Lockwood Nexion Functionality The unique Safety Release™ feature automatically unlocks the internal handle upon entry, minimising the risk of being locked in. The Nexion incorporates the unique LockAlert® status indicator that shows the lockset mode at a glance. The Nexion meets or exceeds the highest security and durability requirements in Australian Standard AS4145.2:1993 when fitted to an exterior quality door. The lockset can operate in three modes: Secure Mode, Safety Mode and Passage Mode. Secure Mode - Red IndicatorHandles securely locked from both inside and outside.This mode enables total security when leaving the property. The lockset cannot be opened from the inside without a key. Safety Mode - Yellow IndicatorHandles securely locked from outside and free from the inside.This mode prevents unauthorised entry while making it easy to exit the property. A lockout release function is incorporated which automatically changes the lockset to passage mode when the door is opened from the inside. This minimises the chances of being accidentally locked out. Passage Mode - Green IndicatorHandles free from both inside and outside.The passage mode gives convenient access from inside and outside without the need for a key. A single cylinder version is available which disables the Secure Mode function and has no internal cylinder function. This means the inside is free to exit at all times.
