Fire and Gas Safety Solutions

Sierra Monitor combines intelligent re and gas detectors with controllers that provide timely
status enabling safety professionals to react quickly to changing conditions. From the rst Sentry
controller released in 1986 to today’s powerful Sentry IT System, Sierra Monitor has been a leader
in intelligent hazardous gas detection systems, smart single-point xed gas detectors and a
broad range of ame detectors.

Sierra Monitor detectors meet your needs for intelligent monitoring of:

Fire/Flame
Combustible gases – posing a risk to personnel and facilities through re or explosion

Toxic gases – creating both immediate and long term risk to personnel
Oxygen displacing gases – depleting workers’ oxygen supply in conned spaces

–

resulting in explosive conditions and caused by variety of sources

Information Technology at the System Level

From simple alarms to sophisticated systems integrating re and gas detection, logic controls,
graphical interface and remote web server displays, the Sentry IT Controller is “Best of Class”. The
Sentry controller heritage continues to emphasize Information Technology as a key ingredient of
system design. The capability of simultaneous interface via analog 4-20 mA, RS-485 Modbus,
Relay contact and SentryBus insures that both new and legacy sensor modules can be deployed.
Sentry Commander Logic insures that complex logic such as zone voting, delay timing, multiple
unique alarm levels and other special demands can be met with simple user conguration at the
spreadsheet level.

Key features include:

Versatile – multiple input types, multiple communication choices, full function controller
Scalable – deploy additional I/O blocks to expand capacity
Intuitive operator interface – touch panel display with menu-driven prompts to

reduce learning curve

Cost eective
Simultaneous communication methods – Modbus, 4-20 mA (2, 3, 4-wire), SentryBus

and Relay inputs and outputs

Multiple power options
User congurable alarm logic – menu driven conguration and integral Commander

Logic allows the user to develop comprehensive alarm logic schemes incorporating
delay times (on and o), relay acknowledgement, zoning, voting groups and more
User simplicity – auto discovery of sensor modules, single person, auto-adjusting
non-intrusive calibration
Easy interface to plant wide systems – FieldServer inside means multi-protocol and
Web Server interfaces always available for plant wide integration. Multi-Protocol
includes Modbus TCP, EtherNet/IP, Probus, DeviceNet, ControlNet, DNP, OPC, BACnet,
LonWorks and many more from the extensive FieldServer protocol library. FieldServer
