KiddeKE-DP3021W Addressable Dual Optical Smoke + Heat Detector

KE-DP3021W, a Kidde Excellence series addressable multi-sensor smoke + heat detector. The smoke chamber is scanned in forward and reverse directions using two separate optical wavelengths. This dual-angle measurement enables discrimination of particle size: true fire smoke is distinguished from dust and vapor, significantly reducing unwanted alarms. Heat sensor is added to optical detection; the same device can be reconfigured by neighborhood according to the operating mode selected from the control panel. All three alarm levels are certified EN 54. Coverage area up to 112 m², mounting height up to 10.5 m. Address is set directly as a number using two rotary switches — no binary or hexadecimal conversion required, reducing the risk of incorrect addressing. Three-color LED indicator is visible at 360°; no need to align in the corridor to locate the alarming detector. Non-isolated version; projects requiring isolation use the 31xx series equivalent. Self-testing and contamination compensation; generates warning when maintenance is required. Mounts on standard KE-DB3010W base; all detectors in the series use the same base, allowing field device replacement without removing the base. Operating voltage 17–29 VDC, operating temperature -10…+55°C, protection class IP20.
