Good, But Discontinued!

The Honeywell 5816MN is a miniature version of a Honeywell 5816 Door and Window Contact Sensor. It retains all of the useful features of the regular 5816, but it is in a more compact size that end users are sure to appreciate. But the sensor has been discontinued, so you will be hard-pressed to find it new. However, Alarm Grid still recommends this sensor if you happen to find a used model somewhere. It will serve you well whenever you open or close your door or window. Therefore, we reward the Honeywell 5800MN with a 5 Star rating, which is the best rating we can give a product.

There is so much to like about the Honeywell 5800MN. It is very small and compact, which will prevent house guests from remarking, "Hey, what is that on your door or window?" It has two (2) programmable loops. The first loop, also known as Loop 1, allows you to connect an external hardwired contact sensor and allow it to communicate with your security system wirelessly. Loop 2 is how you will want to program the 5800MN if you are using it as a contact sensor with its included magnet. Also, the 200 foot nominal range of the 5816 has been retained. And you will enjoy fantastic features like low-battery monitoring, tamper alerts, and RF supervision.

But there are some downsides to the 5800MN that you should consider. The sensor is discontinued, so you will be unlikely to find a new one. But should you come across a used model, it will probably work great. We must admit though, that the 5800MN has a rather dated design. And you will need to replace the CR123A battery periodically. Nonetheless, we like this sensor, and it gets 5 Stars.

Good: Small & Compact, Use as Wireless Transmitter for Wired Contact, 200-Foot Nominal Range, Lots of Features

Bad: Discontinued, Dated Design, Battery Must be Replaced

Bottom Line: 5 Stars
