Introduction to the Pyronix FPTMD15G3-3 Twin PIR + X‑Band Microwave Detector
ThePyronix FPTMD15G3-3 (TMD15)is a Grade 3 commercial wired intruder detector that combines a dual‑element passive infrared (PIR) sensor with an X‑band microwave sensor in a single housing. Designed for higher‑risk and commercial environments, this twin‑movement detector delivers volumetric coverage out to 15 m, selectable microwave range, and anti‑mask protection for both sensors. With EN50131 certification, digital temperature compensation, and sealed optics, the FPTMD15G3-3 is built to reduce false alarms while providing reliable dual‑tech confirmation when it matters most.

Detailed specifications and benefits
- Detection type:Dual‑element PIR combined with X‑band microwave for two independent detection technologies.
- PIR range:Up to 15 m volumetric coverage (certified at 2.4 m). This provides broad hemispherical coverage suitable for retail floors, open offices and larger rooms.
- Microwave range:Adjustable from 1 to 15 m. The ability to tune microwave sensitivity helps adapt the detector to reflective or congested environments where microwave spill or reflections could otherwise cause nuisance trips.
- Detection speed:Optimised for human movement between 0.25–2.5 m/s, matching typical intruder motion while reducing sensitivity to small pets or environmental movement.
- Supply voltage:9–16 V DC, compatible with standard commercial alarm panels and SE LV circuits.
- Current consumption:Less than 30 mA (typical), making it suitable for alarm loops without excessive power loading.
- Relay outputs:Three SELV relays rated up to 60 V DC, 50 mA. Separate relays support PIR, microwave and alarm outputs for sequential confirmation strategies.
- On‑board options:Selectable DEOL/EOL resistor settings for straightforward wiring and compliance with panel supervision requirements.
- Dimensions:177 × 70 × 40 mm — a compact footprint that fits standard mounting positions.
- Mounting height:Certified for 1.8–2.4 m (15 m PIR coverage at 2.4 m), enabling standard ceiling and wall placements in commercial settings.
- Anti‑mask:Mask detection operates at approx. 0–1 m, with both PIR and microwave offering coverage against deliberate or accidental blocking.
- Sealed optics:Foam gasket and sealed optical assembly reduce false alarms due to insects and airflow variations.
- IFT technology:Independent Floating Threshold dynamically adjusts sensitivity thresholds to maintain reliable detection while rejecting transient noise.
- Digital temperature compensation:Keeps PIR sensitivity stable across typical temperature variations, lowering the chance of temperature‑driven nuisance alarms.
- LED indicators & tamper:Separate LEDs for PIR, microwave and alarm states, plus front and rear tamper outputs to protect the device from tampering.
Use cases and scenarios where the detector excels
The FPTMD15G3-3 is built for environments that require robust, reliable intrusion detection and a higher assurance of alarm validity. Typical use cases include:
- Retail premises:Large sales floors and back‑of‑house areas where wide volumetric coverage is needed and anti‑masking protects against deliberate concealment.
- Commercial offices and warehouses:Areas with variable environmental conditions or where mechanical disturbances and airflow could otherwise cause false triggers on single‑tech sensors.
- Critical areas and high‑risk sites:Grade 3 certification makes this detector suitable for premises where an elevated risk of intrusion requires improved resistance to tampering and higher detection assurance.
- Protected perimeters inside buildings:Internal corridors and stairwells where dual‑tech confirmation reduces false alarms while maintaining good coverage.
- Zones with potential masking attempts:The anti‑mask capability provides an extra layer of security for sensitive rooms, server areas or storerooms.
Comparison with similar products
When selecting intruder detectors you typically encounter three main categories: single‑tech PIR detectors, microwave‑only devices, and dual‑tech (hybrid) detectors. The FPTMD15G3-3 sits in the dual‑tech category but has specific advantages to note:
- Single‑tech PIR vs FPTMD15G3-3:Traditional PIR units are cost‑effective and perform well in stable indoor environments but are more susceptible to false alarms from airflow, insects or rapid temperature changes. The FPTMD15G3-3 adds microwave confirmation, IFT, sealed optics and temperature compensation to substantially reduce nuisance trips.
- Microwave‑only vs FPTMD15G3-3:Microwave‑only detectors can detect through some obstructions and are sensitive to metallic movement and reflections. However, without thermal confirmation they may trigger on non‑human motion. The Pyronix twin unit requires sequential confirmation or relay logic to validate an alarm, improving accuracy.
- Other dual‑tech detectors:Many dual‑tech devices offer combined PIR and microwave sensing; the FPTMD15G3-3 distinguishes itself with Grade 3 certification, selectable microwave range up to 15 m, on‑board DEOL/EOL options and anti‑mask on both technologies. For installations that require official standards compliance and anti‑mask capability, it is a strong candidate.
Customer feedback and installer impressions
While individual reviews vary by site and installer preference, common feedback themes from installers and end users for this class of Pyronix detector include:
- "Easy to configure on site — selectable microwave range and EOL options make wiring and tuning straightforward."
- "Reliable in busy retail areas — reduced false positives compared to older PIRs thanks to sealed optics and IFT."
- "Grade 3 certification and anti‑masking give peace of mind for higher‑risk clients and critical zones."
- "Good value for a Grade 3 dual‑tech unit, especially with the five‑year warranty backing the product."
Note: These are representative installer and user comments summarising typical experiences with the product type. Site‑specific results depend on correct mounting height, tuning and adherence to the manufacturer’s datasheet.
Compliance, installation and practical considerations
The FPTMD15G3-3 is certified to EN50131‑2‑4 and EN50131‑1 and is listed under PD6662 guidelines. It is classified as Environmental Class II, making it suitable for standard indoor commercial environments. To achieve the best performance and maintain compliance:
- Have a qualified alarm engineer perform the installation, set the microwave and PIR sensitivity per the site survey, and select the appropriate DEOL/EOL resistor configuration.
- Observe the recommended mounting height (1.8–2.4 m) and ensure the PIR field of view is unobstructed for the certified 15 m volumetric coverage.
- Use the anti‑mask functionality appropriately — test mask detection during commissioning to ensure the expected coverage and nuisance immunity.
Conclusion: Why choose the Pyronix FPTMD15G3-3?
For installers and end users who need a robust, standards‑certified dual‑tech detector for commercial or higher‑risk environments, thePyronix FPTMD15G3-3offers a balanced blend of coverage, configurability and false‑alarm management. Its 15 m PIR volumetric range, adjustable 1–15 m microwave, anti‑mask protection on both sensors, and Grade 3 certification make it particularly well suited to retail, commercial premises and critical areas where reliability and compliance are non‑negotiable. Add low current draw, selectable wiring options and a five‑year warranty, and the detector represents strong value for money — a suggested retail price of around {75.00} (check local pricing) aligns with its specification and warranty backing.
Ultimately, when correctly specified and installed by a competent engineer, the FPTMD15G3-3 reduces nuisance alarms while providing the increased detection assurance required for sensitive or high‑risk zones. That combination of performance, standards compliance and practical installer features is why it remains a compelling choice for commercial intrusion detection projects.
