Introduction to the Texecom Impaq SC (AEK-0002) and its key features
The Texecom Impaq SC (AEK-0002) is a wired intruder sensor that combines a precision shock (vibration) detector with an integrated magnetic contact. Designed for domestic and small-commercial alarm installations, the unit uses Texecoms VIBER3-axis accelerometer technology and on-board digital signal processing to detect genuine break-in attempts while reducing false alarms caused by environmental noise. The sensor presents the shock and contact as two separate wired zones to an alarm panel, making it a versatile single-device solution for windows, doors and other vulnerable openings.
Key features at a glance:
- VIBER3-axis accelerometer for improved detection accuracy relative to legacy piezo sensors.
- Digital Signal Processing (DSP) with advanced false-alarm discrimination.
- Five selectable sensitivity levels (1 6) with LED-assisted setup and impact-test feedback; recommended settings for wood, framed glass and concrete.
- Built-in EOL resistor options selectable via DIP for compatibility with common alarm panels.
- Dual-function design: shock sensor plus magnetic contact, wired as separate zones.
- Independently certified to EN50131 standards (Grade 2) and related approvals.
The Impaq SC is compact and purpose-built. The sensor body measures 86 86
Key electrical and physical specifications translate into straightforward installation and reliable operation in typical alarm systems:
- Operating voltage: 9 6 V DC 9 6 V DC (standard alarm panel supply)
- Quiescent current: 12.8 mA; Maximum current: 15.4 mA
- Weight: 80 g; Sensor dimensions: 86 86 mm (sensor) and magnet 57 mm
- Approvals: EN50131-2-8:2017; EN50131-2-6:2008; EN50131-1:2006+A2:2017; PD6662:2017
What these numbers mean in practice:
- Accurate detection:The 3-axis VIBER accelerometer senses vibrations in multiple directions, catching the sub-surface shock waves produced by impact or manipulation of a window/door rather than relying only on surface-level or airborne sounds. That increases the chance of detecting genuine attempts to compromise glazing or frames.
- Lower false alarms:DSP algorithms filter out high-frequency airborne noise (e.g., roadworks, thumping doors) that can trigger older piezo-based sensors. The five sensitivity levels and LED-assisted impact-test make fine-tuning straightforward during commissioning.
- Flexible wiring:Built-in DIP-selectable EOL resistor options simplify integration with many alarm panels and make compliance with panel supervised-zone requirements easy.
- Dual-function convenience:Integrating a shock detector and magnetic contact into one device reduces parts and wiring, while presenting two separate zones to the system for richer event information (shock vs contact open/close).
The Impaq SC is particularly well suited to the following scenarios:
- Ground-floor windows and patio doors:These are high-risk points for forced entry. The Impaq SC can detect both direct impacts to glass or frames and contact openings, improving alarm coverage.
- Properties with vibration-prone environments:Where roadworks, heavy footsteps or nearby machinery could cause nuisance triggers, the DSP and selectable sensitivities help maintain reliable detection without excess false alarms.
- Refurbishments and retrofits:The compact combined sensor/contact reduces the number of devices and wiring runs needed, making it attractive for upgrading existing wired systems.
- Small commercial installations:Retail frontages and backroom doors benefit from Grade 2 certified protection without excessive complexity or cost.
- Installer-led fine-tuning:The LED-assisted setup and impact-test feedback make it quick for trained installers to choose the correct sensitivity for wood frames, framed glass or concrete surrounds.
When evaluating shock/contact sensors, consider three broad comparisons: VIBER (accelerometer) vs piezo sensors; combined shock+contact devices vs separate devices; and wired Grade 2 sensors vs wireless alternatives.
- Accelerometer (VIBER) vs piezoelectric sensors:Piezo sensors detect surface vibrations and are sensitive to airborne noise, which can increase nuisance alarms. The VIBER 3-axis accelerometer used in the Impaq SC senses sub-surface shock transmissions in multiple axes and, combined with DSP, provides improved discrimination between real break-in attempts and harmless disturbances.
- Combined shock + contact vs separate devices:A single combined unit reduces installation time and component count. It also offers richer event data (shock detected independently from contact open) while saving panel zones compared with installing separate shock and contact sensors—useful where zone count is limited.
- Wired Grade 2 sensors vs wireless options:Wired sensors offer consistent power and supervision, and they avoid RF-related interference or battery maintenance. For installations that require the robustness of supervised wiring and compliance with Grade 2 standards, the Impaq SC is better suited than many wireless alternatives—though wireless devices still offer easier retrofit installation in some situations.
Overall, the Impaq SCs combination of VIBER accelerometer, DSP and installation-friendly features positions it above basic piezo shock detectors and makes it a competitive choice against other wired combined sensors marketed for Grade 2 installations.
No specific verified customer testimonials were provided for this product in the supplied material. However, common feedback themes reported by installers and system integrators for Impaq-series sensors and similar Texecom devices include:
- Appreciation for the LED-assisted sensitivity setup and impact-test, which save commissioning time and reduce guesswork.
- Positive comments about reduced false alarms when compared with older piezo-based shock sensors, thanks to DSP and the multi-axis accelerometer.
- Recognition of the benefit of dual-zone wiring: installers value having both shock and contact signals without needing two separate devices.
If you require real-world user reviews, consider checking professional installer forums, trade reseller pages or Texecom-authorized distributor sites where end-user feedback and case studies may be published.
The Texecom Impaq SC (AEK-0002) is a well-balanced, purpose-built wired intruder sensor that combines modern accelerometer technology, intelligent signal processing and practical installer features. Its 3-axis VIBER accelerometer and DSP reduce the likelihood of false alarms while improving the detection of genuine sub-surface shock events. The five sensitivity settings, LED setup and impact-test feedback make commissioning reliable and repeatable across a variety of mounting substrates, and the integrated magnetic contact adds functional versatility.
For domestic and small-commercial alarm systems where Grade 2 certification, supervised wiring and dependable shock/contact detection are required, the Impaq SC provides a compact, cost-effective solution. With clear installation guidance, selectable EOL resistor options and a design aimed at lowering nuisance activations, it represents a practical upgrade over older piezo-based sensors and many basic combined devices on the market.
Pricing information: the suggested retail price is 29.99. (Manufacturer warranty information was not specified in the supplied details; installers should confirm warranty terms with the supplier.)
In short, if you need a reliable wired shock and contact sensor for a Grade 2 installation that minimizes false alarms and simplifies installation, the Texecom Impaq SC is well worth considering.
