Fire-Rated Stairwell Doors in a Hospital Retrofit
A 240-bed hospital is retrofitting access control on 60 fire-rated stairwell doors. Eighteen doors currently have fail-safe mag locks tied to the fire alarm; six have delayed-egress hardware; none have door-position switches. Request-to-exit is by motion sensors, and maintenance reports 11 nuisance alarms per week, mostly at a cafeteria stair and a loading dock stair. The fire marshal recently cited one door for a blocked egress path and another for a mag lock with no fire-alarm release. The hospital also wants lockdown of two behavioral-health stair doors but must preserve egress at all times. Power transfer to electrified hinges has failed twice, and the doors are 20 years old with closers that do not always latch. The hospital wants one hardware standard across the 60 doors without increasing false alarms.
1. Determine the fail-safe/fail-secure logic and hardware approach for the stairwell doors and the two behavioral-health doors.
Read the worked answer
Stairwell doors are egress doors first. For the 18 mag-locked doors, use fail-safe locks that release on fire alarm and on power loss, with door-position monitoring and a request-to-exit device. Do not use fail-secure hardware on a required egress stair unless a listed controlled-egress arrangement is approved. For the six delayed-egress doors, verify the delay is within the adopted code and that the door releases on alarm; provide signs and annual testing. For the two behavioral-health stair doors, lockdown must not eliminate egress. Use a controlled-egress or delayed-egress arrangement with staff release, door monitoring, and fire-alarm release; a standard mag lock that traps occupants is not acceptable. Because the doors are 20 years old and closers do not latch, fix the door and frame first, then add electric hardware. Power transfer should use a listed transfer device or electrified hinge rated for the cycle count; repeated failures suggest misalignment or wrong hardware, not just a bad part. Standardize on one solution per door type, not one SKU for all 60.
2. Troubleshoot the 11 nuisance alarms per week and propose changes at the cafeteria and loading-dock stairs.

Eleven nuisance alarms per week usually means the request-to-exit sensor is seeing through the door, the door-position switch is misaligned, or the closer is not latching. At the cafeteria and loading-dock stairs, start with a door sweep and a walk test: does the motion sensor detect a person approaching from the secure side, or does it see traffic on the egress side? Replace motion RTE with a more targeted device, such as a push button or a request-to-exit sensor designed for the opening, and align the door-position switch. Check the closer, latch, and strike; a door that does not latch will generate held-open alarms even with a good sensor. Review the alarm delay and shunt settings so normal passage does not alarm, but do not extend delays so far that a propped door goes unnoticed. Trend alarms by door and time to find patterns. After adjustment, monitor for two weeks before replacing more hardware.
3. Outline the code-compliance and testing program needed to satisfy the fire marshal and keep the access-control upgrade defensible.
Read the worked answer
Compliance work should start with the adopted fire code and the facility's life-safety plan, not with the access-control vendor. Verify that each stair door is self-closing and latching, that mag locks release on fire alarm, that delayed egress meets the code limits, and that hardware is operable without a key or special knowledge. The fire marshal citation for a blocked egress path and a mag lock without release must be corrected first. Coordinate with the fire alarm vendor to test release at every door, document results, and repeat on the required inspection schedule. Add door-position monitoring so propped doors alarm locally and at the console. For behavioral health, obtain written approval for any controlled-egress arrangement and train staff on release. Do not let lockdown override egress. Keep as-built drawings, test records, and a hardware schedule; a standard across 60 doors is useful only if it meets each door's fire rating, egress, and ADA requirements.
