Z-Wave enabled battery operated photoelectric smoke/CO combo alarm. It will NOT WORK with the Onelink System! It is compatible and will link the hubs from Nexia Home Intelligence, Iris Smart Hub, and other Z wave technologies. BRK ZCOMBO-G has been fully tested and complies with, UL217, UL2034, CSFM, NFPA 72, NFPA 720 and NFPA 101 and other agencies that model their codes after the above agencies. It meets building codes where battery operated Z-Wave wireless smoke and CO alarms are required along with silence features and with model building codes published by the ICC.

BRK ZCOMBO-G is a state of the art wireless combination smoke and CO alarm designed to provide early warning of a fire or CO. It features a fully insect screened Photoelectric smoke sensing chamber and an electrochemical carbon monoxide sensor, an 85dB horn, a supervised 3V (2 AA batteries) power supply, a full function test switch and a silence feature. This combination alarm will operate with 3rd party, certified Z-Wave devices and the basic command class required by all Z-Wave devices. By the requirements of the Device Class spec, this command class does not have to be mapped to any particular functionality for this device. The alarm supports one association group with up to 1 node, and sends its alarms to that group. The alarm supports configuration parameter #1, which has a size of 1, a default value of 0, and when set to 1 causes the device to send double alarm messages.

It also features tamper resistant locking pins that lock alarm to the mounting bracket and battery drawer to prevent removal of battery or alarm. Perfect for apartment, dormitory or hotel applications. Designed for wall or ceiling mounting. Includes mounting anchors and screws.

Great service January 2, 2018
Reviewer: Nathan Biar from Mililani, HI United States  
I was looking for a z-wave compatible smoke alarm to integrate with my Smartthings setup. While I would've preferred a hard wired version (no one makes on that I know of at the time of this review), the battery version is working as I want it to. Now if it goes off, I can have it trigger lights or other alerts if I am not home.

Smoke Alert had lower prices than the big online company and had it in stock. Living in Hawaii, I was expecting shipping to take a while, but the detector showed up very quickly. I definitely recommend buying from smokealert and will be coming back myself to buy another z-wave detector in the near future.
