Stairwell door fire safety/security

IBC requires positive latching at all doors, and passage between stairwell and floor served.

Buildings that require stairwell security require electric strikes or trim to achieve this.

Electric strikes will only comply with both if Hi-Tower strike is used. Otherwise utilize electrified cylinder trim (with electric hinge). Or other options, like these.
