Sentry

Gas Sensor Modules

Two types of gas sensor modules are available for the Sentry Gas Risk Management System. For the more common gases such as Combustible Gas, Oxygen, Carbon Monoxide, Hydrogen Sul- fide, Chlorine and Ammonia, Sierra Monitor offers the IT Series Smart Gas Sensor Modules. More information on the IT Series is available in the spe- cific IT Series data sheets. For other gases Sierra Monitor offers the 5100 Series Gas Sensor Mod- ules described in this data sheet.

Sierra Monitor toxic gas sensor modules utilize elec- trochemical technology to achieve the most accu- rate and reliable monitoring of gas concentration. All Sentry 5100 Series sensor modules easily in- terface to the Sentry controller. Each module has a unique address, which allows signals from mul- tiple modules to be multiplexed for communication with the controller on the same cable. All Sierra Monitor gas sensor modules are designed for hos- tile or hazardous environments and are in enclo- sures approved for Div. 1, Class 1, Groups C, D locations.

SENTRY FEATURES INCLUDE:

Digital Signal Transmission Serial communication to the controller enables multiplexing sensor modules on a signal cable, significantly reducing installation costs. This assures RFI and EMI immunity over extended distances.

One-Person, Non-intrusive Calibration In the calibra- tion mode, sensors continue to monitor for hazardous conditions until calibration gas is applied. All adjustments are made automatically after calibration gas has been re- moved. Sentry notifies the operator of calibration comple- tion and allows acceptance or rejection of the calibration at the controller keypad. There are no manual adjust- ments required at the sensor module.

Low Sensitivity Check Automatic, post-calibration check of sensor for proper output. Low sensitivity alpha- numeric message warns of need for sensor maintenance.

Power Up & Calibration Delays At start-up or calibra- tion the output of the sensor is locked out and remains locked for five minutes to avoid erroneous readings during the warm-up period and after calibration.

Diagnostic Information The alphanumeric display on the Sentry Controller provides easy to understand diag- nostic messages.
