Why Can't I Use Z-Wave Security Sensors With My Alarm System?

You can't use Z-Wave security sensors with your alarm system because they are too unreliable. Alarm system manufacturers intentionally design their panels to not support Z-Wave security devices because they do not feel that these sensors are reliable enough for a user to depend upon.

Z-Wave communication technology has made great strides in recent years. The 5th generation of Z-Wave, better known as Z-Wave Plus, has taken the industry by storm in recent times. The Z-Wave Plus devices offer greater range and battery life than standard Z-Wave devices when paired with a Z-Wave Plus Controller. There is even work being done to further improve upon Z-Wave, as Z-Wave 700 Series devices are currently in development.

But while Z-Wave is still improving, the technology just isn't there to rely on the communication protocol for anything outside of smart home automation. This might seem strange considering how well Z-Wave lights, locks and thermostats perform on a consistent basis. But it's important to understand that it can result in a very serious situation if the signal for a security or life-safety sensor ever fails to go through. Alarm system manufacturers don't want to take that chance.

At this time, none of the security systems sold or supported by Alarm Grid support Z-Wave security sensors. Instead, these systems use standardized radio frequency signals for supporting wireless security and life-safety sensors. These frequencies are typically 319.5 MHz (Qolsys, legacy Interlogix/GE), 345 MHz (legacy Honeywell 5800 Series, 2GIG), 433 MHz (legacy DSC), and 915 MHz (PowerG). These frequencies are better-suited for security and life-safety functions than any Z-Wave protocol, which puts them into standard practice. We don't expect this to change any time in the near future.

However, many alarm systems still use Z-Wave technology for home automation purposes. The protocol works great for these functions, and many users appreciate the convenience and energy saving benefits that it presents. So while Z-Wave might not be used for security and life-safety purposes, it is still a great addition for any user who wants to start using automation to make their life more convenient. If your alarm system doesn't already have a Z-Wave controller, you might consider upgrading or adding one so that you can take advantage of these great functions.
