Yale AC-DC Door/Window Contact review

Yale AC-DC Burglar Alarm Door / Window Contact

By Tom Calder

Our verdict · Researched
3.5 / 5

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

ⓘ As an Amazon Associate, PreparedBritain earns from qualifying purchases. We may earn a commission when you buy, or a fee when you request a quote, through our links. When two products are close, commission can decide which one we pick. A clearly better product always wins. Amazon prices come from Amazon's own product data and show the date and time they were retrieved. Prices at other retailers are checked by us, less often. Prices and stock can change at any time, so always check the retailer's price before you buy.

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.

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.
