Introduction: Meet the Texecom Premier Elite Micro Contact‑W (GHA‑0002)
The Texecom Premier Elite Micro Contact‑W (GHA‑0002) in anthracite is a purpose‑built, ultra‑compact wireless magnetic contact designed for concealed perimeter detection on windows and doors. Combining a tiny form factor with Texecoms Ricochet mesh radio technology and Grade 2 intrusion certification (EN5013126), it targets installers and end users who need a low‑profile, reliable contact that blends into uPVC, wooden or aluminium frames without compromising detection performance.
Key features include its micro size for concealed installation, Ricochet mesh repeater capability to extend and harden wireless range, an included CR2450 battery (typical life around four years), LED‑assisted commissioning feedback and flexible mounting options. Together these make the GHA‑0002 a strong choice for residential and light commercial perimeter security projects.
Detailed specifications and the benefits they deliver
Understanding the technical details helps explain why the Micro Contact‑W performs well in concealed installations and trusted security systems.
The contact measures approximately 57 × 27.5 × 8.2–11.5 mm and weighs about 25 g, making it one of the smallest wireless contacts designed to fit inside narrow window and door frames. Its small footprint allows installers to conceal the unit entirely within uPVC or slim timber/aluminium profiles, preserving appearance and reducing the risk of tampering or accidental damage.
Mounting is flexible: use adhesive for rapid, non‑invasive installations or screw fixing for a more permanent fit. The device also supports surface mount where frame cavities are not available, giving installers options to match the site conditions.
The Micro Contact‑W is powered by a single CR2450 battery (included) at 3 V. Typical battery life is approximately four years under normal use. Quiescent current is very low (around 10 µA), with short bursts of higher draw (up to ~12 mA) while transmitting. A low voltage threshold at approximately 2.80 V helps the system report battery status reliably so replacement can be planned before signal loss.
This model operates on the 868 MHz band with Ricochet mesh networking. RF output is modest (max ~10 mW) and transmissions have a duty cycle under 1%, which conserves battery while meeting regulatory limits. The receiver uses Listen Before Talk (LBT) techniques and is Category 1 Class 2 rated, improving coexistence in busy RF environments.
The Ricochet mesh capability is a major benefit: devices act as repeaters to relay messages, effectively increasing usable range and resilience in larger properties or in buildings with RF obstacles. This reduces dead spots and simplifies planning for installers by allowing devices to form a self‑healing network.
Operating reliably across typical indoor humidity ranges (0–95% non‑condensing), the unit is EN50131‑2‑6 Grade 2 certified for intrusion applications. This certification means it meets commonly required standards for residential and light commercial alarm systems, giving specifiers and installers confidence in its suitability for Grade 2 installations.
Practical benefits for installers and end users
- Discreet aesthetics:hidden installation keeps sight lines clean and reduces vandalism or tampering risk.
- Robust wireless reliability:Ricochet mesh extends range and provides redundancy so single point failures or isolated RF issues are less likely to cause loss of coverage.
- Low maintenance:long battery life and clear low‑voltage reporting reduce service visits and unexpected outages.
- Fast commissioning:LED feedback during setup simplifies positioning and testing, saving installer time on site.
- Grade 2 compliance:accepted for many domestic and light commercial alarm systems where certified components are required.
Use cases and scenarios where the Micro Contact‑W excels
The GHA‑0002 is especially well suited to situations where concealment, aesthetics and reliable wireless performance are priorities:
- New build or retrofit residential properties:Fit inside slim uPVC frames to preserve window appearance and meet homeowner expectations for invisible security hardware.
- Listed buildings or sensitive interiors:Where surface hardware is undesirable, the micro contact allows secure monitoring without visible changes to joinery.
- Multi‑point perimeter coverage:In homes or small commercial premises with multiple windows and doors, Ricochet mesh makes it straightforward to deploy many contacts without worrying about range limitations.
- Rental or managed properties:Adhesive mounting lets property managers fit or move sensors without damage, while long battery life reduces ongoing service costs.
- Commercial Grade 2 systems:For light commercial premises requiring certified components, this contact integrates into systems where EN50131‑2‑6 compliance is requested.
How it compares with similar products
Compared with traditional surface‑mounted magnetic contacts, the Micro Contact‑W stands out for its concealment, low visual impact and modern wireless capability. Surface units are larger and more visible, making them easier to tamper with or dislodge and less attractive for high‑end installations.
Against other small wireless contacts on the market, the differentiators for the GHA‑0002 are the Ricochet mesh networking and Grade 2 certification. Some micro contacts from other manufacturers may offer a similar small profile, but if they lack mesh repeater capability, installers might encounter more dead spots or need additional repeaters. Conversely, devices with larger batteries may achieve longer life but at the cost of a bigger form factor unsuitable for concealed fitment.
For installers choosing between brands, the practical tradeoffs are concealment versus battery capacity, mesh capability versus added system complexity, and certification level. The Micro Contact‑W balances these well: it preserves a tiny footprint while delivering mesh redundancy and an industry‑recognized certification level for many typical alarm applications.
Customer feedback and installer impressions
Publicly available consumer reviews specific to this exact model are limited, which is common for component items that are typically purchased and installed by professional alarm contractors rather than end users directly. However, installer feedback in the field commonly highlights a few recurring positives:
- Installers appreciate the compact dimensions, which allow truly concealed installation in frames that other micro contacts cannot fit into.
- Ricochets repeater characteristics are frequently cited as simplifying wireless system design, with fewer dedicated repeaters needed and fewer RF issues to troubleshoot.
- Long battery life and clear LED‑assisted commissioning are noted as real time savers during multi‑point installs.
Because the product is normally deployed by professionals, much of the reputation is established through trade channels and installer recommendations rather than consumer review sites. For prospective buyers, asking trusted installers for prior site examples or references is a good way to validate suitability for a specific project.
Conclusion: Why the Texecom Premier Elite Micro Contact‑W is a strong choice
The Texecom Premier Elite Micro Contact‑W (GHA‑0002) is a focused solution for anyone specifying concealed perimeter detection where appearance, reliability and certification matter. Its tiny form factor enables invisible installation inside narrow frames, while Ricochet mesh networking and Grade 2 certification deliver the robustness and standards compliance expected in many residential and light commercial alarm systems.
For installers, the benefits are practical: fewer RF planning headaches, straightforward commissioning with LED feedback, flexible mounting choices and a battery life that keeps maintenance demands low. For homeowners and property managers, the advantage is a discreet security system that preserves aesthetics without sacrificing coverage.
In short, when you need a small, professional‑grade magnetic contact that integrates into a modern wireless alarm ecosystem, the GHA‑0002 offers a compelling balance of concealment, wireless resilience and certified performance.
