How We Help Outreach How does installation work? The installation of the unit is the responsibility of the host organisation to coordinate. We have an installation guide we can share with you; this provides all the information your electrician may need. Our full defibrillator package comes with a branded, unlocked, polycarbonate cabinet with temperature gauge. We strongly suggest this is installed by a qualified NICEIC registered electrician. The defibrillator itself operates through batteries; however, the cabinet needs to be connected to the electrics via a 3-amp fuse spur. This provides heat in cold weather to protect the device by preventing freezing and condensation. Manage Cookie Preferences
