Ceiling 360° Quad PIR Motion Detector, 12 m Range, 12 V DC, Grade 2 OCTOPUSDQ

Introduction to the Octopus DQ (OCTOPUSDQ) and its key features

The Pyronix Octopus DQ is a ceiling‑mounted, wired 360° quad PIR motion detector designed for commercial and residential intruder alarm systems. With a 12 m detection diameter, Blue Wave digital signal processing, selectable pulse count and Grade 2 security certification, the Octopus DQ offers broad volumetric coverage with reliable nuisance alarm resistance. It is purpose‑built for overhead protection of retail areas, corridors, storerooms and shared spaces where unobtrusive ceiling mounting and high immunity to false alarms are priorities.

Key features at a glance include:

• 360° volumetric detection— 156 detection zones across three planes for full overhead coverage up to 12 m diameter.
• Quad‑interlocking pyroelectric sensorwith selectable pulse count (1/2/3) for tailored sensitivity profiles.
• Blue Wave DSP with temperature compensation and IFT— reduces false alarms and improves interference immunity.
• Installer‑friendly design— single‑screw ceiling mounting, clip‑in PCB, selectable EOL resistors and a walk‑test LED.
• Tamper protection and solid‑state outputs— front and rear tamper; outputs rated up to 60 V DC, 50 mA.
• Certified— compliant with EN50131 standards, PD6662 listed and Security Grade 2. Backed by a 5‑year warranty.

Detailed specifications and benefits

The Octopus DQ’s quad‑interlocking pyroelectric elements create a high‑resolution detection pattern distributed across three planes. This delivers 156 distinct zones that combine to form seamless 360° volumetric coverage. At the recommended mounting height (2.4–4.0 m, optimum at 4 m), the detector provides an effective detection diameter of up to 12 m. Detection speed is optimised for pedestrian movement (0.3–3.0 m/s) and the typical response time is approximately 2.5 seconds.

Selectable pulse count (1, 2 or 3) lets installers tune sensitivity to match the application. Lower pulse counts increase sensitivity for smaller movements, while higher counts increase robustness in challenging environments where transient events might otherwise trigger an alarm.

At the heart of the Octopus DQ is Pyronix’s Blue Wave digital signal processing (DSP). Blue Wave combines temperature compensation and Independent Floating Threshold (IFT) technology to maintain consistent detection sensitivity across changing ambient conditions and to discriminate true human motion from electrical or environmental noise. This combination significantly reduces nuisance alarms caused by factors such as air conditioning drafts, sunlight variation, or small thermal fluctuations—common issues in many ceiling‑mounted installations.

Electrically the detector operates from 9–16 V DC (nominal 12 V DC). Quiescent current is approximately 15 mA, and alarm current is around 25 mA at 12 V DC, making it well suited for typical alarm panel power budgets. Outputs are solid‑state and rated for up to 60 V DC, 50 mA max, with selectable EOL resistor values supported for compatibility with a wide range of control panels and wiring practices.

Physically the Octopus DQ is compact (Ø 94 × 33 mm) and light (≈ 62 g), with single‑screw ceiling mounting and a clip‑in PCB for fast installation. Tamper protection is provided for both front and rear access. Environmental ratings permit operation between −10°C and +40°C, with storage to −40°C/+80°C and Environmental Class II designation.

The OCTOPUSDQ meets EN50131‑2‑2 and EN50131‑1 requirements, is listed to PD6662 and is classified as Security Grade 2—suitable for many commercial and higher‑risk residential installations. A 5‑year manufacturer warranty provides additional assurance for installers and end users.

Use cases and scenarios where the Octopus DQ excels

• Retail floor coverage— The 360° ceiling coverage is ideal for open retail spaces, showrooms and shop floors where wall‑mounted beams would leave blind spots or be visually intrusive. The detector can be mounted centrally to protect aisles and display areas with minimal aesthetic impact.
• Corridors and communal spaces— In apartment blocks, office floors and communal corridors the Octopus DQ provides unobtrusive overhead protection that covers movement through shared spaces without requiring multiple wall sensors.
• Storerooms and back‑of‑house areas— For storage rooms and stock areas with shelving and varied layouts, the multi‑plane detection and selectable pulse count help ensure people movement is detected while minimising false alarms from HVAC or machinery.
• Low‑profile security installations— Where visible security hardware is undesired—such as boutique shops, museums or heritage interiors—the compact ceiling sensor offers discreet protection.
• Multi‑panel and common area integration— The EOL resistor options and solid‑state outputs make panel integration straightforward for systems requiring supervised circuits and compliance with signalling standards.

Comparisons with similar products in the market

Ceiling‑mounted quad PIR detectors are commonly used where wide area coverage and discretion are priorities. Compared with alternative ceiling PIRs, the Octopus DQ stands out for a combination of features:

• Blue Wave DSP vs. basic analog processing: Some competing units still rely on simpler analog circuitry or older signal processing methods. Blue Wave’s digital temperature compensation and IFT typically deliver better false alarm resistance in environments with thermal fluctuation or electrical interference.
• Selectable pulse count: While many ceiling PIRs offer basic sensitivity settings, the Octopus DQ’s selectable pulse count provides installers with more granular control over detection thresholds and robustness, helping tailor performance to specific site conditions.
• Installation ergonomics: The single‑screw mounting and clip‑in PCB speed up commissioning compared with detectors that require multi‑screw mounting or fiddly wiring platforms. For installers managing many devices, small efficiencies add up.
• Certification and warranty: Grade 2 certification and a 5‑year warranty make the Octopus DQ competitive for commercial bids where recognised standards and long‑term support matter.

There are higher‑grade ceiling detectors (Grade 3/4) and devices that incorporate dual‑technology sensing (PIR plus microwave), which can be preferable in extremely challenging environments or where higher security grades are mandated. However, for most retail, office and residential common‑area deployments the Octopus DQ offers an excellent balance of performance, false alarm immunity and cost‑effectiveness.

Conclusion: Why the Octopus DQ is a strong choice

The Pyronix Octopus DQ (OCTOPUSDQ) is a compact, capable and installer‑friendly ceiling 360° quad PIR detector that suits a wide range of commercial and residential applications. Its combination of quad‑interlocking sensors, Blue Wave digital signal processing with temperature compensation and IFT, selectable pulse counts, and practical mounting features delivers reliable volumetric detection with low false alarm susceptibility.

For projects that require unobtrusive overhead coverage—shops, corridors, storerooms, communal areas and similar spaces—the Octopus DQ provides an excellent balance of performance, compliance (EN standards and PD6662 listing) and total cost of ownership. With straightforward panel integration, tamper protection and a 5‑year warranty, it is a sensible choice for installers and system designers seeking proven ceiling‑mount PIR performance at Grade 2 security levels.

Always follow the manufacturer’s installation and commissioning guidelines and involve competent personnel to ensure optimal placement, height and configuration for reliable day‑to‑day operation.
