Honeywell Home PROSIXMINI Posts

One of the more interesting things about the Honeywell Home PROSIX Sensor lineup is that it features two (2) different "mini" door and window sensors. These are the Honeywell Home PROSIXMINI and the Honeywell Home PROSIXMINI2. Today, we will be comparing and contrasting these sensors.


When the Honeywell Home PROA7PLUS Alarm Panel first hit the market, a new lineup of sensors also made their debut. These are the Honeywell Home PROSIX Sensors, and they make the perfect complement to Resideo's latest security system. These devices are best-known for their 128-bit AES encryption and their improved wireless range over the Honeywell and Resideo Sensors that came before them. The PROSIX Sensors can only be used with the PROA7PLUS, and until Resideo makes local programming available for the system, you will need the help of your monitoring company to enroll any new sensor.

At first glance, the PROSIX Sensor Family seems pretty straightforward. It is a very robust lineup, featuring everything from security sensors like motion detectors and glassbreak listeners, to environmental sensors like flood sensors and temperature sensors. But there is one anomaly that often makes people turn heads. That is the presence of two (2) different "mini" door and window contact sensors, the PROSIXMINI and the PROSIXMINI2. Both are surface-mounted contact sensors, and both monitor an interior door or window for opening and closing. A third sensor in the lineup, the PROSIXCT also accomplishes the same task, but that sensor is considerably larger and features an auxiliary input to provide wireless transmitter functionality. But it begs the question - why is there both a PROSIXMINI and a PROSIXMINI2?

Starting with the PROSIXMINI, this sensor actually looks virtually identical to the Honeywell SiXMINICT from the Honeywell SiX Series Lineup made popular by the Lyric Controller. It's likely that Resideo took the same plastic casing from the SiXMINICT and repurposed it for the PROSIXMINI. And when compared the alternative option from the same sensor generation, the PROSIXMINI2, the only category where the PROSIXMINI "wins" is in size. The PROSIXMINI (2.44"L x 1.25"W x 0.45"D) is the smaller and more discrete sensor when compared with the larger and slightly bulkier PROSIXMINI2 (2.9"L x 1.15"W x 0.75"D). The reason why the PROSIXMINI is able to maintain a smaller profile and relatively "flat" design is thanks to its use of a CR2450 coin battery. Meanwhile, the PROSIXMINI2 uses a CR2 battery, which has a more traditional, cylindrical shape,

But before you go declaring the PROSIXMINI to be the winner, you might to consider the fact that the PROSIXMINI2 outshines its smaller and flatter competitor in virtually every other possible aspect. The PROSIXMINI2 has a wireless range of 500+ feet in open air, while the PROSIXIMINI is limited to 200+ feet. The PROSIXMINI2 also wins in the battle of battery life, as its lithium CR2 battery should last about seven (7) years before a replacement is needed. The lithium CR2450 battery inside the PROSIXMINI can only be counted on for about five (5) years. Also, some equipment testing has shown that the use of coin cell batteries inside a sensor can be problematic. It's likely that Resideo wanted to give users an alternative option that uses a more trustworthy battery.


Now, you're likely wondering, which sensor should you get? The PROSIXMINI or the PROSIXMINI2? If aesthetics are the single most important concern to you, and you simply want the smallest and most discreet sensor, the you can make a case for the PROSIXMINI. But if you ask us, we think the PROSIXMINI2 is the superior option, because of its improved signal range, extended battery life, and more reliable battery performance in general. But rest assured, both the PROSIXMINI and the PROSIXMINI2 should work very well on any PROA7PLUS Security System.
