Designed to monitor narrow zones such as perimeters, windows, gates, doors, and arches, it provides focused protection while minimizing false alarms. Operates as part of the Ajax system via the Jeweller secure radio protocol. Ajax Systems+2Ajax Systems Support+2

Key Features & Capabilities

Technical Specifications

Use Cases & Installation Best Practices

• Ideal for perimeter / narrow-zone protection: windows, facades, gates, archways, paths; these are narrow zones where full-coverage motion detectors may be overkill or prone to false alarms.

• Avoid blind spots: Enable “near zone detection” especially in doorways or near windows; position correctly so the detection beams cross the intended path. Mount at recommended heights (≈ 0.8-1.3 m for doors/arches, ≈ 0.5-0.6 m when protecting windows) depending on what you’re protecting. Ajax Systems Support+1

• Configure each side separately: Each of the two “curtains” (left/right) can have different detection distances, disable one side if not needed, direction tilt, etc., to reduce false triggers (e.g. vegetation, moving objects).

• Use anti-masking & tamper protection: Ensure masking sensors are clear, lens not obstructed; mounting panel (SmartBracket) firmly in place.

• Wireless signal planning: Ensure good signal strength to hub or use ReX extenders if distance or obstacles exist.

Summary

The Ajax DualCurtain Outdoor Jeweller is a specialized, high-precision outdoor curtain-style motion detector offering:

• Bidirectional curtain coverage (left & right sides),

• Long range (up to ~30 m combined),

• Strong false alarm prevention (pet immunity, anti-masking),

• Reliable wireless communication (Jeweller, up to ~1,700 m open),

• Robust outdoor-rated housing (IP54, wide temp range).

Excellent choice where a narrow, focused detection strip is required around sensitive outdoor points or perimeters, while still maintaining high reliability and low false alarms.

Wireless indoor motion detector with built-in camera for photo-verification. Part of the Ajax security ecosystem, combining reliable motion detection, pet immunity, and visual confirmation of alarms to reduce false alarms and speed up response. ajax.systems+2Ajax Systems Support+2

Key Features

• False Alarm Suppression: SmartDetect algorithm and temperature compensation help reduce spurious triggers due to heat sources, drafts, etc. ajax.systems+1

• Low Light & IR Backlight: For photo capture in darkness, IR backlight provides visibility even when ambient light is low. ajax.systems+1

• Tamper & Security Features: Contains a tamper switch to detect removal from mounting panel or attempts at physical interference. Also uses device authentication, encrypted communication, and frequency-hopping to protect against spoofing / jamming. ajax.systems+1

Applications & Benefits

• Provides visual confirmation of motion alarms, helping users and monitoring services verify whether an alarm is real before dispatching personnel. Ajax Systems Support+1

• Especially useful in rooms with pets, or where false alarms are common (e.g. kitchens, near windows), because of pet immunity and adjustable sensitivity.

• Good for nighttime or low light areas thanks to IR backlight enabling photo verification in darkness.

• Ideal for indoor use, such as homes, offices, shops, corridors, entryways.

Wireless glass-break detector with electret microphone operating on Ajax’s secure Jeweller radio protocol. Designed for indoor protection of windows, glass doors, showcases and other vulnerable glass surfaces. Detects the characteristic sound patterns of glass breakage, filters out false alarms, and integrates smoothly with Ajax security systems. ajax.systems+2ajax.systems+2

Key Features

• DualTone detection algorithm — requires detection of both a low-frequency impact (dull sound) and a high-frequency ringing (glass fragments) within ~1.5 seconds to trigger alarm. Cuts down false alarms from traffic, dogs barking, etc. ajax.systems+1

• Detection distance & angle — glass break detection up to 9 meters; ~180° horizontal coverage. ajax.systems+2Megateh+2

• Adjustable sensitivity — three levels via Ajax app for adaptation to environment. ajax.systems+1

• External wired NC input — terminals available to connect a third-party normally-closed (NC) detector (e.g. another glass break, motion, vibration, or opening detector). ajax.systems+1

• Long battery life — pre-installed CR123A battery giving up to ~7 years of autonomous operation under typical use. Low battery and status updates via app. ajax.systems+2ajax.systems+2

• Wireless range — up to ~1,000-1,700 m in open space between the GlassProtect and Ajax Hub (or range extender), depending on environment. ajax.systems+2Megateh+2

• Tamper protection — tamper switch activates when detector is detached from its SmartBracket mounting panel or cover is opened. Alerts sent. ajax.systems+1

• False-alarm resistance — DualTone algorithm plus adjustable sensitivity help ignore non-glass break noises. Note: the detector does not detect breakage of glass covered with certain films (shockproof, sunscreen, decorative, etc.) without additional appropriate sensors. ajax.systems+2ajax.systems+2

Technical Specifications

Applications & Suitable Use

• Ideal for securing glass windows, doors, display cases, and other glass panels in homes, offices, retail stores, schools, etc.

• Use in areas where false alarms are a concern (near busy roads, pets, etc.), since detector filters non-glass break noises.

• Best in indoor, sheltered locations. Avoid installing outdoors or where the glass is heavily covered with masking films unless a detector with shock/tilt is used.

• Works well in systems where quick verification is required: once glass break is detected, hub triggers alarms, notifications, and connected sirens, or runs automation scenarios (lighting, camera recording etc.).

A premium wired glass-break detector in the Ajax Superior / Fibra line, designed for indoor security installations that require reliable, false-alarm-resistant detection over long wired distances. Only accredited partners may install, configure, or maintain these devices. Ajax Systems Support+2ajax.systems+2

Technical Specifications

Applications & Use Cases

• Glass-front windows, display cases, shopfronts, and other glass surfaces where fast detection of breakage is needed.

• High-security locations with risk of attempted smashing, vandalism, or break-in via glass.

• Facilities that require wired reliability and sturdy, tamper-resistant hardware for critical points of entry.

• Integrations where both primary event detection (glass break) and auxiliary detection via external wired NC contacts are beneficial (e.g. backing sensors).
