Alert Types

Audible, visual, and vibrating alerts enable prompt action during emergencies. The SC500® alerts can be configured using the PC Utility tool.

Rugged IP67 Rating

The SC500® is designed to withstand dust, water, and harsh environments, ensuring device durability and reliability.

GPS Capability

The optional GPS feature allows accurate outdoor positioning of SuperCELL® devices, enabling precise mapping display on Grace Connected Safety™.

Motion Detection

Activated when the SC500® stops moving, a countdown initiates from a default 90-second duration. A pre-alert tone encourages user movement; if unresponsive, the alarm escalates audibly and transmits to the Grace Gateway. Motion time settings can be customized using the PC Utility tool.

Distress Alarm

The SC500® features a distress alarm button for manual activation in emergencies.

Pendant Buddy System

An optional feature allowing other Grace SuperCELL® devices to receive alarms if an SC500® is in distress, notifying nearby personnel.

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

The SC500® contains a rechargeable lithium battery, charging in approximately 6-8 hours using a standard AC adapter or optional 12V DC vehicle charger. Non-GPS models offer up to 40 hours of operation, while GPS models provide 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.


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.
