About this item
The institution function is the most restrictive cylindrical lock function available. Both levers, inside and outside, are always fixed. Neither lever operates the latch at any time without a key. The latchbolt retracts only when a key is inserted in the corresponding cylinder and turned. There is no free lever operation, no push button, no turn piece, and no inside egress without a key. This is not a standard commercial lock. It's a controlled-egress specification for psychiatric facilities, behavioral health units, forensic care rooms, secure observation areas, and correctional settings where managing both-direction passage is a clinical or security requirement for the specific opening.
The Cal-Royal ICCGN09 delivers that function in a Grade 1 SFIC-compatible cylindrical lock at a practical cost point. It accepts BEST, FALCON, and ARROW compatible small format interchangeable cores in 6 or 7 pin configurations. The core is not included. For compatible SFIC cores and cylinder options, browse our cylinders, cores, and keys catalog. For all Grade 1 commercial locks, view our commercial locks catalog.
AHJ Compliance Note
Building codes and Life Safety Code restrict where egress can be controlled from the inside. The institution function cannot be installed on fire exit doors or in any location where life safety code requires free egress without a key. This function is only permitted in specific, documented exceptions: certain behavioral health facilities, psychiatric units, and correctional applications with express AHJ approval. Always confirm with the Authority Having Jurisdiction before specifying ANSI F92 on any opening. Failure to do so can create hazardous conditions in an emergency.
How ANSI F92 Institution Function Works
From outside: insert key in outside cylinder, turn, latchbolt retracts, door opens. Outside lever is always rigid otherwise. From inside: insert key in inside cylinder, turn, latchbolt retracts, door opens. Inside lever is always rigid otherwise. There is no mechanical way to operate either lever without a key. The door cannot be opened from either side without key operation. Closing the door does not change the locked state of either lever.

Cal-Royal Clutch System
The ICCGN09 includes Cal-Royal's Clutch System, a freewheeling lever design that deters handling breakage in high-abuse environments. When excessive rotational force is applied to a fixed lever, standard lever designs transfer that force into the spindle and internal mechanism, eventually causing structural failure. The Cal-Royal Clutch System allows the lever to freewheel under that force, absorbing the energy without transferring it into the chassis. The lever returns to position normally for key operation. This makes the ICCGN09 more durable in behavioral health and institutional environments where patients or detainees may attempt to force-operate fixed levers.
ICCGN09 vs. CAT09: SFIC vs. Conventional Cylinder
The Cal-Royal CAT09 is the institution function (ANSI F92) with a conventional cylinder prep. The ICCGN09 (this product) accepts SFIC cores for facilities running BEST, FALCON, or ARROW interchangeable core master key programs. Both provide the same institution function. Select ICCGN09 if your facility uses SFIC master keying; select CAT09 if your facility runs conventional cylinders.
