Caution
The alarm check conducted with the Test switch will also activate the gas alarm contact. For
this reason, if alarm contacts are used for interlocking with external devices, be sure to check
that the interlock be released prior to conducting the alarm test. Also, be sure to carry out alarm
testing with the test switch after setting in maintenance mode. (Refer to 7.5 Maintenance Mode
Settings and Operating Instructions.)
Relevant personnel should also be notified of the inspection in advance.
