Detailed specifications and benefits
The CombiProtect S Jeweller brings together a well‑tuned set of specifications that address common trade‑offs in intrusion detection: coverage, false alarm reduction, battery life, and secure communications.
- Motion range: Up to 12 m with an 88.5 horizontal field of view. Recommended mounting height is around 2.4 m to balance coverage and avoid false triggers from small animals or drafts.
- Motion intelligence: SmartDetect compensates for temperature variations and offers three sensitivity levels, improving reliability in spaces with changing ambient conditions.
- Glass‑break sensing: The electret microphone detects glass fractures up to 9 m away and covers a wide 180 horizontal arc. DualTone analysis uses two frequency bands to verify true glass break events and reduce spurious activations from door slams or other noises.
- Pet immunity: Configurable to ignore animals up to 20 kg and 50 cm in height when positioned correctly, making it suitable for many family homes while maintaining high detection for human intruders.
- Battery: Ships with a pre‑installed Panasonic CR123A (approximately 1,600 mAh) at 3 V.
- Battery life: Typical service life is up to 5 years, depending on polling intervals, alarm frequency and environmental conditions. Low battery and end‑of‑life warnings are pushed to the Ajax app.
- Jeweller protocol: Encrypted two‑way communication with anti‑jamming measures and device authentication. Open‑space range can reach up to ~1,200 m (actual range varies by hub, building materials and environment).
- Tamper protection: The S model includes lid tamper protection (two tampers) and a SmartBracket holding screw for secure, tamper‑resistant mounting—important for commercial deployments or exposed domestic installations.
- Form factor: Compact dimensions (110 × 65 × 50 mm) and an IP50 rating allow flexible placement inside buildings without bulky hardware.
The device is intended for professional systems; installers should follow the full datasheet and user manual for certification marks (CE/UKCA where applicable), wiring and mounting guidance. Correct height and orientation are essential for pet immunity and reliable coverage.

Use cases and scenarios where the CombiProtect S excels
Combining motion and glass‑break sensing in a single enclosure reduces hardware count, wiring complexity and installation time. Typical scenarios where this design provides clear benefits include:
- Residential installations: In homes with windows that are potential points of entry, the CombiProtect S covers both room motion and glass break events without adding two separate devices. Its pet‑immunity mode helps avoid nuisance alarms in family homes.
- Small businesses and retail: Retail shops, offices and front‑of‑store areas benefit from combined detection near display windows. DualSensor coverage decreases the probability of missed events and lowers maintenance overhead.
- Remote or multi‑site deployments: For managed security providers or installers equipping multiple properties, shipping and maintaining one combined device per room cuts inventory complexity and speeds up replacement tasks.
- Accredited installations: The S (Superior) editions PRO features and improved tamper options suit professional, accredited installations that require traceability, advanced configuration and a more discreet matte finish.
- Areas with variable temperatures: SmartDetects temperature compensation helps maintain consistent motion sensitivity in spaces that warm or cool significantly throughout the day.
How it compares with similar products
There are three common approaches in the market: combined detectors (like the CombiProtect S), standalone motion sensors plus separate glass‑break microphones, and lower‑cost multi‑sensors with less sophisticated signal processing. The CombiProtect S stands out in several ways:
- Versus separate sensors: Pairing a motion detector and a glass‑break microphone in one device reduces the number of enclosures and associated mounting points. This lowers installation time and cost while simplifying maintenance and battery management.
- Versus budget combo sensors: Low‑cost combos often use simpler algorithms and lower‑quality microphones, leading to higher false alarm rates. The CombiProtect Ss SmartDetect and DualTone processing are designed to reduce false positives without sacrificing sensitivity.
- Versus wired solutions: Wireless installation is faster and less disruptive, especially in retrofit scenarios. When paired with a robust hub using Ajaxs Jeweller protocol, wireless performance approaches wired reliability for many deployments, though installers should always validate radio coverage on site.
- Versus other professional combos: The S models extra tamper protections and PRO‑channel features make it a better fit for accredited installations compared with entry‑level variants. Battery life and pre‑installed Panasonic cells deliver longer maintenance intervals than some rival wireless combos with smaller batteries.
What customers and installers say
While individual experiences vary by environment and installer practice, feedback from professional installers and end users typically highlights the following themes:
- Ease of installation: Installers appreciate having both motion and glass‑break coverage in one device—it reduces the number of holes drilled and the time on site.
- Lower maintenance: Long battery life and centralized remote configuration via the Ajax apps reduce routine maintenance trips, especially across multiple properties.
- Fewer false alarms: Many users note improved alarm accuracy compared with older combo sensors, attributing this to the DualTone and SmartDetect algorithms; proper placement and sensitivity tuning are still essential.
- Professional finish: The Superior editions matte appearance and additional tamper measures are seen as a positive for commercial installs where discreet and robust hardware is required.
Note: These observations are representative of typical installer and user feedback for professional-grade combined detectors; for verified testimonials, check with accredited Ajax partners or vendor listings.
