Yale AC-DC Door/Window Contact review
Yale AC-DC Burglar Alarm Door / Window Contact
By Tom Calder
A straightforward, wire-free add-on sensor rather than a standalone alarm. It does its one job — flag when a monitored door or window opens — reliably, but only if you already have a compatible Yale panel to plug it into.
- Best for
- Households who already own a Yale Sync or Yale Intruder wireless alarm panel and want to add contact coverage to one more door or window.
- Skip it if
- You don't already have a compatible Yale alarm panel installed

Researched, not used. We haven't used this product. This review is built from the maker's specifications, owner reports and our own sizing.
What we like
- Wire-free magnetic contact, straightforward DIY fit
- Anti-tamper protection and a low-battery warning
- Claimed 200m wireless range to the panel, battery included in the box
Worth knowing
- Not a standalone alarm — no siren of its own, and it needs an existing compatible Yale panel to do anything
- No smart-app features by itself; any phone alerts come from the paired Yale Sync system, not this unit

Who shouldn't buy this
Don't buy this if you don't already have a compatible Yale alarm panel installed — on its own it does nothing; you'd need a full kit, not just a sensor.

If this isn’t the one

Best for Homeowners wanting whole-house DIY alarm coverage — doors, windows, motion, an indoor camera and an outdoor siren — set up in one go rather than bought piecemeal.
