The Honeywell 5843 is a wireless switch module that you can control using a Honeywell 5834-4 Key Fob or any other Honeywell 345 MHz Key Fob. The purpose of the Honeywell 5843 is to control a connected relay device wirelessly using a key fob input. The way that this works is that you must connect a Normally Open or Normally Closed relay-activated device to the 5843. You then program a compatible key fob, such as a Honeywell 5834-4, to the 5843 device. You will only need to program one (1) specific key fob input to the 5843. Then, whenever you make that input on the key fob, it will activate the relay, and in turn, the connected device, provided that the key fob is within wireless range of the 5843. Alarm Grid likes the Honeywell 5843, and we give it a 5 Star rating.

There are many aspects that we appreciate about the Honeywell 5843. For one, it allows for both Normally Open and Normally Closed relay devices, so you can wire it in the manner that is most convenient for you. You can also choose any button on your compatible key fob for controlling the connected device. The option to choose between a 12VDC transformer and a 9VAC transformer provides added flexibility. And the LED light on the device is a nice touch, as it is useful for troubleshooting and providing status.

But there are some downsides to the 5843 that should also be considered. For one, it only works with Honeywell 345 MHz Key Fobs, which is a somewhat limited selection. Also, the device that is being controlled must be physically connected with the 5843. And even then, the wireless range is limited by the key fob device that is being used. These downsides are minor though, and they do not stop us from giving the 5843 a 5 Star score.

Good: NO & NC Wiring, Choose Any Fob Button, Transformer Options, LED Light

Bad: Only Works w/ Honeywell 345 MHz Fobs, Controlled Device Must Be Connected, Limited Fob Range

Bottom Line: 5 Stars
