Alarm Inhibit Screen
The Alarm Inhibit screen allows the user to inhibit alarms for a pre-determined amount of time. The screen is
identified as ‘ALARM INHIBIT’. The screen is typically used to inhibit alarms during calibration of a sensor.
When logged in, selecting the ‘INHIBIT TIME’ field will open a numeric keypad used to enter the length of
time the controller will inhibit alarms. When the amount of time has been entered, select the ‘START’ button
to start the time counter. The controller will inhibit all alarms until the time reaches ‘0’ (zero). While the
Alarm Inhibit counter is running, the field will display ‘TIME REMAINING’ along with the active counter.
The ‘START’ button will change to a ‘STOP’ button which can be selected to exit alarm inhibit mode if the
calibration is completed before the timer runs out or if alarm inhibit needs to be aborted for any other reason.
NOTE:
The user must be logged in to the MCX-32 in order to make changes to the INHIBIT
TIME field in the Alarm Inhibit screen and to be able to start the Alarm Inhibit counter.

Alarm Inhibit Screen
If the Alarm Inhibit screen is exited while in alarm inhibit mode, the Main Display screen will show that the
alarm inhibit function is on by displaying ‘ALARM INHIBIT’ at the top of the screen along with the active
counter.
NOTE:
From the Alarm Inhibit screen, the controller will return to the System Configuration
screen after 1 minute of inactivity and then back to the Main Display screen after another
minute of inactivity. This is normal. Pressing the ‘ALARM INHIBIT’ button will return to the
Alarm Inhibit screen and the timer.
Upon power-up of the controller, the Alarm Inhibit function automatically becomes active and starts a two
minute timer to prevent inadvertent alarms from occurring during initialization of any attached sensors. When
the inhibit timer runs out, the controller will return to normal operation and alarms will no longer be inhibited.
The user can enter the Alarm Inhibit screen at any time by pressing the ‘ALARM INHIBIT’ button and
manually stop the alarm inhibit mode.

Power Management Screen
The controller has the ability to monitor the voltage from the internal power supply, and the auxiliary 24VDC
input voltage to the controller. The Power Management screen provides a digital display of the voltages
applied. If an auxiliary 24VDC is not connected to the controller, the voltage displayed will be correct for the
primary, and the secondary will display 0.00. If an external power source is connected to the auxiliary 24VDC
input, the secondary will display the applied voltage.
