Grace Connected Safety™

Microcell Safety Pendant

MicroCELL® is a low-profile, industrial-grade personal safety and communication device designed for first responders, support staff, and incident response personnel. Compact and wearable, MicroCELL® delivers real-time accountability, emergency alerting, and two-way communication—connecting directly to the cloud without the need for a gateway or fixed infrastructure.

When paired with Grace Connected Safety®, MicroCELL® provides automatic check-ins, GPS location awareness, emergency SOS alerts, and cloud-based messaging, ensuring personnel remain visible, reachable, and protected throughout an incident. Unlike systems that rely on personal phones or on-site gateways, MicroCELL® communicates directly over cellular and Wi-Fi networks, making it ideal for mobile, remote, and rapidly evolving operations.

MicroCELL® is designed to solve the accountability gap during emergency and industrial operations—where not every individual requires a full PASS device, but all personnel must remain connected to command. From on-scene support roles to lone workers operating off-site, MicroCELL® extends safety coverage across the entire workforce.

All monitoring, alerts, messaging, and incident data are securely managed through the Grace Connected Safety® cloud platform, with real-time visibility available via mobile app or web portal.

Microcell Safety Pendant

Alert Types

Audible, visual, and vibrating alerts allow for immediate response in emergency situations. User configurable with PC Utility tool.

Rugged IP67 Rating

Ensuring device is protected against dust, water, and harsh environments.

GPS Capability

Available as an option for true outdoor positioning of WorkForce® devices, allowing for accurate mapping display on Grace Connected Safety™

Motion Detection

Safety feature triggered when a worker safety pendant device stops moving, with a timer counting down from a factory default time of 90 seconds. A pre-alert tone prompts the user to move, and if not reset, the alarm escalates to its audible alarm and transmits back to the Grace Gateway. Motion time settings can be easily configured with a PC Utility tool.

Fall Detection

Activated when a worker safety pendant device detects a fall greater than 4ft. The device enters fall detection pre-alert with an escalating audible tone for 15 seconds, allowing the user to manually reset their WorkForce® device by pressing its side buttons. If not reset within the pre-alert time, a full alarm is transmitted immediately to the Grace Gateway and processed on Grace Connected Safety.

Distress Alarm

WorkForce® devices also have a distress alarm button for manual activation if needed.

Pendant Buddy System

Optional feature that allows other Grace Pendants to receive the alarm when one WorkForce® device is in alarm. If other Grace Pendants are within range of the alarm, they too receive the alarm.

User Friendly & Configurable

The WorkForce® devices are user-friendly, provided with operating and configuration manual and settings changes that can be easily changed via the PC Utility tool.

Rechargeable Battery

Equipped with a rechargeable lithium battery that can be charged in approximately 3-4 hours using a standard AC charger or an optional 12V DC vehicle charger. Non-GPS models can support up to 40 hours of operation, while GPS models can support up to 24 hours.

System Access Loop Test Indicator (SALTi)

When used with Grace Gateways, the system access loop test indicator (SALTi) is designed to confirm that the system is able to meet its requirements and perform as expected. By testing the system access loop, workers can identify and correct any issues before the system is deployed, ensuring that it will function correctly in real-world environments.

APPROVED FOR LICENSE-FREE RADIO RF

Grace Connected Safety™ devices are approved to operate on a license-free radio RF spectrum in North America, Australia, and other select countries, providing greater flexibility and accessibility.
