What is the Honeywell SD365CO?

SD365CO combination fire and carbon monoxide (CO) detectors are addressable detectors that send separate signals for fire and CO. These multi-criteria detectors use four sensing technologies (photoelectric, infrared, heat, and CO) to accurately detect fire and CO alarm conditions and have a high immunity to false alarms. When paired with the B200S-WH sounder base or B200S-LF-WH low frequency sounder base, the SD365CO detectors can generate unique alarms for fire and CO events. Features & Benefits:

Detects both life-threatening carbon monoxide (CO) leaks and fires in one device

10 year CO cell life span

Eliminates the need for separate detectors and additional hardware

Modern design with white finish

Low standby current

Rotary address switches for fast installation

Meets UL 2075 and 268 for CO detection

Compatible with ES-50X and ES-200XCertifications:

UL: S1059

UL Standard: 268

CSFM: 7272-0075:0507
