ENSURE everyone is Home Safe with Aspect Link

SOS, True Man Down, Health Check, and more, are all available but Timed Personal Alert (TPA) is a proactive safety feature that automatically triggers an alarm if a check-in timer expires without deactivation. Originally developed by Isle Systems in 2006 for lone workers in rural or remote areas, it serves as a reliable backup to SOS and Man Down alerts, functioning even if a device is powered off, damaged, or out of coverage.

  • Activation: Set timers via SMS, the iOS/Android mobile app, or the web portal (with optional contextual notes).

  • Reminders & Alerts: Users receive a start confirmation and up to four interval reminders—delivered via SMS or spoken voice alerts in the app—before expiration.

  • User Control: Timers can be freely extended or cancelled at any time during the countdown. If unaddressed, the Aspect Link system automatically generates an alert.

INSTANTLY notify people of a Fire Alarm

Connecting your fire alarm system to Aspect Link dramatically improves life safety and emergency management by enabling targeted, multi-sensory response protocols:

  • Accessible Emergency Notifications: Automatically alerts individuals who are deaf or hard of hearing when an alarm activates, and provides clear information to visually impaired occupants.

  • Building-Wide Situational Awareness: Instantly informs both fire marshals and general personnel of the precise location of the fire, eliminating confusion during an evacuation.

  • Automated Route Guidance: Immediately distributes tailored exit instructions to occupants, directing them on the safest evacuation routes.

NO LIMITS - Two-way-Radio - Atlas PTT

Atlas PTT transforms standard smart devices and Android phones into powerful Push-to-Talk over Cellular (PoC) radios—delivering instant, secure group communication globally without expensive hardware or radio infrastructure.

Key Capabilities
  • Unlimited Range: Operates over cellular networks (3G, 4G, 5G, GPRS) and Wi-Fi to eliminate geographical limits, repeaters, and licensing fees.

  • Massive Scalability: Supports up to 512 users per channel and 256 channels per system, with custom user access and priority channels.

  • Intelligent UI: Features an active talker display (works in the background), live user presence lists, and direct integration with physical device PTT buttons.

  • Crystal-Clear & Secure: Delivers HD audio with built-in encryption to keep team communications private and reliable.

REAL-TIME Environmental Hazard Alerting

Aspect Link seamlessly integrates Dräger portable gas monitors with the Atlas SOS App, dedicated Atlas smart devices, and the Aspect Link monitoring platform. This integration turns portable gas detectors into connected safety endpoints, ensuring that hazardous gas exposures instantly trigger automated emergency workflows across your organisation.

Key Capabilities
  • Zero-Touch Emergency Dispatch: Gas threshold breaches automatically trigger emergency alerts, ensuring protection even if a worker is incapacitated by gas exposure.

  • High-Risk & Hazardous Zone Compliance: Combines Dräger's gas detection precision with ATEX-certified Atlas hardware (e.g., Atlas Ex760) for safe operation in explosive atmospheres.

  • Unified Responder Visibility: Aspect Link routes gas emergency notifications directly to responder devices via the Atlas CM app, interactive SMS with map links, or web browser dashboards.

  • Automated Physical Hazard Mitigation: Incoming gas alerts can be configured in Aspect Link to trigger external actions automatically, such as activating local warning lights/sirens, starting emergency ventilation fans, or opening access doors for evacuation.

INTELLIGENT Incapacitation Alerting (Man Down)

True Man Down Detection features delivers potentially life-saving automated protection for lone workers operating in high-risk or isolated environments. Unlike simple drop sensors or fall detection that trigger frequent false alarms, True Man Down uses advanced multi-sensor analysis to detect true incapacitation, ensuring help is dispatched immediately when a worker cannot call for help themselves.

Key Capabilities
  • Zero-Touch Emergency Activation: Designed to send an emergency alert even if the lone worker is unconscious or immobilised.

  • Eliminates False Alarms: Configurable angle limits, motion sensitivity thresholds, downtime timers, and pre-alarm durations adapt to specific job roles and physical tasks.

  • Privacy-First Operations: Motion tracking operates locally on the device and only broadcasts location and audio data when an active alert is triggered.

  • Cross-Platform Availability: Integrated directly into the Atlas SOS App (iOS & Android) and supported across all dedicated Atlas hardware devices (including ATEX hazardous-zone models).

  • Centralised Admin Control: Administrators can remotely configure sensitivity settings or allow users to toggle the feature on/off based on risk assessments.

COMPLIANCE and Usage Monitoring

Aspect Link enhances compliance and usage monitoring to ensure lone workers consistently follow safety protocols and reduce operational risks. Our web-based platform delivers real-time oversight and seamless integration, helping organizations meet legal health and safety obligations while protecting remote staff.

Key Capabilities
  • Live Status Oversight: Provides a real-time dashboard and historical insights into lone worker activity, device performance, and critical alert response metrics.

  • Integrated Safety Hardware: Unites Dräger gas detectors directly with the Aspect Link system, combining advanced environmental hazard detection with automated lone worker protection.

  • Audit-Ready Compliance: Tracks user adherence to safety procedures and check-ins, creating verifiable records that demonstrate proactive duty of care.

INSTANT Communications with Lone Workers

LinkStream Audio™ is a real-time communication technology developed by Isle Systems.

In critical situations, LinkStream Audio™ acts as a vital lifeline by facilitating immediate, automated voice communication between a lone worker in distress and responders.

Key Capabilities
  • Automatic Two-Way Communication: When a lone worker triggers an alert, LinkStream Audio™ automatically establishes a live, two-way audio channel. This allows responders to instantly speak with the worker and hear what is happening in their environment.

  • Incapacitation Support: If a worker is injured, unconscious, or unable to physically answer a phone call, the automatic connection ensures that responders can still listen in to assess the situation without requiring any manual interaction from the user.

  • Centralised Alert Recording: Through Isle Systems' Aspect Link responder platform, these emergency audio streams can be recorded. This is highly useful for post-incident analysis, training, and meeting legal or compliance requirements.

  • Cross-Device Compatibility: It is seamlessly integrated into the Atlas SOS app as well as dedicated smart lone worker devices.

  • Multi-Network Reliability: To ensure the audio stream goes through even in challenging environments, the system utilises robust routing across WiFi and cellular data (GPRS, 3G, 4G, 5G).

SHARE Devices? Always Know Who Has Them

Aspect Link streamlines shared-device management by enabling quick user check-outs and automated data wipe routines upon charging, ensuring responder awareness while maintaining user privacy and ready-to-go hardware.

Key Capabilities
  • Rapid User Assignment: Operators scan a personal QR code or enter details manually on collection to attach their identity and contextual details to the active device.

  • Automated Device Clearing: Docking the device into its charger automatically wipes all user data from the local app, instantly preparing it for the next shift.

  • Flexible Monitoring Modes: Choose between complete data erasure across the entire system upon charging, or local device clearing with centralised logging in Aspect Link for audit and usage reviews.

EXPOSURE Monitoring and Reporting with Dräger
Aspect Link integrates seamlessly with Dräger portable gas monitors to deliver centralised exposure monitoring, dynamic visual alerts, and comprehensive safety reporting directly within the management dashboard.

Key Capabilities
  • Colour-Coded Status Tracking: Instantly categorises gas readings into colour-coded thresholds (Normal, Alarm 1, and Alarm 2) and displays each live reading as a percentage of Alarm 1 for rapid risk assessment.

  • Dynamic Exposure Graphing: Overlay alarm bands, 8-hour Time-Weighted Averages (TWA), and 15-minute Short-Term Exposure Limits (STEL) directly onto trend graphs to visualize exposure over time..

  • Factory & Custom Thresholds: Pre-configured with Dräger factory settings by default, with custom display thresholds clearly highlighted in orange to easily identify modified safety parameters.
