Feedback from the system can be easily gained in other ways. I like to stick a bicolored LED up in a soffit by where the end user drives in/out.drvnbysound said:Honeywell does offer keyfobs. However, their fobs don't have the 2-way capability to provide you with feedback from the system (e.g. system status; armed, disarmed). Here's a link to the Honeywell ones: https://www.security.honeywell.com/hsc/products/intruder-detection-systems/wireless/remote-control/ademco/300524.html
Here's another link that shows all of the Honeywell 5800 series wireless products: https://www.security.honeywell.com/hsc/products/intruder-detection-systems/wireless/index.html
I can't see the benefit of pigeonholing a system with Elk's RF. They market a good game with the bidirectional feature and perceived value and performance, but does an end user really notice the difference? Elk has 2 unique devices (PIR with the LED light and tandem RF smokes) and less detector variety.
