LX Series Lever Operated Openings

The LX Series exemplifies Syntégra’s “deeper integration” attitudes and goals. The central lock case accepts handles and keyed cylinders from either and/or both sides. The lock case is configurable with the same popular functions offered in conventional locksets, but we can also do much more. The lever handles are protected by a break-away clutch allowing these systems to be used in the most abusive and demanding applications. Syntégra door systems do not use bulky escutcheons, roses, or edge plates to hide door preparations and mechanisms. Only the vital elements that are needed for operation are exposed, and everything else is concealed and protected.

Imagine being able to operate and secure each leaf of a pair of doors independently without the need for coordinators, astragals, and manual flushbolts. Pairs and single doors also benefit in concealing the side latch and strike from view and tampering by latching at the top of the door. With electrical functions such as electrified lever (ELS) and electrified latch retraction (ML), the LX Series will interface with virtually any access control and door automation system.

Typical Applications

Single doors, pairs and double egress pairs found in the following applications:

  • Areas of Refuge – Stairwell, Elevator Lobby, Elevator Cab
  • Office single and pairs
  • Main entrances
  • Surgical suites

Electrical Options
ML - Motorized latch retraction quietly and efficiently retracts the latch(es) and pushbar when energized. Configured for fail-secure to comply to fire ratings.
ELS - Electrified lever. Energizing allows lever to rotate to retract the latch(es). Fail-Secure or Fail-Safe available.

LatchboltsTop latching standard with – 7/8" (22.2 mm) throw. Projection type Friction limiting-design with deadlatch feature. Bottom – Massive Stainless Steel 5/8" throw bolt with conical tip.
Optional Keyed CylinderStandard diameter Mortise Cylinder with "standard" cam. Accepts 1" cylinder length or greater. A 1" cylinder length does not require a collar. Anything above this cylinder length will require a spacer collar equal to the dimension in excess of 1". (Example 1-1/8" length requires a 1/8" collar).
Back-to-back CylindersRequires a 1/4" collar for a 1" cylinder length. For longer cylinders, add the dimension in excess of the 1" cylinder length to the collar thickness. (Example 1-1/4" cylinder length requires a 1/2" collar).
