Wireless Ceiling PIR Detector, 12 m 360°, AX‑Pro, DS‑PDCL12‑EG2‑WE

Introduction to the DS‑PDCL12‑EG2‑WE Wireless Ceiling PIR Detector

DS‑PDCL12‑EG2‑WE — Wireless ceiling-mounted 360° PIR detector (AX‑Pro compatible)is a purpose-built intrusion detector designed for indoor ceiling installation where complete overhead coverage is required. With a 12 m detection radius, 172 detection zones and 360° detection coverage, it is tailored to protect rooms, corridors and open-plan areas from unauthorised entry. The unit combines modern digital signal processing, sealed optics and secure two-way wireless transmission to deliver dependable detection while minimising nuisance alarms.

Key features at a glance

• 360° passive infrared (PIR) detection with a 12 m radius and 172 detection zones for full overhead coverage.
• SEC digital signal processing and sealed optics to reduce false alarms from dust, insects and environmental changes.
• Tri‑X two‑way wireless (868 MHz) with AES‑128 encryption, frequency hopping and supervised transmission (manufacturer quoted free-space range up to 1.6 km).
• Battery powered (1 × CR123A, 3 V) with expected standby life up to 5 years under test conditions.
• Multiple enrolment methods (power-up, remote ID, QR code) and remote configuration when paired with compatible AX‑Pro hubs and apps.
• Front and rear tamper protection, LED alarm indicator, signal strength and temperature indicators.

Detailed specifications and benefits

• Detection method:Passive Infrared (PIR) provides proven, energy-efficient motion detection by sensing changes in infrared energy.
• Range and coverage:12 m detection radius with 360° coverage and 172 detection zones — ideal for rooms with a central ceiling mount where a wide, even detection pattern is required.
• Detectable speed:Designed to detect moving targets in the range of 0.3–2 m/s, covering typical human motion including walking and running.
• Sensitivity and false alarm resistance:Auto/Low sensitivity settings, a white light filter (6,500 lux) and a dedicated creep zone help tune the detector to reduce false alarms from environmental light or slow-moving objects near the floor.

• SEC digital signal processing:Advanced processing evaluates PIR signals to distinguish genuine motion from spurious disturbances, improving reliability in indoor environments.
• Sealed optics:The sealed optical chamber limits dust and insect ingress — common causes of phantom alarms — improving long-term stability and reducing maintenance visits.

• Tri‑X wireless, 868 MHz:Two-way RF communications provide bidirectional health and event reporting with supervised links to compatible hubs.
• Security:AES‑128 encryption and frequency hopping help protect transmissions against eavesdropping and jamming attempts that can compromise less secure wireless devices.
• Range:Manufacturer quotes up to 1.6 km free-space range — in practice this translates to strong building penetration and reliable links when installed with standard professional practices and site surveys.

• Battery powered:Single CR123A cell keeps the detector compact and simple to install without the need for fixed mains wiring.
• Battery life:Up to approximately 5 years standby life under manufacturer test conditions, minimising routine maintenance and battery replacement visits.

• Enrolment methods:Power-up, remote ID and QR code options enable flexible provisioning at the panel or remotely via compatible AX‑Pro hubs and apps.
• Mounting height:Recommended at 2.4–4 m ceiling heights to achieve the intended 12 m radius.
• Tamper protection:Front and rear tamper switches provide anti-tamper alerts if the unit is removed or interfered with.
• Indicators:LED alarm indicator plus signal strength and temperature indicators help commissioning and ongoing diagnostics.

Use cases and scenarios where the detector excels

For larger rooms with a central ceiling position, the DS‑PDCL12‑EG2‑WE’s 360° coverage eliminates blind spots and reduces the need for multiple wall-mounted detectors. The 12 m radius and well-defined detection zones allow a single sensor to monitor moderate-sized stores, showrooms or open-plan office areas effectively.

Where corridors meet or a central ceiling location provides line-of-sight to multiple approaches, a ceiling-mounted 360° PIR offers a convenient way to detect movement from any direction without complex placement planning.

Shared indoor spaces such as apartment building lobbies, laundry rooms and elevator lobbies benefit from a ceiling PIR that is unobtrusive, vandal-resistant and easy to maintain. Battery operation avoids potentially disruptive wiring work in finished interiors.

In retrofit projects where running mains wiring is impractical or costly, the wireless CR123A-powered detector is fast to deploy and simple to commission via QR or remote enrolment methods. Its sealed optics and long battery life make it suitable for infrequently accessed utility rooms and storage areas as well.

How it compares with similar products on the market

Understanding where the DS‑PDCL12‑EG2‑WE sits compared to other detectors helps installers and system designers choose the right device for the job:

• Ceiling 360° PIR vs wall-mounted PIR:Ceiling 360° detectors provide central coverage and eliminate many wall-mounted blind spots, but wall PIRs can be better for long, narrow spaces where directional coverage is needed. The DS‑PDCL12‑EG2‑WE is ideal when you need radial coverage from a central point.
• Wireless protocol strengths:The Tri‑X 868 MHz two‑way RF with AES‑128 and frequency hopping offers stronger range and security compared to legacy 433 MHz one‑way devices or consumer-level Wi‑Fi and Zigbee solutions. For professional intrusion systems where supervision and encryption matter, this device offers clear advantages.
• Sealed optics and DSP:The combination of sealed optics and SEC digital signal processing reduces false alarms compared to basic PIR models that lack environmental protection or advanced filtering. This can translate into fewer service calls and greater end-user satisfaction.
• Battery life and form factor:CR123A-powered detectors are common in professional kits. The quoted ~5-year standby life is competitive for devices with frequent supervision reporting; however, real-world life depends on reporting intervals and environmental factors.

Installation tips and best practices

• Install at the recommended ceiling height (2.4–4 m) for optimal coverage and to match the 12 m detection radius.
• Perform a wireless site survey prior to final placement to verify link quality to the AX‑Pro hub, taking into account building materials and potential interference sources.
• Use the onboard signal strength indicator and temperature readout during commissioning to confirm reliable operation and appropriate environmental conditions.
• Follow the datasheet for tamper wiring, recommended orientation and maintenance to ensure compliance with local alarm standards and warranty terms.
