Hazardous Gas Monitoring System Includes Multiple Alarm Levels

The new Sierra Monitor Sentry IT fire and gas detection system is capable of simultaneous interface via RS-485 Modbus, Analog 4-20, Relay contact and SentryBus. This ensures that both new and legacy sensor modules can be deployed. 

Sentry Commander Logic ensures that complex algorithms such as zone voting, delay timing, multiple unique alarm levels and other special requirements can be implemented with user configuration at the spreadsheet level.

Sentry IT Controller features include a touch-panel color display with menu-driven prompts and multiple input types and communication choices. It also provides the ability to deploy additional I/O blocks to expand capabilities and commander logic that allows user to develop comprehensive alarm and control schemes.
