Page 21: Menu Functions
SENSEPOINT RFD OPERATING MANUAL RFDMAN MAN0843 Issue 3 The transmitter automatically returns to normal gas detection mode from any configuration menu if a button is not pressed for 30 minutes (unless the menu Timeout option is disabled, see the P-07 menu option). -
Page 22: First Time Switch On
When in calibration mode the current output from the detector is inhibited (2mA default) to avoid false alarms. Note: Honeywell Analytics recommend the maximum time between calibrations should be no more than 6 months. It is recommended that the calibration is made where the sensor/transmitter have stabilized with their local environment. - Page 23 Should the target gas not be listed in the selected sensor manual contact your local Honeywell Analytics representative for more information. Sensepoint RFD is limited to the star ratings and ranges listed in the table below: RFD selected Gas star...
