3-1-1 About GAS DETECTOR MANAGER
GAS DETECTOR MANAGER is a Web application that connects the product to a PC, allowing real-time
monitoring of the status of this product and changes in network and alarm setpoint settings from a Web
browser. GAS DETECTOR MANAGER also displays an event history (alarm history) and calibration
history and can be used to run calibrations and alarm tests.
GAS DETECTOR MANAGER has a user mode and an administrator mode; each mode has different
functions.
<User mode>
Displays basic product information, such as the gas names and alarm setpoints, as well as event history
(alarm history) and communication history.
