2GIG-SDS1-345 - Smoke Detector Sensor (Smoke Ring)

2GIG-SDS1-345 - Smoke Detector Sensor (Smoke Ring)
Please Note: The 2GIG-SDS1-345 wireless smoke detector ring has been discontinued without replacement.

2GIG-SDS1-345 Product Description:


The 2GIG-SDS1-345 is a smoke detector sensor designed for use with 2GIG wireless control panels and Honeywell 5800-series compatible wireless control panels. Traditional interconnected smoke detectors are designed to send audible alerts throughout the home if any one of the units detects smoke - but they are not designed to communicate the event to an alarm panel.

Now, DIYer's can add a new layer of protection to a their existing interconnected AC-powered smoke detection system, 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-SDS1-345 "Smoke Ring" smoke detector sensor/transmitter is the ideal solution to make homes even more safe and secure. The 2GIG smoke detector sensor/transmitter (aka "Smoke Ring") works in conjunction with traditional AC powered interconnected smoke detectors to communicate alerts to 2GIG (or other 345 MHz) alarm systems.

The 2GIG-SDS1-345 installs discreetly between the existing AC-powered smoke detector and the ceiling, providing a clean, unobtrusive solution. Utilizing the same AC line (110V AC) powered sensor current that powers the smoke detector, the 2GIG-SDS1-345 will always be "on" and, with a 7+ day battery backup, will even operate during a power outage.

Only one sensor/transmitter is needed when used inhomes outfitted with interconnected, AC-powered smoke detector systems. (No need to install multiple Smoke Ring transmitters). The 2GIG-SDS1-345 is quick and easy to install using existing wiring and clipon connectors. This makes retrofitting a 2GIG "Smoke Ring" onto an existing interconnected smoke detection system a valuable offering for DIYer's.
