| Electricity | The main electrical panels, along with the emergency generator, are located in the southwest corner of the building. This room, however, is accessed through the mechanical room in the southeast corner of the building on the Lower Level. Each floor has independant breaker panels which are located in the room just east of the center core restrooms. |

| Water | |
| Loading Dock Location | The loading dock on the Lower Level is underneath the atrium of the main building. A vehicle fire at the loading dock or a fire in the trash compactor on the loading dock could compromise the building. The building entrances on the lower level are isolated from the loading dock by a fire door with a fusible link, but inventory and supplies unloaded onto the dock could interfere with the operation of the door. |
Fire Command Room is located in the northeast corner of the center core, next to Stair 2. Features include: Fire Alarm Panel, Automatic Smoke Control Panel, Generator Annunciator, Fire Pump Annunciator, Elevator Annunciator and selection switch, Communications Panel for Firefighter phones and Building PA (addressable by floor), Key box, Magnetic Lock Override and reset, and a direct dial telephone. The key to access the Fire Command Room is located in both knox boxes. 24-hour on-site security also may have the room unlocked for you on arrival. Fire Command Room Telephone Number: (972) 233-6845 |
The fire alarm panel is located in the Fire Command Room. Each detection device is addressed and can be identified by the panel. Additional Fire Alarm Panel Annunciators can be found on the Lower Level just inside the loading dock and on the 1st floor next to the restrooms. |
There are 12 elevator cars, all of which operate on Phase 1 / Phase 2 fireman service. Elevator keys and Lunar Keys are located in the key box of the Fire Command Room. Every floor and every car has a lunar key opening and a firefighter communication jack. All shafts are pressurized when the building is in alarm. While the building is operating under emergency power, only one car from bank "P" and one car from bank "G" can be used. The car to be used in each of these banks is selected from a switch on the elevator annunciator panel in the Fire Command Room. P1 - P7: Passenger cars in the middle of the center core that serve floors 1 - 15. The elevator equipment is in the penthouse of the building and best accessed by Stair 2. G1 - G3: Passenger cars on the west side of the atrium adjacent to the parking garage. These cars serve the lobby of the building and all floors (B3 - L7) of the parking garage. The elevator equipment is in the Penthouse of the parking garage and is accessed by Stair 3. S1: Passenger/mail shuttle elevator located on the west side of the center core and opens only on the Lower Level and the 1st floor. The equipment room is on the Lower Level in a closet just behind the shuttle car. S8: Service Elevator which is accessed on the west side of the center core and serves all floors of the building (LL - 15). The elevator equipment is in the Penthouse of the building and best accessed by Stair 2. Cars are grouped in the following common shafts: Shaft 1: P1 - P4 Shaft 2: P5 - P7, S8 Shaft 3: S1 Shaft 4: G1, G2 Shaft 5: G3 |
Two stairwells in the building, both of which are pressurized while the building is in alarm. Stair 1 is accessed in the southwest corner of the center core and opens on every floor of the building (LL - 15). Stair 1 contains a class 1 standpipe, an access ladder with hatch to the roof, and firefighter communication jacks on each floor. On inspection, the roof hatch was not locked. The stairwell pressurization fan is located in the mechanical room on the Lower Level. Stair 2 is accessed in the northeast corner of the center core and opens on every floor of the building (LL - 15). Stair 2 contains a class 1 standpipe, stair access to the roof, firefighter communications jacks on each floor, and sprinkler floor isolation valves. On inspection, the door to the roof could be unlocked with a master key. Isolation valves are approxiamately 8 feet off the landing, requiring a short ladder to reach safely. The stairwell pressurization fan is located in the Northeast storage room on the Lower Level. Stair 3 serves only the parking garage and allows access to the roof of the parking garage and the elevator equipment room for elevator bank "G". |
All floors of the building except the Lower Level and 1st floor are magnetically locked and require one of three magnetic key cards to access under normal building conditions. Key rings in the key box in the Fire Command Room include magnetic key cards. Magnetic locks are released when the fire alarm panel is in alarm, or when the override key in the Fire Command Room is manually activated. |
The building and parking garage are both fully covered by sprinklers. Floor isolation valves for the building are located in Stair 2 and are approximately 8 feet above the landing. Pressure can be boosted by pressurizing either of the two fire department connections. Both FDC's include (3) 2-1/2" and (1) 5" connections. The automatic suppression system is designed to flow a number of sprinkler heads to cover 2070 square feet of space. The fire pump is located in the mechanical room in the Lower Level and is rated at 750 gpm. Fire Department Connections for the parking garage are next to the north vehicle entrance. |
Class 1 standpipes are located in both Stair 1 and Stair 2. Pressure can be boosted by pressurizing either of the two fire department connections. |
Smoke control panel is in the Fire Command Room. On alarm, the HVAC pressurizes the floors above and below the alarm and exhausts the floor in alarm. Each fan and damper can also be controlled manually. Stairwells are pressurized on alarm by fans in the Lower Level mechanical room and northeast storage room. Elevator shafts are pressurized by fans on top of the elevator penthouses. Each can be manually controlled from the smoke control panel in the Fire Command Room. |
Handsets are located in the Fire Command Room. Communication jacks are located in each elevator lobby, in each elevator car, on each floor of both stairwells, in elevator penthouse, in Fire Pump room, and in the emergency generator room. |
