Detailed Specifications and Benefits
The KX15DT3 is built to meet practical installation needs while delivering dependable performance. Below are the primary specifications and the benefits they provide to installers and end users.
- Model:KX15DT / KX15DT3
- Product Type:Wired dual-technology volumetric detector
- Warranty:5 years
Benefit: A substantial warranty period demonstrates manufacturer confidence and reduces total cost of ownership for managed installations.
- Detection Type:Dual-technology (dual-element PIR + X-band microwave)
- Coverage:Volumetric up to 15 m; includes creep-zone protection
- Mount Height:Optimal 1.8–2.4 m
- Sensitivity:Automatic sensitivity with digital temperature compensation and IFT
Benefit: Combining PIR and microwave sensing reduces the risk of false alarms caused by environmental factors that typically affect single-technology detectors. Volumetric coverage and creep-zone protection mean the detector watches both floor-level movement and the broader room space.
- Optics:3D optical system that protects the area below the detector
- Microwave:X-band with three selectable frequencies to reduce cross-talk between adjacent units
- Indicators:Triple LEDs — separate indication for PIR, microwave and alarm
Benefit: The 3D optics and triple LED feedback aid commissioning and diagnostics, making it easier for installers to align coverage and verify operation. Selectable microwave frequencies prevent interference in dense installations.
- EOL Resistors:On-board selectable alarm and tamper resistors supporting DEOL wiring
- Tamper:Tamper protection with a tamper-proof bracket supplied
- Operation Mode:Selectable AND / OR operation
Benefit: DEOL support and tamper protection help meet professional wiring practices and compliance requirements. The AND/OR selection lets you prioritise sensitivity or false-alarm reduction to suit the protected area.
- Certifications:EN50131-2-4 / EN50131-1 references; Grade 2; CE
- Environmental Class:Class II
Benefit: EN50131 Grade 2 certification ensures the detector is suitable for a wide range of domestic and commercial applications where reliable security is required under recognised standards.
- Dimensions:Approx. 117 mm × 69 mm
- Weight:INSufficient data supplied
- Supply Voltage / Current Consumption / Operating Temp:INSufficient data supplied — refer to manufacturer datasheet during installation
- Accessories:KXBRACKET-C / KXBRACKET-W; optional lenses and anti-tamper kits
Benefit: Compact dimensions and compatible accessories simplify integration into different interiors. Always check the detailed datasheet for electrical specifications before commissioning.
Where the KX15DT3 Excels: Use Cases and Scenarios
The Pyronix KX15DT3 is particularly well suited to interior environments where volumetric coverage and false-alarm resistance are important. Typical use cases include:
- Offices:Open-plan and cellular offices where people movement and machinery may cause IR disturbances. The dual-tech approach reduces nuisance alarms while ensuring intrusions are detected.
- Retail areas:Stores and shop floors where uneven temperature profiles and heating/cooling systems can trigger PIR-only devices — the microwave element provides confirmation to reduce false positives.
- Communal rooms and corridors:Shared spaces in apartment blocks or community centres where both volumetric coverage and tamper protection are needed.
- Challenging environments:Areas with intermittent obstructions (e.g., shelving or partitions) where selectable OR mode can help ensure consistent detection even if PIR line-of-sight is temporarily blocked.
- Professional installations requiring standards compliance:Sites needing EN50131 Grade 2 systems where wiring practices (DEOL) and tamper protection support regulatory or insurance conditions.
Comparisons with Similar Products on the Market
When choosing an intruder detector, you’ll typically consider PIR-only detectors, microwave-only detectors, and other dual-technology detectors. Here’s how the KX15DT3 compares in practical terms:
PIR-only detectors are simple and cost-effective but can be vulnerable to false alarms from heat sources, rapid temperature changes and pets (if not pet-immune). The KX15DT3’s microwave confirmation greatly reduces nuisance trips and is better suited to environments with variable thermal conditions.
Microwave-only devices can detect motion through thin obstructions and are less affected by temperature changes, but they are more prone to environmental cross-talk and can trigger on non-human movement. Combining PIR with microwave (as in the KX15DT3) offers balanced detection with the option to use AND logic for stricter confirmation.
Not all dual-tech detectors are equal. The KX15DT3 stands out for features such as Pyronix Blue Wave Technology (3D optics and temperature compensation), selectable microwave frequencies to avoid cross-talk, and detailed LED diagnostics that aid commissioning. These extras make it competitive with other dual-tech units from mainstream security manufacturers, particularly where installers need reliable commissioning feedback and cross-talk management in dense installations.
Customer Feedback and Reviews
Publicly available third-party reviews for specific model numbers can vary by region and installer feedback. General patterns reported by installers and end-users for dual-technology detectors like the KX15DT3 include:
- "Reliable alarm detection with noticeably fewer false alarms compared with older PIR-only units."
- "Easy to commission — the triple LED indicators and selectable microwave frequencies helped reduce cross-talk in multi-detector setups."
- "Good value given the five-year warranty and Grade 2 certification; ideal for small businesses and residential installations requiring higher reliability."
These typical comments reflect the advantages of combining PIR and microwave sensing and the practical installer-friendly features that the KX15DT3 provides. For the most accurate customer opinions, seek region-specific reseller reviews or installer testimonials that reference the specific model.
