Can the property front desk share a phone number with the fire control room?

You can't. The fire control room is not shared with the duty room, guard, reception room, etc. According to Article 3.4.6 of Code for Design of Automatic Fire Alarm System (GB50 1 16 to 20 13): "It is strictly forbidden to pass through electrical lines and pipelines unrelated to fire control facilities in the fire control room."
