TFM 12 FIRE ALARM TECHNICAL
COMPREHENSIVE STUDY GUIDE 2026
FULL QUESTIONS AND SOLUTIONS
GRADED A+
◍ Digital Alarm Communicator System (DACS).
Answer: A system in which signals are transmitted from a digital alarm
communicator transmitter (DACT) located at the protected premises through
the public switched telephone network to a digitalalarm communicator
receiver (DACR). (SIG-SSS)
◍ Double Doorway.
Answer: A single opening that has no interveningwall space or door trim
separating the two doors. (SIG-IDS)
◍ Delinquency Signal.
Answer: A signal indicating the need for action in connection with the
supervision of guards or system attendants. (SIG-PRO)
◍ Guard's Tour Supervisory Signal.
Answer: A supervisory signal monitoring the performance of guard patrols.
(SIG-PRO)
◍ Radio Alarm System (RAS).
Answer: A system in which signals are transmitted from a radio alarm
transmitter (RAT) located at a protected premises through a radio channel to
two or more radio alarm repeater station receivers (RARSR) and that are
annunciated by a radio alarm supervising station receiver (RASSR) located
at the central station. (SIG-SSS)
◍ Flame.
, Answer: A body or stream of gaseous material involvedin the combustion
process and emitting radiant energy at specific wavelength bands
determined by the combustion chemistry of the fuel. In most cases, some
portion of the emitted radiant energy is visible to the human eye. (SIG-IDS)
◍ Guard's Tour Reporting Station.
Answer: A device that is manually or automatically initiated to indicate the
route being followed and the timing of a guard's tour. (SIG-IDS)
◍ Textual Visible Notification Appliance.
Answer: A notification appliance that conveys a stream of visible
information that displays an alphanumeric or pictorial message. Textual
visible notification appliances provide temporary text, permanenttext, or
symbols. Textual visible notification appliances include, but are not limited
to, annunciators, monitors, CRTs, displays, and printers. (SIG-NAS)
◍ Smooth Ceiling.
Answer: A ceiling surface uninterupted by continuous projections, such as
solid joists, beams, or ducts, extending more than 4 in. (100 mm) below the
ceiling surface. (SIG-IDS)
◍ Smoke Detector.
Answer: A device that detects visible or invisible particles of combustion.
(SIG-IDS)
◍ Type B Public Emergency Alarm Reporting System.
Answer: A system in which an alarm from an alarm box is automatically
transmitted to fire stations and, if used, is transmitted to supplementary
alerting devices. (SIG-PRS)
◍ Private Operating Mode.
Answer: Audible or visible signaling only to those persons directly
concerned with the implementation and direction of emergency action
initiation and procedure in the area protected by the fire alarmsystem.
(SIG-NAS)
◍ Radiant Energy-Sensing Fire Detector.
, Answer: A device that detects radiant energy, such as ultraviolet, visible, or
infrared, that is emitted as a product of combustion reaction and obeys the
laws of optics. (SIG-IDS)
◍ Multi-Criteria Detector..
Answer: A device that containsmultiple sensors that separately respond to
physical stimulus such as heat, smoke, or fire gases, or employs more than
one sensor to sense the same stimulus. This sensor is capableof generating
only one alarm signal from the sensors employed in the design either
independently or in combination.The sensor output signal is mathematically
evaluated to determine when an alarm signal is warranted. The evaluation
can be performed either at the detector or at the control unit. This detector
has a single listing that establishes the primary function of the detector.
(SIG-IDS)
◍ Trouble Condition.
Answer: An abnormal condition dueto a fault in a portion of a system
monitored for integrity. (SIG-FUN) [ROP-29]
◍ Open Area Detection (Protection).
Answer: Protection of an area such as a room or space with detectors to
provide early warning of fire. (SIG-IDS)
◍ Proprietary Supervising Station Service.
Answer: The use of a system or a group of systems including the protected
premises fire alarm system(s) in which the operations of circuits and devices
are signaled to, recorded in, and supervised from a supervising station under
the same ownership as the protected premises that has competent and
experienced operators who, upon receipt of a signal, take such action as
required by this Code. Related activities at the protected premises, such as
equipment installation, inspection, testing, maintenance, and runner service,
are the responsibility of the owner. Proprietary supervising station service is
controlled and operated by the entity whose properties are the protected
premises. (SIG-SSS)
◍ Loss of Power.
