The Dräger VarioGard® Battery
Module is an accessory to the Dräger VarioGard® gas warning system. In the event of a power failure, it
ensures that the Dräger VarioGard® system can continue to measure and give alarms for a
period of approximately two hours.
The
operating status of the Dräger VarioGard Battery Module is monitored by the
Dräger VarioGard central unit. An operating lamp signals that the capacity of
the Dräger VarioGard Battery Module is at least 25 percent, while internal
electronics control the recharging of the lead-acid batteries and protect them
from total discharge.
The
Dräger VarioGard Battery Module is available as a wall-mounted unit. The
leadacid batteries need to be ordered separately. A set of lead-acid batteries
comprises two batteries, each with 12 V / 7.2 Ah.
