The 2GIG 'Smoke Ring' is designed as a retrofit solution for interconnected AC-powered smoke detector systems.

The new 2GIG smoke detector sensor (a.k.a. 2GIG Smoke Ring) mounts directly between an existing AC-powered interconnected smoke detector and the wall or ceiling and converts the existing smoke detector into a wireless device that can be used in conjunction with 2GIG GC2 and new 2GIG GC3 alarm panels and systems for more advanced monitoring.

“The new 2GIG Smoke Ring enhances homeowners’ standard AC-powered smoke detector systems by enabling wireless connectivity to a 2GIG GC2 or GC3 alarm panel,” said Avi Rosenthal, vice-president of security and control products for Nortek Security & Control. “Traditional smoke detector systems do a marvelous job of alerting homeowners of an emergency when they’re home, but not if the occupants are away.”

Traditional interconnected smoke detectors are designed to trigger each other and send audible alerts throughout the home if any one of the connected units detect smoke, but many are not equipped to communicate that event directly to the alarm panel.

Unlike other “listening-type” devices on the market, the 2GIG smoke detector sensor does not react to the sound of the interconnected smoke detector but is instead triggered by an electric signal which cuts down on false alarms and increases reliability. Upon alarm, the 2GIG Smoke Ring receives the electrical signal from the connected smoke detector and sends a wireless signal to the paired alarm panel which in turn alerts the proper authorities or homeowner of the emergency via their smartphone or other connected device.

Designed as a retrofit solution for interconnected AC-powered smoke detector systems, only one 2GIG smoke detector sensor is required to monitor the entire house and connect to the 2GIG alarm panel. The 2GIG Smoke Ring allows security dealers and installers to add an additional layer of protection to their customer’s home by providing a professionally-monitored alert signal transmission when smoke is detected by any or all of the interconnected AC-powered smoke detectors.

The 2GIG ‘Smoke Ring’ is UL 217 certified, features a simple three-wire installation and uses the same AC-line current that powers the existing smoke detector to ensure that the sensor is always on.
