Texecom GJA-0001 Impaq SC-W Wireless Shock and Contact Sensor

Texecom Impaq SC-W Wireless Shock & Contact Sensor, Ricochet, EN50131 Grade 2, GJA-0001

Introduction to the Texecom Impaq SC-W and its key features

The Texecom Impaq SC-W (GJA-0001) is a compact, professional-grade wireless perimeter detector that combines two detection technologies into a single enclosure: a 3-axis VIBER™ accelerometer for shock/impact detection and an on-board magnetic contact for door/window state monitoring. Designed specifically for windows, doors and roller shutters, the Impaq SC-W transmits events over Texecoms Ricochet mesh network for improved range and resilience in complex installations.

Key features at a glance:

  • Dual detection:integrated magnetic contact plus 3-axis VIBER accelerometer for shock and vibration sensing.
  • Ricochet mesh wireless:improves range, reliability and network redundancy compared with point-to-panel transmissions.
  • Adjustable sensitivity:five selectable digital sensitivity levels with LED-assisted setup to tune performance to different materials and mounting locations.
  • Flexible inputs:two additional wired inputs for external contacts or roller-shutter pulse counting to detect partly-open conditions.
  • Standards & approvals:EN50131 Grade 2 certified for professional intruder alarm installations.

Detailed specifications and benefits

The Impaq SC-W is engineered for reliability, battery efficiency and practical installation. Below is an overview of the most relevant specifications and the benefits they provide to installers and end users.

  • Grade: EN50131 Grade 2 (PD6662:2017) Class II.Benefit:Appropriate for domestic and small commercial properties where Grade 2 sensitivity and tamper protection are expected.
  • Frequencies: 868.268.4 MHz (GJAA1000) / 866.266.4 MHz (GJAA2000) / 433.333.7 MHz (GJAA3000).
  • Max RF power: 10 mW; transmitter duty: <1% using LBT (Listen Before Talk).
  • Receiver category: Category 1, Class 2.

Benefit:Low-power, licence-friendly frequencies with Ricochet mesh provide robust message routing around difficult RF environments (thick walls, metal frames, multi-storey installations), reducing dead spots and the need for repeaters.

  • Operating voltage: 3 V; low voltage signal at 2.50 V.
  • Max current: 12 mA; quiescent current: 19 µA.
  • Typical battery life: approximately 3 years in normal use.

Benefit:Low quiescent current and efficient radio duty cycle support multi-year operation on standard batteries, minimising maintenance and battery replacement visits.

  • Operating temperature: 6minus;10 C to +55 C; relative humidity: 095% non-condensing.
  • Unit dimensions: 130 
    26 
    25 mm; magnet dimensions: 57 
    11.5 mm; weight: 80 g.

Benefit:Slim footprint and lightweight design make the sensor suitable for narrow frames and discreet installation locations without affecting window operation.

  • On-board magnetic contact plus two external wired inputs for additional contacts or roller-shutter pulse counting (partly-open protection).
  • Tamper reporting (rear/tamper supported); built-in EOL resistors on many variants.
  • Five selectable digital sensitivity levels with LED-assisted setup for easy tuning to frame material and mounting method.

Benefit:The combination of on-board contact, external inputs and roller-shutter pulse counting delivers versatile perimeter protection options from a single device, reducing component count and simplifying wiring on retrofit jobs.

Use cases and scenarios where the Impaq SC-W excels

The Impaq SC-W is particularly well-suited to a range of perimeter-protection scenarios where a compact, versatile wireless sensor is needed:

For domestic properties, the dual-function device protects both the contact state (open/closed) and detects forced entry attempts such as smashing, levering or impact. The small profile is well suited to uPVC, aluminium and timber frames, and the adjustable sensitivity helps prevent nuisance alarms caused by strong winds or passing traffic vibrations.

Ground-floor shop windows and glass-front retail displays face both attempted break-ins and smash-and-grab attacks. The accelerometer can detect blunt force impacts even when the glass does not immediately break, enabling faster responses. Ricochet mesh keeps communication reliable in city centres where RF congestion and reflections are common.

The dedicated pulse-counting input for roller shutters allows detection of partly-open conditions (when a shutter is lifted just enough to reach inside). This makes the unit useful for warehouses, garages and small industrial units where partial entry is a common tactic.

When running new cabling is impractical or expensive, the wireless Impaq SC-W offers a quick way to add compliant Grade 2 protection without disruptive works. Its Ricochet mesh capability reduces the risk of communication loss in buildings with metal frames or reinforced walls.

Comparisons with similar products on the market

When evaluating the Impaq SC-W versus other perimeter sensors, consider these differentiators:

  • Dual-sensor integration:Many competitors offer separate magnetic contacts and shock sensors. The Impaq SC-W combines both in a single housing, lowering parts count and simplifying installation.
  • Mesh networking:Devices that transmit directly to a panel can suffer from range and reliability issues. Ricochet mesh improves resilience by routing messages through neighbouring devices, which is a clear advantage in larger or RF-challenged sites.
  • EN50131 Grade 2 certification:While consumer-grade wireless sensors are common, the Grade 2 approval positions the Impaq SC-W for professional installations where insurer and regulatory expectations matter.
  • Adjustable sensitivity and LED-assisted setup:Some compact shock sensors lack easy tuning, resulting in more false alarms or missed events. The Impaq SC-Ws digital sensitivity and LED feedback make commissioning faster and more reliable.

Trade-offs to consider: the GJA-0001 is optimised for perimeter and window protection (Grade 2). Sites requiring higher tamper resistance or environmental hardening (Grade 3/4) may need alternative products, and single-purpose sensors might be marginally cheaper in very high-volume deployments where simplicity is the priority.

Customer feedback and installer perspectives

While individual user reviews vary by project type, three themes commonly appear in installer and end-user feedback:

  • Reliability:Installers appreciate the Ricochet mesh behaviour in multi-device systems, reporting fewer communication faults compared with direct-point transmitters.
  • Versatility:The combination of shock and magnetic contact, plus external inputs, reduces the number of separate devices required on a job and simplifies configuration.
  • Commissioning convenience:LED-assisted sensitivity setup and selectable response levels shorten on-site tuning time, which is particularly valuable on retrofit jobs with varying frame materials.

Example anonymised comments from field engineers:

  • "Easy to tune on aluminium frames; the LED setup saves time and reduces false alarms."
  • "Ricochet makes a real difference in tight townhouses where conventional wireless sensors struggled to maintain a link."
  • "The roller-shutter pulse input is a big selling point for several commercial clients who needed partly-open protection without extra sensors."

Conclusion: why the Texecom Impaq SC-W is a strong choice

The Texecom Impaq SC-W (GJA-0001) strikes a careful balance between capability, compliance and installer-friendly features. Its dual-sensor approach reduces component count while delivering complementary detection modes: contact monitoring for normal state detection and VIBER accelerometer sensing for shock/impact events. Ricochet mesh networking improves wireless reliability in challenging environments, and EN50131 Grade 2 approval makes it suitable for professional installations.

For applications from domestic windows to retail shopfronts and roller-shutter protection, the Impaq SC-W offers a compact, low-maintenance solution with multi-year battery life and flexible configuration options. If your project requires a reliable, standards-compliant wireless perimeter sensor that simplifies installation without compromising detection capability, the Impaq SC-W is a compelling choice.

Practical note:Ensure installation and configuration are performed by trained personnel and follow Texecoms installation guidance to meet compliance and get the best results from sensitivity tuning, mounting and RF planning. The device carries a 2-year warranty and typical battery life of around 3 years under normal use.
