“All buildings or parts of buildings served by an internal automatic fire detection or suppression system, having a connection to a central monitoring station facility, shall be provided with a key lock box approved prior to installation by the city fire department.”
Of all the hundreds of commercial buildings we did, not one did we install the fire sprinkler shutoff inside the building, always outside where it was accessable to the fire department.
If there were automatated access gates a fire department lock box was provided to the automated gates only.
You are right that is typical. Were you in the fire suppression business?
