Question 1

are they hard wire? (120v with battery backup) and do they have an interconnect wire?

Accepted Answer

In Florida.."703.2Smoke alarms in one-family and two-family dwellings and townhomes.
One-family and two-family dwellings and townhomes undergoing a repair, or a Level 1 alteration as defined in the Florida Building Code, may use smoke alarms powered by 10-year nonremovable, nonreplaceable batteries in lieu of retrofitting such dwelling with smoke alarms powered by the dwelling’s electrical system. A battery-powered smoke alarm that is newly installed or replaces an existing battery-powered smoke alarm as a result of a Level 1 alteration must be powered by a nonremovable, nonreplaceable battery that powers the alarm for at least 10 years. The battery requirements of this section do not apply to a fire alarm, smoke detector, smoke alarm, or ancillary component that is electronically connected as a part of a centrally monitored or supervised alarm system, that uses a low-power, radio frequency wireless communication signal; or that contains multiple sensors, such as a smoke alarm combined with a carbon monoxide alarm or other multisensor devices, and is approved and listed by a nationally recognized testing laboratory."

That last part seems to indicate they would meet code.

Question 2

Will this, if wired to an existing system, trigger a notification if a non-z-wave Alarm goes off (can I buy just one or do I need to replace all)?

Accepted Answer

I don't think this can be wired to an existing system? It doesn't have the receptacles on the back like the wired units do. So, as far as I can tell, you'd have to replace them all. As an aside, I left my wired system in place (4 detectors) and just installed 2 of these. I figured if we're home the wired system will alert us inside the house. If we aren't home the zwave alarms will trigger eventually, but potentially not as quick (depending on source of smoke) without the same number of detectors.

Question 3

How long does the battery last?

Accepted Answer

At first my batteries were reporting 85% after 6 months, and again about 85% after the second 6 months. Then I helped my neighbor in the condo next to me setup a zwave system. Suddenly my batteries are only lasting 4-6 weeks.

In other words, your signal strength will have a lot to do with how long the batteries last.

Question 4

What's the difference between Gen 1 and Gen 2?

Accepted Answer

Practically none. They both are interchangeable. But 2nd generation smoke/CO detector is identified using QR code number ID used when one knows which alarm triggered. Another difference is that 1st generation is w/o zwave Wi-Fi connection to the base station and needs to be connected to the system manually. Zwave option connects it automatically.
