notifications from the central station company concerning the status of the protective
signaling system at the protected premises and who is authorized to take action with
respect to such system.
Fire Alarm Control Unit (FACP, FCS)
A system component that receives inputs from automatic and manual fire alarm devices
and is capable of supplying power to detection devices and transponders of off-
premises transmitters. The control unit is capable of providing a transfer of power to the
notification appliances and transfer of condition to relays of devices.
Fire Alarm Signal
A signal initiated by a fire alarm-initiating device such as a manual fire alarm box (pull
station), automatic fire detector, water-flow switch, or other device whose activation is
indicative of the presence of a fire or fire signature.
Fire Alarm System
Any system, including any interconnected fire alarm sub-system, of components and
circuits arranged to monitor and annunciate the status of fire alarm or supervisory
signal-initiating devices.
Fire Protection System
Approved devices, equipment and systems or combinations of systems used to detect a

Impairment Coordinator
The person responsible as designated by the owner for ensuring that proper safety
precautions are taken when a fire protection system is out of service.
Initiating Device
A system component that originates transmission of a change-of-state condition, such
as in a smoke detector, manual fire alarm box, or supervisory switch.
Smoke Detector Maintenance
Work, including but not limited to, repair, replacement, and service, performed to ensure
that equipment operates properly.
Shall
Indicates a mandatory requirement.
Nuisance Alarm
Any alarm caused by mechanical failure, malfunction, improper installation, or lack of
proper maintenance, or any alarm activated by a cause that cannot be determined.
Out Of Service System
A fire protection system that is not fully functional; or whose operation is impaired or is
otherwise not in good working order.
Plenum
The open space that carries air between the ceilings and floor above.
Protected Premises
, A building, occupancy or structure located in the city that is equipped with a fire alarm
system that transmits an alarm signal to the department or a central station that
monitors such system for the purposes of reporting fire alarms to the department,
whether or not the installation of such system on the premises is required by law.
Single-Station Smoke Alarm
An assembly incorporating the detector, the control equipment, and the alarm-sounding
device in one unit, operated from a power supply either in the unit or obtained at the
point of installation.
Smoke Alarm
A single - or multiple- station alarm responsive to smoke and not connected to a fire
alarm system.
Smoke Detector Maintenance Company Certificate
A certificate issued by the commissioner to a person engaged in the business of
performing smoke detector cleaning and testing, which authorizes such person to
engage in such business and supervise the performance of such cleaning and testing
by certificate of fitness holders.
Trouble Signal
A signal initiated by the fire alarm system or device indicative of a fault in a monitored
circuit or component.
Unnecessary Alarm
An alarm signal transmitted by a fire alarm system which functioned as designed, but for
which a department response proved unnecessary. An example is an alarm triggered by
smoke from a lit cigarette in a non-smoking area, when the presence of such smoke
does not implicate fire safety concerns.
Unwarranted Alarm
An alarm signal transmitted by a fire alarm system which failed to function as designed
as a result of improper installation, improper maintenance, malfunction, or other factor.
Example are alarms resulting from improper smoke detector placement, improper
detector setting for installed location, lack of system maintenance, and control panel
malfunction. It is important to know that the alarm verification feature reduces the
number of these alarms.
Supervisory Signals
Signals which Indicate that a system or device being monitored has been compromised
or is in an abnormal state. Will audibly and visually annunciate at the FACP to indicate
the condition needs to be investigated and corrected. The FACP will also send a signal
to an FDNY approved central station.
Lamp Test
This function is used on some FACP's to check the condition of the light emitting diodes
(LEDs) on the FACP.
Remote Annunciator Panel
When installed shall function for visual notification of alarm, supervisory or trouble
conditions only.
Addressable System Smoke Detectors
Provide an alarm indication to a control unit. In addition, they also signal the location of
the alarm.
