VeriSafe 2.0 AVT
INDICATOR MODULE
The 2 .0 AVT isolation module is compatible with up to two indicator modules . The test can be initiated at either location and
results will be shown simultaneously on both indicators . Primary indicator must be installed locally near the isolation module .
A combination of battery-powered and battery-free indicators can be used in either port . Refer to the table below for maximum
system cable length .

NOTES
: 1 . AUX port does not accept battery power .
2 . Battery powered indicator module can be used in the AUX port, however the battery will not
have any impact on powering the AVT .
ABSENCE OF VOLTAGE OUTPUTS
The AVT includes a set of redundant isolated transistor outputs for optional use with control systems . These outputs are located
on the isolation module . These outputs are normally inactive, and are only active when the green absence of voltage indicator is
illuminated . By utilizing these outputs, the AVT can be used to interface with a control system .
Recommended Wiring
Output Specifications
For redundant monitoring of output state .
Outputs are normally inactive, and active only
when absence of voltage is detected .
