Kidde Commercial KE-DP3020W | Addressable Dual Optical Smoke Detector | Dual Wavelength Discrimination, Tri-Colour Status LED, IP20
£25.78 (inc VAT: £30.94)
Summary
The Kidde KE-DP3020W is an intelligent addressable dual optical smoke detector built to cut false alarm callouts and speed up commissioning on commercial fire systems. If you’re tired of nuisance alarms triggered by steam or dust on site, this detector’s dual wavelength optics are designed to tell the difference between real smoke and everyday environmental interference.
For you as the installer, that means fewer return visits, a smoother handover, and a system that’s easier to defend at sign-off. The rotary switch addressing uses a direct, human-readable number rather than binary or hexadecimal codes, so there’s less room for addressing errors during first-fix or re-commissioning.
All alarm levels on the KE-DP3020W are EN 54 certified, and the detector carries EN54-7 certification, giving you a documented basis for compliance on BS 5839-1 commercial fire installations. It’s part of the wider Kidde Excellence range, so it shares a common base and protocol with other Excellence series devices for straightforward system planning.
Features
- Dual optical wavelength detection - differentiates real smoke from steam and dust for genuinely fewer false alarms
- Tri-colour 360° status LED - shows alarm, pre-alarm, isolation, fault, ItsMe and communications status from any viewing angle, no device alignment needed on install
- Remote indicator output - drives a remote indicator up to 30m away with short-circuit isolation to protect the rest of the loop
- Mechanical rotary addressing - two rotary switches set a direct address number, removing the risk of binary or hex conversion mistakes
- Automatic self-testing and drift compensation - flags contamination before it becomes a fault, supporting planned maintenance visits
- Event logging - stores diagnostic history in the device itself, useful when troubleshooting intermittent faults on a call-back
- Standard Excellence base compatibility - fits the KE-DB3010W base, so detectors are interchangeable across the range without replanning wiring
- Scorpion tester compatible - lets you test detectors in awkward or inaccessible locations without access equipment
- Legacy protocol support - the Excellence communication protocol still talks to older Kidde 2000 series devices, useful on phased upgrades
- Loop powered design - low quiescent current of 140µA at 24VDC keeps loop loading manageable on larger systems
FAQ
How is the address set on site, and does it need a separate programming tool?
Addressing uses two mechanical rotary switches on the detector, which display a direct, human-readable number rather than a binary or hexadecimal code. No handheld programmer or software tool is required, which reduces the risk of addressing errors compared with older DIP-switch detectors.
Does this detector need a specific base, or will it work with other manufacturers' bases?
The KE-DP3020W is designed for the Kidde KE-DB3010W standard Excellence series base, and this is the only base combination Kidde confirms on the datasheet. Fitting the head to a base from a different manufacturer’s range isn’t covered by this documentation, so correct device type reporting and fault indication can’t be assumed; check with the panel and base manufacturer before mixing ranges.
Does the KE-DP3020W meet EN54-7, and does that affect which panels it can be used with?
Yes, the detector is certified to EN54-7 (the European Norm for point smoke detectors) under the Construction Products Regulation (CPR). Compliance with this standard confirms the detector’s own performance, but it doesn’t guarantee compatibility with a specific panel; that depends on the panel manufacturer supporting the Kidde Excellence series protocol.
Are short-circuit isolators built into this detector, or do I need separate isolator modules on the loop?
Short-circuit isolation is built into the remote indicator output, protecting the loop if that wiring is damaged. The datasheet doesn’t specify a separate loop isolator within the detector itself, so if you need isolation at set points around the signalling line circuit, this should be confirmed against the panel manufacturer’s loop design rules.
What causes nuisance alarms in dusty or steamy environments, and can sensitivity be adjusted?
The KE-DP3020W uses dual optical light-scatter sensing across two wavelengths, which helps the detector distinguish genuine smoke from dust, steam or other airborne particles that trigger false alarms in single-wavelength detectors. Sensitivity is selectable, allowing it to be tuned to the environment, though final settings should be checked against the manufacturer’s guidance for the specific application.
What's the maximum mounting height for this detector?
Kidde specifies a standard installation height of less than 10.5m, extending to less than 12m where reduced detector spacing and a documented risk assessment are applied. For heights near these limits, check the full design guidance and verify spacing calculations against BS 5839-1 for the building in question.
