12
instruments. Each LENS group can include Ventis Pro Series instruments, Radius™ BZ1 Area Monitors, or
both.
As groups are formed, if instrument "A" belongs to a LENS group and instrument "X" connects to
instrument "A", instrument "X" will be connected to all peer instruments in the group. When any peer-group
gas-detection instrument is within range of any other instrument in the group, they share their alarms, gas
readings, and other data. This allows in-field personnel to learn of and respond to hazardous events or
conditions that originate with any instrument that is operating in a LENS group.
Data communicated using LENS Wireless can be secured with the default encryption key from Industrial
Scientific. LENS allows for the customer to optionally use its own custom key*. When an encryption key is
used, data are encrypted during the instrument-joining process.
LENS functionality requires no central controller, network configuration, or infrastructure.
*Requires iNet Control or DSSAC (Docking Station Software Admin Console) from Industrial Scientific.
iAssign™
Programmed iAssign™ tags can be used by the instrument operator to assign an instrument to the user-
site data on his or her tag. This can help promote a sense of ownership among instrument operators,
encouraging their responsible use of the equipment. User and site values are also associated with alarm
events and other instrument data that are important to users of Industrial Scientific software products.
The iAssign Beacon is used to change an instrument's site assignment as the instrument enters or leaves
the Beacon's range. It is also used to help restrict access to an area: an instrument's "proximity alarm" will
be activated when the access level for its current user assignment is lower than the Beacon's access
setting.
Panic and man-down features
The panic button provides instrument operators with the ability to turn on the instrument’s high-level alarm.
This can signal others who are nearby that the instrument operator is in distress, someone else is in
distress, or there is some concern about in-field circumstances.
The man-down feature allows the instrument to sense when
it
has not moved. A man-down warning or
alarm may indicate the instrument operator is unable to move or press the panic button, or that the
instrument has become separated from its operator. Both the warning and alarm can be turned off by the
user.
Gas-alert and -alarm features
The optional "acknowledgeable gas alert" feature warns the instrument operator of the presence of gas in
concentrations that may be approaching the instrument’s alarm setpoints. This can prompt the instrument
operator to check the display screen for gas readings and for an optional instructional message; the
instrument operator can reset the alert.
The safety team can provide instrument operators with up to 26 customized, instructional messages*. The
opportunities include a message that displays during the start-up sequence and those that display during
gas events. A unique "alarm action message" (e.g., "EVACUATE") can be set for each of these events for
each installed sensor: gas present (alert, low alarm, and high alarm), STEL, and TWA.
The optional "full screen alarm" setting is used to display easy-to-read alarm details in large type.
