With Verified Answers 2024

Which duties can an S-95 Certificate of Fitness holder perform? - ANS-Visual Inspections Only

• of fire alarm system components and smoke detectors What is the primary purpose of Fire Alarm Systems? - ANS-To warn building occupants and transmit signals indicating a fire condition to the Fire Department via central station. What is a Fire Alarm signal? - ANS-The signal initiated by a fire alarm initiating device such as a manual fire alarm pull station, smoke detector, water-flow switch, or any device in which their activation indicates presence of fire. What is a Supervisory Signal? - ANS-A signal indicating that a system or device being monitored has been compromised or is in an abnormal state.

What is an Acknowledge Switch (ACK)? - ANS-This switch/button is used to acknowledge alarm, supervisory, or trouble conditions. Why is an Alarm Silence Switch helpful after an evacuation - while the source of alarm is being investigated? - ANS-This switch/button silences audible and visual devices (sirens, bells, gongs) so it's easier for Emergency Responders to communicate. Which switch/button is pushed once an alarm condition is cleared? - ANS-The System Reset Switch Smoke Detectors should be cleaned not less than - ANS-Once every six months How often should Analog Smoke Detectors be cleaned? - ANS-One week from receipt of an indication that cleaning is needed. How often should Smoke Detectors be tested for smoke entry? - ANS-Not less than once a year After activation, which type of heat detector self-restores? Which type doesn't? - ANS-Fixed- Temperature heat detectors: Doesn't self - restore and requires replacement. Rate of Rise heat detectors: self-restore Fire Alarm Circuits' primary power source shouldn't generate electric power exceeding which voltage? - ANS-277/480 volts All abnormal conditions be investigated and noted where? - ANS-A bound Log Book Alarm Notification Appliance - ANS-A fire alarm system component (bell, light, etc.) that issues an audible, tactile, or visual alert. Annunciator - ANS-A unit containing one or more indicator lamps, alphanumeric displays, etc. in which each indication provides status info about a circuit, condition, or location. ARCS (Auxiliary Radio Communication System) - ANS-A wireless two-way building communication system for Fire Dept. use only. Accessibility - ANS-Admitting close approach- not guarded by locked doors, elevation, etc. Initiating Device - ANS-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. Nuisance Alarm - ANS-An alarm caused by mechanical failure, malfunction, improper installation, improper maintenance or an undetermined cause. Plenum - ANS-The open space that carries air between the ceilings and floor above.

Single-Station Smoke Alarm - ANS-One unit incorporating the detector, control equipment, and the alarm-sounding device - operated by power supply in the unit or obtained during installation. Smoke Alarm - ANS-A single-or-multiple-station alarm responsive to smoke and not connected to a fire alarm system. Trouble Signal - ANS-A signal initiated by a fault in a monitored circuit or component. Unnecessary Alarm - ANS-An alarm signal for which a fire department response is not necessary. Unwarranted Alarm - ANS-An alarm signal transmitted by a fire alarm system which failed to function due to improper installation/maintenance, malfunction, etc. AN APPROVED CENTRAL STATION COMPANY IS ONE THAT HAS BEEN ISSUED A VALID CERTIFICATE FROM ____________. - ANS-FDNY THE PRIMARY PURPOSE OF A ______________ IS TO PROCESS SIGNALS RECEIVED FROM INITIATING DEVICES AND TO ACTIVATE APPROPRIATE SIGNALS. - ANS- FIRE ALARM CONTROL PANEL A __________ SIGNAL INDICATES THAT THE ALARM SYSTEM, TRANSMITTER, OR COMMUNICATIONS PATH IS WHOLLY OR PARTIALLY OUT OF SERVICE. - ANS- TROUBLE THE FDNY IS NOT DISPATCHED TO RESPOND TO _________ OR ________ SIGNALS. - ANS-SUPERVISORY, TROUBLE DO NOT SILENCE THE BUILDING ___________ AND ________ DEVICE UNTIL THE FIRE ALARM CONDITION IS VERIFIED BY FDNY PERSONNEL. - ANS-AUDIBLE, VISUAL ________ SHALL NOT BE A SUBSTITUTE FOR CONNECTION TO A SECONDARY POWER SOURCE. - ANS-BATTERIES IONIZATION DETECTORS USE AN _______________ AND A SOURCE OF IONIZING - ANS-IONIZATION CHAMBER IONIZATION SMOKE DETECTORS MONITOR ___________, OR ELECTRICALLY CHARGED PARTICLES IN THE AIR. - ANS-IONS _____________ DETECTORS ARE BETTER AT SENSING SMOKY FIRES, SUCH AS THOSE CAUSED BY A SMOLDERING MATTRESS. - ANS-PHOTOELECTRIC PROJECTED BEAM-TYPE DETECTORS SHALL BE KEPT CLEAR OF __________ OBSTACLES. - ANS-OPAQUE
