Fire and Gas Detection System

The new Sierra Monitor (USA) Sentry IT Fire and Gas Detection System builds upon the Sierra Monitor heritage of “Best in Class” intelligent hazardous gas detection. The capability of simultaneous interface via RS-485 Modbus, Analogue 4-20, Relay contact and SentryBus insures that both new and legacy sensor modules can be deployed. Sentry Commander Logic insures that complex algorithms such as zone voting, delay timing, multiple unique alarm levels and other special requirements can be implemented with simple user configuration at the spreadsheet level.

Key features of the Sentry IT Controller include: Intuitive operator interface – touch panel colour display with menu-driven prompts; Versatility – multiple input types, multiple communication choices; Scalable – deploy additional I/O blocks to expand capability; User configurable alarm logic – powerful Commander logic allows user to develop comprehensive alarm and control schemes; User simplicity – auto discovery of sensor modules; single-person, auto-adjusting non-intrusive calibration; multiple choices of main screen; and Easy interface to plant-wide systems – optional embedded web site interface and a selection of multiple protocols enables fast interface to plant control systems.
