(Factory-Set Value)
Description
Channel Status
(Factory setting depends on
what detectors are factory
installed.) 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, 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.
