Introduction to the Texecom Impaq SC‑W (GJA‑0014) and its key features
The Texecom Impaq SC‑W (model GJA‑0014) is a compact wireless combined shock (vibration) detector with an integrated magnetic contact designed for perimeter and window protection. Built around Texecom’s VIBER™ 3‑axis accelerometer and advanced digital signal processing, the unit is intended for professional alarm installations where reliable detection and reduced component count matter. Key features include Ricochet wireless mesh signalling, five selectable sensitivity levels, two additional wired inputs, LED‑assisted commissioning and a typical battery life of around three years. Certified to Grade 2 standards, the device targets domestic and light commercial use where dependable, tamper‑aware perimeter protection is required.
- VIBER™ 3‑axis accelerometer technology providing improved detection and flexible mounting options
- Combined shock sensor and magnetic contact in a single housing to reduce installation complexity and visual clutter
- Ricochet wireless mesh for improved range and network resilience compared with single‑hop radios
- Five digital sensitivity settings with DSP to reduce false alarms while retaining detection performance
- Additional wired inputs and tamper monitoring for extended system integration
Detailed specifications and benefits

- Warranty: 2 years replacement (battery excluded)
- Reduced components and faster installs— combining shock and magnetic contact reduces parts and cable runs, making installations neater and quicker, particularly on windows and frameless glass.
- Improved detection with lower false alarms— the VIBER™ 3‑axis accelerometer plus DSP gives good discrimination between genuine impact/vibration events and benign disturbances such as wind or traffic vibration, helping to reduce unnecessary callouts.
- Flexible integration— two additional wired inputs provide options for roller‑shutter detectors, auxiliary contacts or using Terminal 2 as an additional tamper input.
- Network reliability— Ricochet mesh signalling boosts effective wireless range and provides multiple communication paths to the panel, enhancing resilience in challenging RF environments.
- Installer friendly— LED‑assisted commissioning and walk‑test modes help set appropriate sensitivity and ensure correct mounting points and coverage during setup.
Use cases and scenarios where the Impaq SC‑W excels
The Impaq SC‑W is particularly well suited to scenarios where perimeter and window protection must be robust but visually discreet, and where installers want to minimise component count and installation time. Typical use cases include:
- Residential window protection— ideal for bay and casement windows, where a combined shock/contact unit hides within a small footprint and secures both vibration and magnet open/close events.
- Ground‑floor glazed units— for domestic front and back windows or small‑office glazed fronts where an effective localised shock detection radius (surface dependent) is required.
- Secondary perimeter points— outbuildings, garages and conservatories where Grade 2 intrusion performance is required without expensive hardwired infrastructure.
- Roller shutters and auxiliary contacts— use the wired inputs to tie in shutter position sensors or other local contacts without needing additional radio devices.
- Retrofit projects— battery operation and wireless mesh communications mean the unit works well in retrofit installations where running cables is impractical or costly.
Recommended detection radii are surface dependent — approximately 1 m for wood and framed glass, and around 0.5 m for concrete. These guidance values highlight why correct mounting and sensitivity selection are important during commissioning.
Comparisons with similar products on the market
Combined shock and contact detectors are a common category in the intruder alarm market. Where the Impaq SC‑W stands out is the combination of VIBER™ 3‑axis accelerometer technology, DSP‑based false alarm rejection, and Ricochet mesh network support. Key comparison points:
- Detection technology: Many competitors use single‑axis or simpler piezo sensors for shock detection. The VIBER™ 3‑axis solution offers improved sensitivity and mounting flexibility, particularly on complex surfaces.
- Wireless reliability: Ricochet mesh is a robust mesh protocol that increases hop‑based range and redundancy. Some alternative devices use point‑to‑point radios that can be more sensitive to range limitations or single path failures.
- Installation flexibility: The integrated magnet plus extra wired inputs reduce the number of separate devices required compared with setups that need dedicated contact sensors plus separate shock sensors.
- Standards and certification: The Impaq SC‑W’s Grade 2 certification and PD6662 compliance make it competitive for domestic and light commercial installations; always check the appropriate grade of alternative devices relative to your requirement.
While some higher‑end models aimed at Grade 3 applications will offer greater environmental tolerance or more advanced multi‑sensor fusion, they are typically more expensive and may be over‑specified for many residential or small commercial projects — making the Impaq SC‑W a well‑balanced option.
Customer feedback and installer impressions
Direct customer testimonials for a specific SKU are not provided here, but typical feedback from professional installers and integrators using the Impaq SC family tends to highlight a few recurring themes:
- Ease of installation— installers appreciate the small footprint, combined function and LED‑assisted commissioning which reduces setup time and on‑site tuning.
- Reliable wireless performance— Ricochet mesh often receives positive comments for improving communication reliability in buildings with challenging RF environments.
- Good false‑alarm performance— the DSP and selectable sensitivity help reduce nuisance alarms when mounted and tuned correctly.
- Battery life— typical multi‑year battery life aligns with expectations for wireless sensors, reducing maintenance frequency.
For prospective buyers it is sensible to ask installers for site‑specific references or case studies, and to verify how sensitivity settings and mounting choices are applied in practice on different surfaces.
