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
(SELF-RESETTING for
oxygen, LATCHING for all
other channel types) 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.
