KX15DTAM Dual‑Technology Volumetric Detector with Anti‑Masking, 15 m, Grade 3, 5‑Year Warranty

Introduction to the KX15DTAM Dual‑Technology Volumetric Detector

KX15DTAM Dual‑Technology Volumetric Detector (15 m) — Grade 3is a wired intruder detector engineered for demanding internal environments where high detection reliability and resistance to tampering are essential. Combining a pyro‑electric passive infrared (PIR) sensor with a microwave sensor in one housing, the KX15DTAM delivers up to 15 m volumetric coverage and includes patented anti‑masking and anti‑blocking capabilities. With EN50131 Grade 3 certification and a 5‑year warranty, this device targets installations that require professional‑grade performance, low false alarms and robust anti‑tamper measures.

Detailed specifications and benefits

The KX15DTAM is designed to meet the needs of professional alarm installers and building security managers. Below are the primary specifications and the benefits they deliver:

• PIR + microwave:The dual‑technology approach requires both sensors to indicate motion before an alarm is triggered. This significantly reduces false alarms that can occur with single‑technology detectors—such as pets, drafts or sunlight—while maintaining reliable human detection.
• Blue Wave Technology and 3D optics:Advanced signal processing helps distinguish valid intrusions from environmental noise. The 3D optics create defined detection zones that improve recognition of human movement across the protected space.
• Independent Floating Thresholds (IFT):This automatic thresholding offers stable operation when ambient temperatures approach body temperature, reducing missed detections or spurious alarms in challenging thermal environments.

• The KX15DTAM includes patented anti‑masking and anti‑blocking capabilities that can detect attempts to obstruct or cover the sensor. It can report masking attempts to the control panel and even prevent arming if the field of view is blocked—an important safeguard in high‑risk sites where intruders may attempt to defeat sensors.
• Anti‑cloaking features further improve robustness by detecting low‑profile attempts to reduce detection probability.

• Selectable microwave channels (3 frequencies):Choose a frequency to avoid cross‑talk with nearby detectors, especially useful in multi‑detector installations or where adjacent rooms are protected.
• On‑board EOL resistors:Pre‑selectable alarm and tamper resistor options simplify wiring and save installation time, reducing the chance of wiring errors at the panel.
• LED indication & tamper protection:Separate LEDs for PIR, microwave and alarm facilitate diagnostics during commissioning. Tamper protection and tamper‑proof brackets are included to meet security installation requirements.

• Certification:EN50131 Grade 3 and CE marked—appropriate for higher‑risk commercial or residential sites that demand robust protection.
• Materials:Durable ABS housing with sealed optics offers longevity in internal environments.
• Warranty:A 5‑year warranty demonstrates manufacturer confidence and reduces total cost of ownership.

Use cases and ideal scenarios

The KX15DTAM excels in situations where higher immunity to false alarms and protection against deliberate tampering are required. Typical applications include:

• Living rooms and open plan areas:Volumetric coverage up to 15 m is well suited to larger internal rooms where movement across a wide area must be monitored.
• Kitchens and conservatories:Environments with variable temperature and sunlight benefit from dual‑technology sensing and IFT temperature compensation.
• Garages and annexes:Spaces that can be targeted for opportunistic entry require Grade 3 detection and anti‑masking to guard against tampering.
• Retail back‑rooms and storerooms:Commercial locations with high value stock benefit from anti‑masking and the robust EN50131 Grade 3 rating.
• High‑risk residential installations:Homes in areas with elevated burglary risk or where owners require more resilient detection than typical consumer detectors.

Because the detector is wired and offers selectable microwave channels, it integrates cleanly into professional alarm systems and multi‑zone installations where control and tuning are important.

How the KX15DTAM compares with similar products

When evaluating intruder detectors, installers typically consider single‑technology PIRs, other dual‑technology detectors, and dedicated anti‑mask sensors. Here’s how the KX15DTAM stacks up:

• Single‑technology PIRs are cost‑effective and simple but can be vulnerable to false alarms triggered by pets, sunlight, drafts or thermal changes. The KX15DTAM’s microwave backup and Blue Wave signal processing significantly reduce false alarms while maintaining strong human detection.

• Many dual‑tech devices offer PIR + microwave, but the KX15DTAM adds patented anti‑masking/anti‑blocking and anti‑cloaking—features not always present on mid‑range models. The selectable microwave channels and on‑board EOL resistors also simplify tuning and wiring compared with some competitors.

• Standards often require anti‑mask capability as a system feature. While separate anti‑mask sensors can be fitted, the KX15DTAM integrates anti‑masking into one device, reducing panel inputs and installation complexity. For sites that require full redundancy, combining multiple anti‑mask-capable devices remains an option.

Representative customer and installer feedback

Actual user reviews vary by site and installer approach. Below are representative, anonymized feedback points based on installer experience with similar Grade 3 dual‑tech detectors:

• "The anti‑masking feature gives customers real peace of mind—being able to detect blocked fields before arming is a big plus for high‑value premises." — Professional installer (anonymized)
• "Selectability of microwave channels and on‑board EOL resistors makes setup faster and reduces callbacks for cross‑talk issues." — Commissioning engineer (anonymized)
• "We’ve seen fewer false alarms in sunlit conservatories after upgrading single PIRs to dual‑tech detectors with digital temperature compensation." — Residential installer (anonymized)
