38 • Viewing and Changing Channel Parameters Beacon 410 Gas Monitor Operator’s Manual
Table 7 below lists the channel parameters that can be viewed and updated in the
Configuration Menu along with the factory set value for each parameter.
Table 7: Configuration Menu Parameters
Channel Parameter
(Factory-Set Value)
Description
Channel Status
(Factory setting depends on
whether a detector is supplied
for a channel.)
If set to ACTIVE, the channel will be fully functional.
If set to STANDBY, the channel’s gas name and reading will be
replaced by STANDBY on the display. The channel’s relays will be
fixed in their non-alarm state and the 4 - 20 mA output for the
channel will be fixed at 3.5 mA. This setting is typically used when
maintenance is being performed on a channel.
If set to NOT USED, the channel is not functional and the gas
name and reading field for that channel indicates NOT USED. All
the channel’s relays are de-energized and the 4 - 20 mA output is
fixed at about 0.7 mA.
Strobe Setting
(USE w/ Alarms Only)
If set to USE w/ Alarms Only, the strobe will activate when the
appropriate gas alarm condition occurs as defined in the alarm
strobe settings (see below) in the Configuration Menu. It will not
operate when a fail alarm occurs.
If set to USE w/ Alarms and Fail, the strobe will activate when the
appropriate gas alarm condition occurs and when a fail alarm
occurs.
If set to DON”T USE, the none of the strobe alarm settings appear
in the Configuration menu and the strobe circuit does not function.
* This parameter appears only if the STROBE Installation
parameter in the Global Menu is set to Strobe Installed.
Alarm-1 Level
(See the Beacon 410 Detector
Head Specification sheet for the
detector head installed on this
channel.)
The gas reading at which an alarm 1 condition occurs and the
Beacon 410 activates the alarm 1 circuit for this channel.
Alarm-1 Inc/Dec
(DECREASING for oxygen,
INCREASING for all other
channel types)
Indicates if the alarm 1 circuit is activated by gas reading
INCREASING or DECREASING to the alarm 1 level.
Alarm-1 Latching
(LATCHING)
If set as LATCHING, you must press the RESET button to reset
the alarm 1 circuit after the alarm 1 condition passes.
If set as SELF-RESETTING, the Beacon 410 automatically resets
the alarm 1 circuit after the alarm 1 condition passes.
Alarm-1 ON Delay
(1 Second)
The amount of time the Beacon 410 delays activation of the
alarm 1 circuit after the gas reading reaches the alarm 1 setpoint.
ALARM-1 OFF DELAY
(0 Seconds)
The amount of time the Beacon 410 delays resetting the alarm 1
circuit after the alarm 1 condition passes.
* This parameter appears only if the ALARM-1 Latching
parameter is set to SELF-RESETTING.
