answer

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.
question

Fire Protection System
answer

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.
question

Impairment Coordinator
answer

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.
question

Initiating Device
answer

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.
question

question

Plenum
answer

The open space that carries air between the ceilings and floor above.
question

Protected Premises
answer

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.
question

Single-Station Smoke Alarm
answer

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.
question

Smoke Alarm
answer

A single – or multiple- station alarm responsive to smoke and not connected to a fire alarm system.
question

Smoke Detector Maintenance Company Certificate
answer

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.
question

Trouble Signal
answer

A signal initiated by the fire alarm system or device indicative of a fault in a monitored circuit or component.
question

Unnecessary Alarm
answer

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.
question

Unwarranted Alarm
answer

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.
question

Supervisory Signals
answer

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.
question

Lamp Test
answer

This function is used on some FACP’s to check the condition of the light emitting diodes (LEDs) on the FACP.
question

Remote Annunciator Panel
answer

When installed shall function for visual notification of alarm, supervisory or trouble conditions only.
question

Addressable System Smoke Detectors
answer

Provide an alarm indication to a control unit. In addition, they also signal the location of the alarm.
question

Intelligent System Smoke Detectors
answer

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.
question

Smoke Detectors with Control Output Functions
answer

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.
question

Smoke Dampers
answer

Open and close when required to provide fresh air or to stop smoke passage.
question

Fire Dampers
answer

Close when a rise in temperature occurs and stay shut to stop fire from passing through a barrier.
question

Rate-of-Rise Heat Detectors
answer

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.
question

Fixed-Temperature Heat Detectors
answer

Activate the alarm when the detector components melt at a preset temperature level. Normally require replacement after they have sounded an alarm.
