1.4 ALARM DISABLE
The alarm disable switch, located on the front panel (figure 3), operates by removing DC common from the
“Alarm Coil Power” terminals. Disabling of alarms does not inhibit any function of the Model 12B digital control
modules. The digital display, alarm LEDs and on board alarm relays remain active.
1.5 REMOTE ALARM RESET
A remote mounted normally open momentary switch may be used to reset the alarms of all Model 12B controllers
(figure 4). The reset function is effective when the Model 12B’s respective alarms have been programmed in the
latching position and alarm conditions have passed. Each Model 12B controller has its own alarm reset switch
which is discussed further in section 2.0.
