2.4        Interface of Fire Alarm, Life Safety and Security Systems at BWI Marshall

2.4.1            BWI Marshall Fire Alarm System (Terminal)

A.     The BWI Airport has a Honeywell Fire Alarm system. All modifications to the fire alarm system shall match the existing system components and be compatible with the existing infrastructure. The specified Honeywell Fire Alarm system shall function, operate and be compatible with the existing BWI Marshall Fire Alarm system.

B.     All components of the fire alarm system shall be UL listed and/or FM approved.

C.      The Project Specifications shall require the following:

1.      Contract with Honeywell to provide all programming changes to the fire alarm system.

2.      Submit fire alarm shop drawings to the OFM for review and approval.

3.      Submit a hard copy of the as-built fire alarm shop drawings to the Office of the Fire Marshal for record purposes.

4.      Design and submit AutoCAD files of the fire alarm system floor plans to Honeywell to update the Fire Alarm Central Graphic Computer.

2.4.2            Access Controlled Egress Doors

A.     Access Control or Controlled Access Security System (CASS) is part of the Airport’s Integrated Access Security System (IASS).

B.     The following requirements shall apply to access controlled emergency egress doors. The consultant shall confirm any variance from this standard with MDOT MAA and FAA personnel.

1.      Magnetic locks shall be mounted to the top of door/frames. Only when clearance issues prohibit the use of mag-locks will the use of electric door strikes (electrified door hardware) be considered. Electric door strikes are not acceptable without the prior approval of the Office of the Fire Marshal.

2.      Provide panic hardware with door strike (this is not an electric door strike) and delayed egress magnetic locks that provide local alarm upon being activated and provide alarm to the BWI Marshall Dispatch upon activation of the non-reversible release countdown.

3.      Provide IASS system components. They are typically the door controller, combination card reader/keypad, door status contacts, audio/visual device and the door-locking device (mag-lock). Configure the system as follows:

a.      IASS shall release the mag-lock for all personnel who use the combination card reader/keypad. This is an approved non-emergency egress.

b.      The mag-lock will not release until a preset delay has expired. Pushing on the panic hardware for more than three (3) seconds starts the delay countdown.

c.      In the event of an emergency, occupants will push on the panic hardware, the local alarm will immediately sound, an alarm will be sent to the BWI Marshall Dispatch and the delay countdown will begin. When the delay has expired, the audio/visual device will sound, the mag-lock will release and the IASS will alert the police and the BWI Marshall Dispatch of the alarm condition. The security system audio/visual device shall be coded differently from the fire alarm system audio/visual device.

d.      The delay on release should be set to 15 seconds.

4.      Signage shall be placed on each egress door, stating “EMERGENCY EXIT ONLY”. Delayed egress doors shall be additionally equipped with signage stating “PUSH UNTIL ALARM SOUNDS, DOOR CAN BE OPENED IN 15 SECONDS”.

5.      The upper level emergency egress stairwell door in all holdrooms will be the secured door (with IASS). Only approved exceptions will allow the secured door to be on the lower level (ramp level). The consultant, MDOT MAA Security and the tenants shall decide which stairs will be utilized by airline personnel who may not have a BWI Marshall Security Badge, but need access to lower level operations areas.

6.      The door control microprocessor shall be provided with a battery backup power supply.

7.      All door status contacts are to be interfaced with the door control panel that is designed to send an immediate local and a remote alarm of unauthorized access to the Dispatch Center (DC). The panel is to be interfaced with the local door control microprocessor that is designed to send an immediate local and a remote alarm of unauthorized access with a local reset. The microprocessor is to be interfaced with the keypad/card reader access device and the secure side magnetic lock release device and be designed to distinguish the difference between an authorized and unauthorized access.

8.      All electronic panic hardware (crash bars) devices are to be directly wired to the magnetic lock to minimize chance of malfunction.

9.      All magnetic locks and access control electronics are to be on dedicated circuits and connected to a dedicated panel.

10.   Where egress doors are used in conjunction with operations, the release function from the secured side shall be coordinated with and approved by MDOT MAA Security.

Emergency Egress During Fire Alarm Activation Conditions

(Controlled Access Security Systems-Based Systems Only)

Emergency Egress During Non-Fire Alarm Activation Conditions

(Controlled Access Security System-Based Systems Only)

2.4.3            Elevators

Elevators shall be interconnected with the fire alarm system to initiate Phase I and Phase II recall. Heat detectors shall be used for shunt trip when necessary. All elevators shall be equipped with a flow switch for zoning/indicting purposes.

2.4.4            Building Automation Systems

Mechanical systems used for smoke management, purge and/or control shall be interconnected with the fire alarm system. Duct detectors and smoke dampers shall be interconnected with the fire alarm system.

Fire dampers are not required to be tied into the fire alarm system.

2.4.5            Public Address Systems

The public address system is not interconnected with the fire alarm system.

2.4.6            Sprinkler/Special Hazard Systems

Sprinkler and Special Hazard systems shall be interconnected to the fire alarm system to monitor alarm, supervisory, and trouble signals.
