Test Menu Overview - Honeywell Midas User Manual

6.3.3 Test Menu Overview '

The test menu is used to test the detector gas
reading using bump test gas, and for simulation of
alarm and fault display and output operation. The
test menu also contains the detector Inhibit facility.
Use the 's' up and 't' down buttons to select either
bump test or alarm/fault test. Press the '3' accept
button to enter that submenu.
The table below shows an overview of the
test submenus and how they are navigated.
For a detailed step-by-step instruction of how to test
the detector operation refer to Section 7.2.
Note
In bump test mode, the Modbus/TCP outputs
are not inhibited. Only the 4-20mA and alarm
outputs are inhibited.
The bump gas test is a functional check only.
Consult local guidelines for recommended
best practices. Bump test concentrations
recommended in Appendix B are calculated
to generate a minimum first alarm level
response.
