6.12.4 ADDITIONAL BUTTONS
Four additional buttons are provided on the front panel of the Gas Monitor AMC-1DBx.
• TEST Pushbutton
While pressed, this pushbutton causes continuous activation of all relay outputs
(energized or de-energized, depending on configuration), activation of the system
fail relay output (to the de-energized state), and continuous activation of the
audio alarm (if enabled). Sensor processing and updating of internal status and
timers continues. When released, all outputs return to normal operation.
• HOLD Pushbutton
While pressed during normal operation, this pushbutton freezes the display on
the currently displayed sensor until released. Upon release, the display
immediately advances to the next sensor (depending on the display mode
selected), allowing the HOLD pushbutton to be used to quickly step through
multiple sensors.
• SILENCE Pushbutton
When pressed, this pushbutton silences the audible alarm indication resulting
from all active sensor alarms for an individual, adjustable, preset length of time
within the range of 0 to 60 minutes or infinite. Set its value to “0” to disable the
acknowledge feature.
You can configure this pushbutton to also reset all associated relay output
indications, subject to defined minimum run times for each relay.
Pressing the SILENCE pushbutton in response to new or recurring alarm
conditions resets the acknowledge timer to the preset time, including conditions
previously acknowledged.
Note:
Sensor failure indications cannot be acknowledged except to reset the
system fail relay.
• RESET RELAY Pushbutton
When pressed, this pushbutton resets any latching relays, providing the alarm
condition has subsided.
