Current through Register 1531, September 27, 2024
A fire-fighter's smoke control panel for fire department
emergency response purposes only shall be provided and shall include manual
control or override of automatic control for mechanical smoke control systems.
The panel shall be located in a fire command center complying with Section 911
in high- rise buildings or buildings with smoke-protected assembly seating. In
all other buildings, the fire-fighter's smoke control panel shall be installed
in an approved location adjacent to the fire alarm control
panel. The fire-fighter's smoke control panel shall comply with Sections
909.16.1 through 909.16.3. [F]
909.16.1
Smoke control systems.
Fans within the building shall be shown on the fire-fighter's control panel. A
clear indication of the direction of airflow and the relationship of components
shall be displayed. Status indicators shall be provided for all smoke control
equipment, annunciated by fan and zone, and by pilot-lamp-type indicators as
follows: [F]
1. Fans,
dampers and other operating equipment in their normal
status-WHITE.
2. Fans,
dampers and other operating equipment in their off or closed
status-RED.
3. Fans,
dampers and other operating equipment in their on or open
status-GREEN.
4. Fans,
dampers and other operating equipment in a fault
status-YELLOW/AMBER.
909.16.2
Smoke control panel.
The fire-fighter's control panel shall provide control capability over the
complete smoke-control system equipment within the building as follows: [F]
1. ON-AUTO-OFF control over each individual
piece of operating smoke control equipment that can also be controlled from
other sources within the building. This includes stairway
pressurization fans; smoke exhaust fans; supply, return and exhaust fans;
elevator shaft fans and other operating equipment used or intended for smoke
control purposes.
2.
OPEN-AUTO-CLOSE control over individual dampers relating to
smoke control and that are also controlled from other sources within the
building.
3. ON-OFF or OPEN-CLOSE
control over smoke control and other critical equipment associated with a fire
or smoke emergency and that can only be controlled from the fire-fighter's
control panel.
Exceptions:
1. Complex systems, where
approved, where the controls and indicators are combined to
control and indicate all elements of a single smoke zone as a unit.
2. Complex systems, where
approved, where the control is accomplished by computer
interface using approved, plain English
commands.
909.16.3
Control action and priorities. The fire- fighter's control panel
actions shall be as follows: [F]
1. ON-OFF and
OPEN-CLOSE control actions shall have the highest priority of any control point
within the building. Once issued from the fire-fighter's control panel, no
automatic or manual control from any other control point within the building
shall contradict the control action. Where automatic means are provided to
interrupt normal, nonemergency equipment operation or produce a specific result
to safeguard the building or equipment (i.e., duct freezestats, duct smoke
detectors, high-temperature cutouts, temperature-actuated linkage and similar
devices), such means shall be capable of being overridden by the fire-fighter's
control panel. The last control action as indicated by each fire-fighter's
control panel switch position shall prevail. In no case shall control actions
require the smoke control system to assume more than one configuration at any
one time.
Exception: Power disconnects required by NFPA
70.
2. Only the AUTO
position of each three-position fire-fighter's control panel switch shall allow
automatic or manual control action from other control points within the
building. The AUTO position shall be the NORMAL, nonemergency, building control
position. Where a fire-fighter's control panel is in the AUTO position, the
actual status of the device (on, off, open, closed) shall continue to be
indicated by the status indicator described above. When directed by an
automatic signal to assume an emergency condition, the NORMAL position shall
become the emergency condition for that device or group of devices within the
zone. In no case shall control actions require the smoke control system to
assume more than one configuration at any one time.
