Visual inspection
At least every 3 months to determine operational readiness. Inspect
the complete VarioGard system for damage and check that gas access
to the transmitters is unobstructed.
Routine inspections
As required by local regulations (in Germany, VDI 2053 - Ventilation
and air conditioning systems for car parks and tunnels / car parks,
State car parks ordinance, etc.). Dräger recommends having the
system inspected by Dräger Service at least once a year.

Replace battery (emergency flashing light power supply) in
central unit.

points labelled with

wand on the contact points for
calibration.

registered, the display reads e. g.: Register slave ?
8 Slave registered !
