The Next Generation of Access Control

Medeco began providing electronic locking systems in 1992 when the company y introduced the first high security electronic lock into the payphone industry.  Nearly 1 million electronic locks were installed in payphones throughout North America. Medeco...

Unlike a mechanical lock having a mechanical code, the NEXGEN lock uses an electronic code that changes on every opening.  Also the locks are powered by the key eliminating the need for local power at the opening. This allows for installations in even the most remote sites or demanding installation conditions. 

Every time a NEXGEN key is inserted into a lock, the date, time, and serial number is recorded in both the lock and key memory.  This audit information is uploaded from the key into the host. Printable reports identify the date and time that each lock was accessed, or an attempt was made.  The software immediately gives notice of any exceptions, including unauthorized attempts, out of schedule attempts and re-opened locks.  The lock can store thousands of audit events after which the events are stored in a first-in, first -out format.  A NEXGEN key can store access for over 10,000 locks and thousands of audits. 

If a key is lost or stolen, that key will simply expire at the end of its schedule or can be immediately disabled by modifying the system security level.  The NEXGEN Software monitors key battery levels and indicates when batteries are becoming low prior to keys going to the field.  There are two battery options - key field replaceable battery or rechargeable battery.



The new Nexgen XT platform was developed to incorporate the features of the NEXGEN products in a small form factor.  The Medeco Product Development Team was given the task of miniaturizing the NEXGEN key to a point where it could fit on a standard key ring and fit comfortable in someone’s pocket.  Also the electronics of the lock were to be reduced to a size where they could fit into a Small Format Interchangeable Core (SFIC) cylinder shell.  While initial cylinder offering is only available in SFIC, many other cylinder types will follow in the coming months.

Like NEXGEN the Nexgen XT cylinder is an electronic only cylinder which was designed for use in the harshest environmental conditions.  Following in NEXGEN’s footsteps Nexgen XT cylinders are powered by the key which allows you to install the cylinders with no door modification, and no local power is required. 

The cylinder and the key both maintain an electronic record of each time a key opens or attempts to open a cylinder.  The cylinder will hold up to 2000 audit events.  When the maximum number of audit events is reached the cylinder will record events on a “First In First Out” basis.  If a key is missing from the system, the electronic identity of the key can be placed on the cylinder’s “Black List.” The “Black List” is maintained at the cylinder and if a key on the list attempts to open the cylinder it will be denied access.  If the key is later found it can easily be taken off of the list and placed back in service. 

The Small Format Interchangeable Core cylinder will install in any SFIC or “Best” style housing.  The deadlatch control sleeve can be actuated by any key programmed as a “Control Key.”. This allows the user to quickly install or remove cylinders and makes system adjustments simple without the need for a dedicated “Control Key.” 

The Nexgen XT key has a small ergonomic design, about the size of a memory stick, which easily fits on a standard key ring.  The key is weather resistant for use in damp conditions and the housing is made of stainless steel for extreme durability.  The key houses a rechargeable lithium polymer ion battery which powers both the key and the cylinder.  The use of lithium polymer ion technology allows the key to open 500 to 800 cylinders before needing to be recharged.  The key can be recharged using the desktop cradle or the portable charging station.  The power source for either charger can be a 120 VAC outlet, a 12 volt car accessory port, or a computer USB port.  The key will let you know when it is needs to be recharged with an indication from the two onboard LED indicators. 

The key memory will allow for storage of up to 5000 audit events.  An audit event will be stored in the key each time the key accesses or attempts to access a cylinder.  The key will hold access right for up to 5000 cylinders and is programmed using the Nexgen Security Manager Software and the Desktop Programming Station.
