The Honeywell 5800MINI is a single zone, slim wireless door or window contact that will replace the popular 5811. This is the newest release of the 5800 series line of sensors. It is also the first contact manufactured by Honeywell to be equipped with a status LED! The rounded edges give the sensor a more aesthetically pleasing look and allow it to blend into the door or window a bit better. The 5800MINI also uses a 3V lithium coin cell battery (i.e. Panasonic CR2032) and is designed to last three to five years on a single battery. The maximum range back to the panel is 200 nominal feet. This means in open air it is capable of traveling 200 feet back to a compatible 5800 series RF receiver. Both battery life and wireless range are much improved on this sensor in comparison to the 5811. It also tamper proof and supervised like all other 5800 series contacts.

The super slim dimensions of the 5811 (2 1/8 inches high by 1 3/16 inches wide x 1/4 inch deep) were touted as the slimmest sensor on the market when it first released. However the slim depth is more aesthetic than functional. Reacting to customer and installer feedback Honeywell decided to shrink the width of the 5800MINI to 1 inch and keeping the height and depth the same (2.2 inches high by 1 inch wide by 0.25 inches deep). This dropped the width by 3/16 of an inch. This may not seem like a lot but what this does is allow installers to mount these sensors on double hung windows that may have a smaller space to work with. It may not matter as much when installing the contact on a door but window protection can be very tricky with surface mount contacts. Often times it is the matter of an 1/8 or 1/4 inch that prevents the use of a specific sensor.

When programming the 5800MINI you can auto-enroll by placing the panel into learning mode and tripping the sensor or you can manually map in the unique seven digit serial number. When you auto-enroll it should automatically select loop 1 as the proper loop. If you learn it in by popping the tamper cover and not faulting the sensor it will select loop 4. You always want this product on loop1! There are no internal screws for a wired loop like that of a 5816 sensor. Just an internal reed switch that interacts with a local magnet. The magnet is included and there is an increased maximum magnet spacing gap of 1 inch. The 5811 only supports up to .75 inches. This can leave you more flexible with older doors or windows that in the closed position may have a slight opening.

The newly featured LED has three colors: Blue, Green and Red. The blue and green LEDs are active for the first 15 minutes after the battery is installed or the tamper cover is removed. The blue LED illuminates when the magnet is within the 1 inch specification. Basically this is confirming proper installation of the magnet in relation to the reed switch. The green will flash each and every time the 5800MINI transmits a signal. The red LED is active for 2 minutes after any transmission (a fault or trouble signal from the sensor). The red light will flash once every five seconds when there is a low battery. When the 3V battery reaches 2.3V that will initiate a low battery alert to the panel on the next transmission. At 2V the sensor will be completely dead.


Yes the 5800MINI is compatible with the 6160RF receiver. Happy to hear that you are finding our site useful!
Hi, Love this site. A lot of useful info. I am planning on adding some sensors to my Vista 20 system with a 6160RF keypad and had a question. Will the 5800MINI sensors be compatible with my setup? Thanks.
Definitely going to be adding a few of these. Thanks for the write up!
Yes, the 943WG-M ( ) is a standalone magnet you could use to provide two places that will keep the sensor/zone "happy".
Is there a way to purchase just additional magnets for this sensor to create a two stage window setting, (closed window and partially opened window, but still be armed while partially opened)?
