About this item

The Sargent 8237 is the classroom security function within the Sargent 8200 Series, the Grade 1 mortise lock platform that holds the industry's most demanding independently verified cycle test result at 16 million cycles, 14 times the ANSI/BHMA A156.13 Grade 1 requirement (Verification ID: V584148). For K-12 schools, universities, healthcare facilities, and government buildings specifying classroom lockdown capability on a hardware schedule that demands both life safety code compliance and long-term performance, the 8237 is the established specification.

 

Function 37: How the Classroom Lock Operates

 

The 8237 operates on ANSI Function F05, the classroom function. From the exterior, the outside lever is always locked until key operation retracts the latchbolt. That same key also locks and unlocks the outside lever, which is the intruder lockdown mechanism. A single key turn from inside or outside the room engages or releases the lockdown state without any additional tool, card, or procedure. From the interior, the inside lever always retracts the latchbolt freely, so occupants can exit at any time regardless of whether the outside is locked or unlocked. An auxiliary deadlatch prevents the latch from being shimmed or loided. This is the function that current school security guidelines and NFPA 101 intruder lockdown provisions are written around.

 

Case Construction and Certifications

 

The 8200 Series case is 12-gauge heavy-duty wrought steel, zinc dichromate plated, 7/64 inch (0.109 inch) thick. The inside front is 1/8 inch cold-rolled steel that holds the lock case securely in the door against impact and prying forces. Hubs are cold-forged steel. The auxiliary deadlatch is stainless steel and non-handed. The front plate is 8 inches x 1-1/4 inches, adjustable from flat to a 1/8 inch bevel, meeting ANSI/BHMA A156.115. Only 30 degrees of lever rotation is required to retract the latchbolt, which matters on high-traffic doors where occupants may not achieve a full lever rotation under stress.

 

Certifications: ANSI/BHMA A156.13 Series 1000 Operational Grade 1 and Security Grade 1 with all standard trims. UL-cUL listed for 3-hour fire doors. UL 10C positive pressure compliant. Windstorm rated. 10-year limited warranty on the lock body and components.
