features the following
options
that
can be configured using the GCT IR Link,
MGC
-S Dock or MGC-S Wall Mount Dock
:
User Message - An optional, user-programmable, text message can be used to show
company branding, a unit identifier or any other pertinent information. The User Message
will be displayed right after the date and time each time the Main Menu is accessed.
Alarm Limits - Each sensor contains separate alarm threshold values that tell the detector
when to go into alarm. Alarm limits may be disabled by setting them to zero.
Caution:
Confirm alarm levels with local laws/regulations before operation.
SAFE Display -
If Safe Display is enabled, screen will display
“SAFE”
if there are no gas or
instrument alerts
.
Self-test Lock -
If
a sensor
fails a
self-test, the detector shows
“E
rr
”
on the display
and
goes
into high alarm.
By default, the alarm can be silenced by pressing the power/menu button.
The self-test lock option
prevents
the alarm
from being silenced
.
Maintenance Notification - If maintenance notification is enabled, the detector will
periodically flash the maintenance LED when a bump test or calibration is due. Otherwise, if
the option is disabled, the detector will only show the maintenance text on the display.
Dock Lock - Dock Lock prevents bump tests and calibrations without the use of the GCT IR
Link, MGC-S Dock or MGC-S Wall Mount Dock.
Latching Alarms -
Alarms are non-latching by default
,
so the detector will cease to alarm and
return to normal operation when
the
gas readings fall back within the set limits.
Latch
ing
alarms
will hold the detector and its display in its peak alarm condition until the power/menu
button is pressed.
TWA Method - The algorithm used to calculate the TWA can be set to either an average over
a moving window (OSHA) or as a cumulative average (ACGIH).
