LEGRAND DPX3 160 - C - Safety Kit

The following operations must be undertaken to ensure the detector kit works
correctly:
 Perform annual maintenance (cleaning, tightening) on the safety kit.
 Conduct an annual check of the smoke detectors.
 Change the smoke detector as often as recommended in the maintenance guide.
Any failure to follow procedures and warnings to the letter can lead to premature
failure, explosion, or an outbreak of fire in the equipment, and will automatically
invalidate the enclosure warranty.
Beware, the capacitor bank can be under voltage even if the controller is switched off
