The ADT 4 Wire Smoke Heat Detector has been discontinued and the recommended replacement is this one.  The ADT 4 Wire Smoke Heat Detector is a detector that gives you the best of both worlds. This detector has a sensor built in to detect both smoke and heat, giving you double the protection. Additionally, it has a removable smoke chamber that makes it easy to maintain.  Its low profile design also ensures that this device will not be an eyesore in your home.

But if this detector isn’t what you’re looking for, please also check out our other smoke detectors.

Note: This product only includes one detector.
