Honeywell 5800MINI vs Honeywell 5820L

The 5800MINI and the 5820L are two different door and window contacts. They are both wireless sensors that operate at a frequency of 345 MHz. This makes them compatible with the same alarm systems. However, their shapes and profiles are different, with the 5820L being longer and skinnier.


The 5800MINI and the 5820L have many similarities. Both are manufactured by Honeywell, and both send uni-directional wireless signals at a frequency of 345 MHz. This makes both devices compatible with any Honeywell Lyric Controller, Lynx Touch Panel and VISTA System with an added wireless receiver. They can also be used with the GC3 and GC2 panels from 2GIG.

The two devices also operate in the same manner. They consist of a sensor and a magnet. The sensor is mounted on the frame of the door or window, and the magnet is mounted on the door or window itself within about half an inch of the sensor. When the door or window is opened, the magnet will separate from the sensor. This will cause an internal reed switch inside the sensor to activate. When this happens, the sensor will send a signal to the alarm system to let it know that the door or window has been opened. The system will then perform the programmed Response Type for the wireless zone.

However, there are some differences between the two sensors. The most obvious is their dimensions. The 5820L is taller and skinnier, while the 5800MINI is shorter and wider. The 5820L is also a little thicker than the 5800MINI. As for their actual dimensions, the 5820L measures at 3"H x 0.5"W x 0.8"D, while the 5800MINI measures 2.2"H x 1.0"W x 0.25"D. However, both of the sensors are quite small for surface-mount contacts.

But due to the skinnier profile of the 5820L, it does not have as far of a range as the 5800MINI. The 5820L can operate at a maximum distance of 150 feet away from the panel, while the 5800MINI can communicate from up to 200 feet away. Keep in mind that obstructions may reduce these ranges.

Another minor difference between the two devices are the batteries that they use. The 5820L uses one AAA lithium battery, while the 5800MINI uses a CR2032 lithium coin battery. Both sensors will require a battery replacement roughly every three to five years. Finally, the 5800MINI includes an LED light for ensuring proper sensor-magnet alignment during setup, while the 5820L does not have any LED.
