Kidde Commercial KE-DP3021B | Addressable Dual Optical Heat Detector | Dust & Steam Discrimination
£44.48 (inc VAT: £53.38)
Summary
The Kidde Commercial KE-DP3021B is a loop powered addressable detector built to cut false alarm callouts on commercial fire systems, combining dual optical wavelengths with heat sensing in one head. If nuisance alarms from dust, steam or cooking fumes have cost you site visits before, this is the detector that gets specified to stop that happening again.
For you on site, that means fewer return trips, a straightforward commissioning process and a device that’s easy to defend at handover. Two rotary switches set the address as a plain number, so there’s no binary or hexadecimal conversion to get wrong when you’re up a ladder with a torch in one hand.
Detection reliability comes from multiple detection angles and dual optical wavelengths that differentiate real smoke particles from nuisance sources, backed by Class A static and rate-of-rise heat detection for a wider application footprint. The KE-DP3021B is certified to EN54-5 and EN54-7, supporting compliance on systems designed to BS 5839-1.
Features
- Dust and steam discrimination - fewer nuisance alarms and fewer unnecessary site visits
- Self-testing and drift compensation - contamination warnings flag maintenance before a fault occurs
- Rotary switch addressing - set a direct numeric address without binary or hex conversion
- Remote indicator output - drive a remote LED up to 30m away with short circuit isolation for extra protection
- Tri-colour LED with 360° visibility - alarm, pre-alarm, isolation, fault and communication status readable from any angle without aligning the head
- Event logging - on-device history helps you diagnose issues without pulling the detector
- Static and rate-of-rise heat detection - Class A performance widens the range of environments the detector suits
- Standard Excellence base compatibility - simplifies planning and makes detectors interchangeable across a site
- Legacy protocol support - the Excellence protocol still communicates with Kidde 2000 series devices on the same loop
FAQ
How do I address devices on site - is it done at the panel, on the detector, or with a separate programmer?
Addressing is set directly on the detector using two rotary switches that display a straightforward numeric value, so no binary or hexadecimal conversion is needed and no separate programming tool is required. Because the address is held on the head rather than the base, swapping a faulty detector for a spare is quick.
Does the KE-DP3021B need a specific base, and can I fit a head from another manufacturer's range on it?
This detector is designed for the Kidde Excellence series standard base, listed as the KE-DB3010B. The datasheet doesn’t cover compatibility with third-party bases or heads, so if you’re mixing ranges, confirm with Kidde Commercial that the panel will still report the correct device type and fault conditions before specifying.
How far can the remote indicator be installed from the detector?
The remote indicator output supports cable runs of up to 30m and includes short circuit isolation to protect the rest of the loop if that circuit is damaged. The output itself is rated at less than 8mA and is not programmable.
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 specific circuit is damaged. The datasheet doesn’t specify a full loop isolator within the detector head itself, so where loop-wide isolation is required, check the panel and loop design with the manufacturer or system designer.
What ceiling height is this detector suitable for?
Standard installation height is up to 7.5m, extending to 9m where reduced spacing and a risk assessment support it. Check your building layout and spacing against BS 5839-1 guidance before finalising detector positions.
Is sensitivity adjustable, and does that affect EN 54 compliance?
Sensitivity is selectable on the device, and the detector holds certification to EN 54-5 (heat) and EN 54-7 (smoke). For the exact adjustment procedure and available settings, refer to the full installation manual.
