Kidde Commercial KE-DP3021W | Addressable Dual Optical Heat Detector | Nuisance Alarm Discrimination, 360° Indicator Visibility
£32.48 (inc VAT: £38.98)
Summary
The Kidde Commercial Excellence KE-DP3021W is a dual optical and heat detector built for installers who need reliable, low-nuisance fire detection on commercial addressable systems. It combines forward and backward optical light scatter with heat sensing, so a single head covers a wider range of fire signatures without triggering false alarms from steam or dust.
For you on site, that means fewer callbacks and less time explaining nuisance activations to the client. The two rotary address switches set a direct, readable device number rather than a binary or hexadecimal code, cutting commissioning errors and speeding up multi-device installs. Event logging built into the device also gives you a diagnostic trail if a fault needs investigating later.
Detection sensitivity across all levels is EN 54 certified, and the detector is built to EN 54-5 and EN 54-7 with Construction Products Regulation (CPR) certification, so it slots straight into compliant commercial fire detection design.
Features
- Dual optical and heat detection - one head covers optical and thermal alarm conditions, reducing device count on a project
- Nuisance alarm, steam and dust discrimination - fewer false alarms from cooking steam, dust or similar sources on real installs
- Remote indicator output with short circuit isolation - drives a remote indicator up to 30m away without risking the loop if the cable faults
- Rotary switch addressing - two clearly marked dials set a direct device number, no binary or hex conversion needed on site
- Tri-colour status indication with 360° visibility - alarm, pre-alarm, isolation, fault, ItsMe and communications states are readable from any angle, no need to align the device on the ceiling
- Static and rate-of-rise heat detection - Class A response widens the application footprint beyond a simple fixed-temperature detector
- Automatic self-testing and drift compensation - ongoing contamination monitoring flags maintenance needs before they become false alarms
- Event logging - on-device history supports fault diagnosis without needing to pull data from the panel
- Standard base compatibility - works with the Excellence series KE-DB3010W base, simplifying planning and swap-outs
- Legacy protocol support - the Excellence communication protocol still talks to legacy Kidde 2000 series devices on the same loop
FAQ
Which base does the KE-DP3021W need?
It’s designed to fit the Excellence series KE-DB3010W standard base. As all Excellence series detectors share this base, a single base type covers mixed detector types across a project.
Can I mix this detector with other manufacturers' devices on the same loop?
The KE-DP3021W is designed for compatibility with Kidde Commercial Excellence series systems; the datasheet does not confirm interoperability with other manufacturers’ loop devices. Confirm with your panel manufacturer before specifying a mixed-vendor loop.
How do I address this detector on site?
Addressing is done directly on the device using a rotary switch, with no binary or hex coding and no separate programmer tool required. This makes on-site commissioning straightforward for engineers without dedicated addressing equipment.
How far can the remote indicator be from the detector?
The remote indicator output can run up to 30m from the detector, with a maximum output current of less than 8mA. Check the current draw of the specific remote indicator you’re fitting against this rating before specifying a longer cable run.
What installation height is this detector rated for?
Standard spacing supports installation heights up to 7.5m. This can be extended to under 9m where reduced spacing is used and a documented risk assessment supports it, so factor this into surveys for taller commercial spaces.
What causes nuisance alarms in dusty or steamy environments, and can sensitivity be adjusted remotely?
The dual optical and heat sensing is intended to help discriminate genuine fires from conditions like dust or steam that can trigger optical-only detectors. Sensitivity is selectable on the device, but the datasheet doesn’t specify whether this can be adjusted remotely from the panel, so check your panel’s software capabilities or the full installation manual to confirm.
