK is the removable terminal block found on Honeywell Polling Loop Panels, such as a Honeywell VISTA-128BPT, VISTA-250BPT, VISTA-50P, and many more. You connect devices such as keypads and wired sensors to the 4142BLK so that they can be used with the alarm system.
Installing the Honeywell 4142BLK is very easy. You just slide it over the designated pins on the panel. From there, you can start connecting devices for use with your system. Almost all devices that wire-in with the system will connect with the Honeywell 4142BLK. This includes hardwired sensors, keypads, communicators, and more. Each Honeywell 4142BLK comes with three (3) sets of terminal blocks, with ten (10) terminals in each block. That is thirty (30) terminals in total.
Since the layout of the panel pins has to match the layout of the terminals on the 4142BLK, you can only use the unit with Honeywell Alarm Panels that have the protruding pin at the top of each terminal. Only the Honeywell Poling Loop Panels have this feature, so you can only use the Honeywell 4142BLK with those panels.

What's great about the Honeywell 4142BLK is that if you ever need to replace your alarm panel, you can keep all devices connected with the 4142BLK, pull the 4142BLK off from the panel, and bring it and all the connected devices to a new panel. That way, you have basically swapped systems without having to individually rewire each and every panel terminal. This can save you quite a bit of time if you are putting in a replacement panel of the same type.
