The Dräger VarioGard® Battery Module is an accessory to the Dräger VarioGard® gas warning system. As a power failure turns out, 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.
