As defined in NFPA admitting close approach: not guarded by locked doors, elevation, and other effective means.
Alarm Notification Appliance
A fire alarm system component, such as a bell, horn, speaker, light, text display or vibration device that issues an audible, tactile, and/or visual alert.
A signal indicating an emergency requiring immediate action, such as a signal indicative of fire.
A unit containing one or more indicator lamps, alphanumeric displays, or other equivalent means in which each indication provides status information about a circuit, condition or location.
Approved Central Station Company
A central station company that has been issued a valid certificate of operation from FDNY.

Defined Fire Alarm System
A fire alarm system or any sub-system thereof that automatically transmits signals to the department or a central station and that is installed in premises which are required to have a fire alarm system.
A person or entity designated by the subscriber who shall be responsible for receiving 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 fire, activate an alarm, extinguish or control a fire, control or manage smoke and products of a fire or any combination thereof, including fire extinguishing systems, fire alarm systems, sprinkler systems and standpipe systems.
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.
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.
Indicates a mandatory requirement.
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.
The open space that carries air between the ceilings and floor above.
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.
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.
A signal initiated by the fire alarm system or device indicative of a fault in a monitored circuit or component.
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.
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.
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.
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.
Intelligent System Smoke Detectors
Send information about smoke conditions to the control unit. The detector indicates the location of the alarm and provides environmental change information to the panel.
Smoke Detectors with Control Output Functions
When smoke detectors are installed on an initiating device circuit an are used for controlling operation (fan shutdown or elevator recall) with other devices installed on the same circuit, the control function must perform correctly, even with all other devices on the circuit in an alarm condition.
Open and close when required to provide fresh air or to stop smoke passage.
Close when a rise in temperature occurs and stay shut to stop fire from passing through a barrier.
Rate-of-Rise Heat Detectors
Activate the alarm when the room temperature increases at a rapid rate. This type of detector is more sensitive and does not have to be replaced after it has activated the fire alarm.
Fixed-Temperature Heat Detectors
Activate the alarm when the detector components melt at a preset temperature level. Normally require replacement after they have sounded an alarm.
