Power Requirements for Vault 20 FXThe CyberKey Vault 20 FX is designed to receive primary power from a 12 volt DC, centerpositive, power supply transformed from 110-220V AC power. It will require 1AMP minimum.The Vault 20 FX manufacturer offers both 110V and 220V power transformers.In addition, two backup power sources may be employed.Battery - The Vault 20 FX is designed to use a HR 1221W F2 Sealed Lead-Acid battery.Battery output is 12 volts, 4 Amp/Hours. On its own without POE the fully charged batterycan typically provide operational power to the Vault 20 FX for 5 hours or more with typicaluse. When primary power is restored, it will recharge the battery at a rate of approximately10% of capacity. At that rate, a Vault 20 FX that has run on battery power forapproximately 2½ hours will return to fully charged within 5 hours after transformer poweris restored.Power Over Ethernet - POE may be used as a source of trickle charge to extend thebattery life while it is providing power to the Vault 20 FX. With moderate use (issuing up to100 keys per day), and a battery in good condition POE can keep the cabinet batterycharged enough to power the cabinet for several days. This is not, however,recommended as a source of power long term.Note: Although the Vault 20 FX hub has a Molex® Mini Jr Series connector for a backupbattery, that connector should not be used when the hub is installed in a Vault 20 FX becausethe hub does not supply power to either the main power board or the key retainer modules ofthe Vault.
