a. Terminal Building - all areas will be zoned as either a public area or a tenant area.

b. Public areas shall have visual appliances (strobe lights) and audible appliances (horns). Emergency announcements shall come from terminal-wide public address (PA) system. In the event of a failure of the PA System, horns will be activated manually from the BWI Marshall Dispatch. All appliances in this zone, horns and strobes, shall be activated separately via manual control from the BWI Marshall Dispatch. Horns shall be silenced during PA System announcements without silencing the strobes. Upon completion of announcements, the horns shall reactivate.

c. Tenant areas shall have audio/visual (horn/strobe) notification. Publicly accessible portions of tenant spaces shall have PA speakers for emergency announcements as noted above. All appliances in this zone shall be automatically activated by the associated FS-90 FACP or the XLS panels.

2. Remote Annunciators shall not be provided unless otherwise required by the Office of the Fire Marshal.

3. EBI Central Color Graphic Computers shall be programmed and updated as required by expansions and modifications to the Fire Alarm. System. Cost of programming and computer upgrades shall be included in the construction project along with associated construction costs.

Addressable Interface Units (monitoring modules) shall be used to monitor indicating devices that are not otherwise equipped for multiplexed addressable communication such as sprinkler valve tamper switches.

1. Manual Pull stations shall be addressable double action type without glass rod inserts. Provide waterproof Lexan covers on pull stations located outdoors and in parking garages.

2. All surface mounted smoke detectors shall be addressable photoelectric type. Ionization type detectors are not permitted.

4. Heat Detectors shall be addressable combination rate of rise and fixed temperature type within air-conditioned spaces.

5. Pressure Switches for pre-action systems, shall be supplied with addressable monitoring modules.

6. Water Flow Switches for sprinkler systems, shall be supplied with addressable monitoring modules for alarm conditions.

7. Fire Extinguishing System Control Panels for fire suppression systems (such as carbon dioxide systems, clean agent, foam systems, etc.) shall be supplied with addressable monitoring modules.

Special provisions for exhausting noxious or hazardous atmospheres shall be designed on a per project basis. The design shall utilize HVAC systems and controls; zoning strategies and supplemental exhaust.

A. The Office of the Fire Marshal is the local Authority Having Jurisdiction for MDOT MAA owned facilities. The Consultants must coordinate with the Office of the Fire Marshal during the design of fire detection and alarm systems. Submit relevant drawings and specifications to MDOT MAA FDE for transmittal to the Office of the Fire Marshal for review at each required submission. At a minimum MDOT MAA recommends meeting with the Office of the Fire Marshal prior to 50% completion of design. General requirements of the Office of the Fire Marshal include, but are not limited to, the following:

B. The Fire Detection and Alarm System shall comply with the following requirements:

c. Only copper conductors shall be used. Conductor wire shall be solid. Stranded conductors will not be allowed. The only exception allowed for stranded wire will be for the installation of speakers in a fire alarm controlled voice evacuation system.

a. Initiating circuits shall be a minimum of No. 14 AWG twisted pair. No. 16 AWG may be used, if pre-approved by the Office of the Fire Marshal, for initiating circuits, depending on electrical system design and manufacturer's requirements. No. 18 AWG shall not be permitted.

a. All fire alarm wiring shall be in conduit complying with applicable NEC articles. (Exception: Existing speaker wiring which serves as part of the PA portion of the fire alarm system may remain as presently installed, without conduit, unless an area is renovated to an extent that the Office of the Fire Marshal determines that encasement in conduit is required.)

6. Identification of conduit and junction boxes will be done with red paint and wording that clearly identifies the installation as being a fire alarm system. Panel Connections:

a. Shall be on the left hand or right hand sides. No connections shall be done from the bottom.

b. Top mount connections shall be permitted only if waterproof connectors are used.

a. All fire alarm systems shall be provided with a primary and a secondary power supply.

b. Secondary power shall automatically supply the energy to the system within 30 seconds. Secondary power shall be from a storage battery capable of operating the complete alarm system in normal or supervisory (non-alarm) mode for a period of 24 hours and at the end of this period, have sufficient capacity to operate the system, including alarm indicating devices in either alarm or supervisory mode for a period of 15 minutes. This requirement applies to new panel installations and any existing panels affected by renovation work.

d. An engine-driven generator with automatic transfer switch arranged in accordance with NFPA 72 may be used for secondary power in lieu of storage batteries.

b. Shop drawings shall include a floor plan showing the location of the fire alarm panel.

c. Fire alarm system zones shall follow fire protection sprinkler zones as appropriate.

C. All duct type smoke detectors shall be provided with remote test switches and indicator lights with identification signage. The test switches shall be readily accessible and have readily visible (below ceiling) indicators. Smoke detectors shall be provided with two sets of contacts. One set for alarm and one set to shut down related HVAC equipment. All duct detectors shall be accessible for inspection, maintenance, repair and replacement.

D. All sprinkler water flow, switches and tamper switches shall be connected to the fire alarm system.

E. The Honeywell EBI Graphical Central Computer shall be programmed with a specific designation of the alarm location (for example, boarding bridge gate number or other geographic locator).

F. Install a dedicated MDOT MAA "IN-HOUSE" telephone adjacent to all fire alarm control panels (FACP). This requirement applies to new panel installations and any existing panels affected by renovation work. Design shall include an empty conduit between the proposed telephone location and the nearest telephone closet. Coordinate with MDOT MAA Telecom Section for MDOT MAA to install the telephone

G. YOU ARE HERE" designation and the egress paths clearly shown on a floor plan. Permanent signage, with the capability for changing inserts, shall be specified to be included in the construction contract. See Chapter 2.3.1 Terminal Evacuation Plans. Provide a floor plan submittal showing the proposed locations of the evacuation plans(s) for approval by the Office of the Fire Marshal.

H. Signs shall have red lettering and a white background encased or enclosed in an approved box. Provide directional exit signs in the main corridor of the concourses (piers) to direct occupants to the exit stairs along the exterior holdroom walls.
