Wireless Door Sensors and Window Alarm Sensors Posts

Honeywell has discontinued the 5811 sensor and magnet. This popular sensor is the unit that has always been sent out with our most popular kits. It has been replaced by the Honeywell 5800MINI, a smaller, slightly sleeker device with a number of added benefits and improved range.

While not as common in the field as the 5816, the 5811s have, to date, been the contact that anyone looking for a small profile unit have purchased. And while not as thin as the 5820Ls, which are perfect for applications where a window has a very small lip, the discreet 5811 sensors are a well-loved mainstay of the Honeywell line. We are sad to see them go, but are excited about the new 5800MINIs that have replaced them.

For those ordering kits, our images show the old sensor. You will, however, from now on, be receiving the 5800MINIs. We'll be replacing the product shots in short order, but for now, please be aware of the change.

Unfortunately, for those looking to replace old 5811 sensors with new 5811 sensors, we are completely out of stock as is Honeywell. The new 5800MINIs should suffice.

This week, Josh from Connecticut had a pretty standard question a lot of us have before purchasing any wireless products: how long will the battery last?

Specifically, he wanted to know how long the battery in the Honeywell 5811 last. The Honeywell 5811 is a wafer thin door and window sensor that isn't as clunky as its counterpart, the 5816. It's button battery may be small, but it is very very effective.

While the answer to this question is obviously based on usage, I tried my best to answer Josh with a general estimate based on Honeywell specifications and average lifespans on Honeywell CR2032 3V lithium batteries as well as our personal experience with these sensors.

We are proud to announce the addition of the Honeywell 702 and the Honeywell 5899 to Alarm Grid's product offering.

The Honeywell 702 is a self-contained alarm siren that can be used with any wired alarm control panel. Of course, as it is a Honeywell siren, it is recommended that you use it with a Honeywell wired alarm control panel such as any of the VISTA Series alarm control panels. The siren has dual channels so that it can sound a steady alarm and/or a warble alarm. It is also weatherproof which makes it ideal for anyone looking to install a siren outside their home.

The Honeywell 5899 is a replacement magnet designed for the Honeywell 5816 wireless contacts, however you can use the 5899 magnets with nearly any door or window sensor. If you have lost a magnet from your door and window sensor, the 5899 is a great option. Also, the 5899 are great for venting windows which require (2) magnets for each window sensor. To vent the window you simply mount one magnet at the bottom of the window and another magnet a few inches up the window. You then mount the window sensor on the frame across from the top magnet. When the window is closed, the top magnet and the window contact are aligned and when the window is open a few inches, the window contact is aligned with the bottom contact. Now you can have your security system armed and still get a nice breeze flowing throughout your home.
