is an automated personnel accountability and emergency signaling system used with TPass II, LTX200, TPASS 3, and SuperCell. It offers:

The Grace Industries Watchdog will constantly monitor In-Command for proper operation and system integrity. This transceiver manages system radio telemetry and contains a separate audio alarm in the event of PC failure.

Similar to the TPASS 2, the LTX200 is a durable safety monitoring personal distress alarm. This device was designed to detect when there is a lack of motion by the person wearing the unit, at which point the LTX200 will automatically transmit a radio and audible alarm message identifying a man down situation. The LTX200 also includes a manual distress call button. An intrinsically safe, rechargeable product makes the LTX200 the ideal solution for workers who require daily safety monitoring. Automatic or manual activation models are available in a variety of lack of motion timing.
The SC500 is an intrinsically safe two-way signaling device that has the ability to monitor other Grace Industries devices, specifically the SuperCell and TPASS product lines in addition to having its own motion sensing alarm providing its own man down alarm capability. This enables the user to be hands free and mobile while monitoring other safety professionals. The SC500 has text messaging capability and can be pre-programmed with up to 50 messages.
An extension of the TPASS II, the TPASS 3 is a high-performance, intrinsically safe, two-way radio signaling PASS device that also provides automatic and total accountability. In addition, with the Co-Monitoring option it can also receive notification when someone is in alarm. Automatic Activation, manual activation, motion sensing, and temperature sensing models are available. Rechargeable models are also available.
The Grace Employee Monitoring System (GEM System™) provides instant and continuous safety monitoring of personnel. If an employee becomes incapacitated, a personalized distress signal is transmitted automatically, identifying by name, the person in trouble. The GEM System in conjunction with the TPASS II allows one person to effectively monitor the status of hundreds of employees, in a number of areas and/or large groups. Regardless of the size of the personnel base or type of Incident Command System in your department, Grace Industries, Inc. has a GEM System to suit your needs. 2 channel to 16 channel GEM Base Receivers are available.
