Temporary Horn Disable
Pressing the Test/Reset button temporarily silences the horn. The horn
slash through icon will be on the display indicating that the horn is
temporarily disabled. If the horn is temporarily disabled, it will turn off
and not come back on until either the temporary horn disable timer
expires or until the monitor detects another alarm condition. See
Configuration Parameter P03 for programming the timer.
Permanent Horn Disable
The horn may be permanently disabled during normal operation by
pressing and holding the Test/Reset button for five seconds. After five
seconds, the horn slash through icon will continuously flash on the
display indicating that the horn is permanently disabled; the horn will
no longer sound in an alarm zone or when any alarm input is activated.
Removal of power to the monitor does not change this setting; upon
restoration of power, the horn will still be disabled. The horn may be
re-enabled by pressing the Test/Reset button for five seconds. The
flashing horn slash through icon will then be shut off.
Viewing Alarm Set Points
The alarm set points may be viewed during normal operation by
pressing the Up and Down Buttons. The Up Button is to the right of the
green LED. The down button is to the left of the red LED. A
straightened out paper clip works well to access them. If the Up Button
is pressed, the display will toggle between the current reading and the
High Alarm set point. If the Down Button is pressed, the display will
toggle between the current reading and the Low Alarm set point.
The display will toggle between the current reading and the selected set
point until there is no keypad activity for five seconds. At that point,
the monitor will return to normal operation and display the current
airflow reading.
Changing Alarm Set Points
The alarm set points can be changed during normal operation and while
viewing a set point by holding the Up Button (High Alarm) or Down
Button (Low Alarm) for five seconds. When the button is first pushed,
the display will toggle between the current reading and the selected set
point. If the button is held for five seconds, the monitor goes into a
program mode that allows changing the selected set point. The
corresponding LED will continuously flash and the display will turn on
the PGM descriptor to indicate that the monitor is in program mode.
