The Honeywell 5817 is a wireless three zone sensor. Unlike other Honeywell wireless window and door sensors, the 5817 does not have an internal reed switch or magnet and therefore cannot be used as a window or door contact by itself. Instead, you must connect a wired contact loop to the 5817 transmitter which will then send all alarm signals back to your Honeywell wireless home alarm system. The 5817 sensor actually has (3) separate loops (or zones) so that you can connect (3) different wired contact loops to the transmitter.

What makes the Honeywell 5817 so valuable is that the first contact loop can be set as a normally open loop. While most devices are normally closed and require a normally closed loop, certain devices actually need a normally open loop. Nearly all of these normally open devices are wired and you would therefore not be able to use them with a wireless alarm system. The 5817 wireless sensor gives you an option to use wired normally open devices with a wireless alarm system. The first loop can also be setup as a repeating transmission so that it sends a signal every 4 seconds while in alarm condition. This type of transmission would be used for high priority alarms such as fire or carbon monoxide. You can also set the first loop to be either slow response time (200mSec normally closed) or fast response time (5mSec normally closed). All of these settings are selectable using the internal dip switches. You should have all dip switches set to the off position while enrolling the 5817 wireless sensor to your Honeywell wireless alarm system.

The second and third auxiliary contact loops of the 5817 sensor are both normally closed loops with a nominal response time of 100mSec. If you are not going to use all of the loops, you can leave the terminals empty for the unused loops.

The 5817 wireless sensor has an included lithium battery should that should last 3-5 years. When the battery is nearly dead, the 5817 will send a low battery signal to your wireless alarm system so that you have time to replace it before it dies completely.


They 5817 was replaced by the 5817XT part number so they are essentially the same item. The 5817 did have a 100MSEC response time while the newer 5817XT has a 320MSEC response time but aside from that, they are the same device.
Hello. What's the difference between the 5817 and the 5817XT ? Thank you
The 5817 has a nominal range of 200 feet.
