  • 1165 Wireless Commercial Smoke Detector Lifetime Buy TU-0920

There are a limited number of 1165 Wireless Commercial Smoke Detectors available for a final lifetime buy to support the discontinued line of XR100/XR500 Series systems. The 1165 was discontinued on July 10, 2017.

For XR150/XR550 Series systems, we recommended replacing the 1165 with 1164 or 1164NS Series Wireless Smoke Detectors. The 1164 offers several additional features that the 1165 does not. These features include synchronized sounders and a more competitive price point. The 1164/1164NS Series is not compatible with XR100/XR500 Series systems.

1165 Wireless Commercial Smoke Detectors can be ordered by contacting DMP Customer Service at 1-800-641-4282 or by visiting
