TFM 12 Texas Fire Alarm Technical Exam (Actual
Exam 2026) | All Questions and Correct Answers |
Verified Answers | Newest Version
What is the maximum voltage permitted through multi-conductor N.P.L.F.A
cables? ---------CORRECT ANSWER-----------------150 volts
What is the voltage rating marked on P.L.F.A cables? ---------CORRECT ANSWER-----
------------Not less than 300 volts
Shall the voltage rating marked on P.L.F.A cables? ---------CORRECT ANSWER--------
---------No, because they may be mistakenly used for electrical applications.
What is 'Rate Compensation Detector'? ---------CORRECT ANSWER-----------------A
device that responds when a temperature rises at an exceeding rate that is
predetermined.
What is a 'Smoke Detector'? ---------CORRECT ANSWER-----------------a device that
detects both visible and invisible combustion particles?
,Which detector is best a detecting invisible particles? ---------CORRECT ANSWER----
-------------Ionization
Which sensor is better at detecting thick, visible smoke particles? ---------CORRECT
ANSWER-----------------Photoelectric
What is a SPOT TYPE sensor? ---------CORRECT ANSWER-----------------a device in
which detecting an element is concentrated at a particular location.
What is a DIGITAL ALARM COMMUNICATOR TRANSMITTER ( D.A.C.T)? ---------
CORRECT ANSWER-----------------A system component at the protected premises is
connected to the detection devices. It has a line seizure and can connect to a
D.A.C.R.
What is a DIGITAL ALARM COMMUNICATOR RECEIVER? (D.A.C.R)? ---------
CORRECT ANSWER-----------------A system component that accepts and displays
signals sent over the public phone network from a D.A.C.T (i.e A.D.T monitoring
center)
What is an alarm signal? ---------CORRECT ANSWER-----------------A signal indicating
an emergency that requires immediate action.
, What is a Supervisory signal? ---------CORRECT ANSWER-----------------A signal that
indicates the need for action in connection with the SUPERVISION of fire
equipment.
What is a Trouble signal? ---------CORRECT ANSWER-----------------A signal that
indicates a fault with the fire equipment. It must have an audible signal,
distinctive from alarm signals.
Does an exterior harm for a sprinkler system need to be supervised? ---------
CORRECT ANSWER-----------------Yes
What is a Cloud Chamber Smoke detection? ---------CORRECT ANSWER----------------
-A detector draws an air sample into a high humidity, low pressure chamber. The
conditions in the chamber cause the moisture in the air to condense on the
smoke particles, forming a cloud. The density of this cloud is measured by a
photoelectric principle, if it meets a certain criteria, an alarm is generated.
What is an Ionization Smoke detector? ---------CORRECT ANSWER-----------------A
detector that used a small amount of radio active material to ionize the air
between two differently charged electrodes. When smoke is present between
these electrodes, it causes the conductance of the air to decrease, and this causes
the alarm to trip.
