Pyronix KX15DQ 15 m Digital Quad PIR Motion Detector, Grade 2, Sealed Optics — 03452083-e03f-44be-9253-aa958150af2c

Introduction: Meet the Pyronix KX15DQ — 15 m Digital Quad PIR Motion Detector

Pyronix KX15DQ — Wired 15 m Volumetric PIR Motion Detectoris a purpose-built sensor designed for reliable intruder detection in homes, offices and light‑industrial premises. Combining a 15 m volumetric detection range with Pyronixs Digital Quad (DQ) signal processing and Blue Wave3 optics, the KX15DQ aims to deliver consistent performance with reduced false alarms. Its a Grade 2 device (EN50131 series) intended for wired alarm systems and includes sealed aspherical optics, selectable end‑of‑line (EOL) resistor options and both wall and ceiling mounting brackets for flexible installation.

Key Features at a Glance

• 15 m volumetric detectionwith an 85 coverage angle and creep‑zone protection for close‑range detection.
• Digital Quad (DQ) signal processingand Blue Wave3 noise reduction to minimise false alarms from environmental interference.
• Sealed aspherical opticswith white‑light and UV filtering for stable performance in lit environments.
• Adjustable sensitivity— Auto, High and Low — plus digital temperature compensation for consistent detection near body temperature.
• On‑board selectable EOL resistorsfor alarm and tamper circuits to simplify wiring and integration.
• Compliant with industry standards(EN50131 / PD6662) and suited to Grade 2 installations when wired and mounted per specification.

Detailed Specifications and Benefits

• Detection method:Passive Infrared (PIR) with Digital Quad processing. The DQ approach analyses multiple detection elements to confirm genuine motion events and reduce spurious triggers.
• Maximum range:15 m volumetric — suitable for rooms, corridors and medium‑sized areas where broad coverage is required.
• Coverage angle:85, providing a wide field of view while maintaining resolution across 60 detection zones and seven detection planes for accurate motion profiling.
• Lens / optics:Aspherical volumetric lens with sealed optics and white‑light/UV filtering. Sealed optics guard the internal sensor against airborne contamination and reduce sensitivity to environmental light changes, improving reliability.

• Sensitivity modes:Auto, High, Low. Auto mode adapts sensitivity to ambient conditions; manual modes allow installers to tune the detector for specific environments.
• Temperature compensation:Digital temperature compensation ensures the PIR elements maintain detection sensitivity as ambient temperatures approach body temperature, which is critical to avoid missed alarms in warm environments.
• Detection speed:0.3 6.0 m/s — designed to detect typical human movement without being overly sensitive to small pets or brief environmental motion.

• Operating voltage:9 16 V DC (13.8 V typical). Standard for most wired alarm panels.
• Quiescent current:Approximately 13 16 mA @ 12 V — low enough to preserve system power budgets when multiple detectors are used.
• Dimensions & mounting:117  69  50 mm; supplied with wall and ceiling brackets and recommended mounting height 1.8 2.4 m (certified at 2.4 m). Front and rear tamper protection helps secure the sensor from tampering attempts.
• EOL resistor options:On‑board selectable resistors for alarm (6K8, 5K6, 4K7, 1K) and tamper (5K6, 4K7, 2K2, 1K) simplify wiring to panels that require specific end‑of‑line values.

• Standards:Designed to meet EN50131‑2‑2 and related EN50131 standards, plus PD6662 and EN50130‑4 for environmental performance and electromagnetic compatibility.
• Security grade:Grade 2 — appropriate for domestic and low‑to‑medium risk commercial installations.
• Regulatory markings:Confirm CE/UKCA and any local regulatory requirements with your supplier before installation.

Practical Benefits for Installers and End Users

• Reduced false alarms:DQ processing and Blue Wave optics work together to filter out common causes of nuisance alarms, such as electrical IR noise and rapid light changes.
• Flexible installation:Wall or ceiling mounting options and multiple EOL resistor choices make integration with a variety of panels straightforward.
• Durability:Sealed optics improve longevity in dusty or slightly humid environments compared with open‑optic designs.
• Ease of commissioning:Sensitivity modes and temperature compensation reduce time spent tuning the device on site.

Use Cases and Scenarios Where the KX15DQ Excels

• Residential installations:Ideal for homes seeking reliable interior coverage in living rooms, hallways or open‑plan areas. The 85 coverage and 15 m range allow a single detector to cover larger spaces.
• Small offices and commercial premises:Suitable for offices, retail backrooms and meeting rooms where Grade 2 protection is specified. Sealed optics help in environments with fluorescent lighting or air movement.
• Light‑industrial settings:Useful in low‑dust workshops or storage areas where a wired Grade 2 sensor is desired for perimeter or internal detection.
• Mixed lighting environments:The white‑light and UV filtering make the detector more tolerant of brightly lit areas or locations with frequent light switching.
• Systems requiring specific EOL values:On‑board selectable resistors make the KX15DQ a good choice when integrating with panels that enforce particular end‑of‑line supervision values.

How It Compares to Similar PIR Detectors

In the crowded PIR market, detectors vary by optics design, processing sophistication, sensitivity adjustment and installation flexibility. The KX15DQ competes well in several key areas:

• Processing technology:Digital Quad is comparable to other multi‑element processing methods used by major manufacturers. It improves detection confirmation over basic dual‑element PIRs, reducing false triggers without sacrificing detection speed.
• Sealed optics:Many lower‑cost detectors use unsealed lenses that can be prone to dust ingress and erratic behaviour in challenging environments. The KX15DQs sealed aspherical lens and filters offer an advantage in longevity and stability.
• Sensitivity control:The Auto/High/Low modes and temperature compensation give more on‑site tuning flexibility than some basic sensors that offer only fixed sensitivity.
• Price point:With a suggested retail price in the budget to mid range, the KX15DQ is cost‑effective for installers who need Grade 2 performance without a premium price tag.
• Limitations:Some higher‑end detectors provide pet immunity, wireless connectivity or advanced adaptive learning algorithms. If pet immunity or wireless installation is a priority, dedicated pet‑immune or wireless models may be better suited.

Customer Testimonials and Reviews

Direct verified customer reviews for the KX15DQ vary by supplier and region. Installer feedback commonly highlights:

• Reliable day‑to‑day performance and low false alarm rates when correctly mounted and configured.
• Appreciation for the sealed optics and the flexibility of EOL resistor options during panel integration.
• Positive comments about the ease of mounting with supplied brackets and the straightforward sensitivity settings.

Note:Warranty information appears inconsistent in some sources (reports of 2 years vs 5 years). Always confirm the current warranty terms with Pyronix or your supplier before relying on specific warranty claims.

Conclusion: Why Choose the Pyronix KX15DQ?

The Pyronix KX15DQ is a pragmatic choice for anyone specifying a wired Grade 2 PIR for residential, small commercial or light‑industrial use. It balances solid detection performance — 15 m range, 85 coverage and multi‑zone profiling — with practical installer features like sealed optics, selectable EOL resistors and multiple mounting options.
