4.7 Relay Latching

Each alarm relay has the relay latching option. This controls the alarm behavior after an alarm has been activated
and the gas concentration returns below the alarm level.
Latching On – When the relay latching option is set to "On" and the gas concentration triggers the alarm, the relay
will not deactivate when the gas concentration drops below the alarm level. The power will need to be interrupted
or the "ENTER/TEST" button pressed to un-latch (turn off) the relay condition.
