1For a new residential building subject to BYKHY Article 96, which height threshold triggers the automatic sprinkler requirement?

A.Bina yüksekliği exceeding 21.50 m

B.Yapı yüksekliği exceeding 51.50 m

C.Yapı yüksekliği exceeding 30.50 m

D.Bina yüksekliği exceeding 6.50 m

Explanation: Article 96 requires sprinklers in residences whose yapı yüksekliği exceeds 51.50 m. Yapı yüksekliği includes the total constructed storey heights, including basements, mezzanines and attic accommodation; it must not be confused with bina yüksekliği.

2A designer classifies an ordinary hotel accommodation area using BYKHY Annex 1/B. No special storage or hazardous process is present. Which listed hazard group applies?

A.Light Hazard solely because people sleep there

B.High Hazard Process solely because it is a hotel

C.Ordinary Hazard Group 1 (Orta Tehlike-1)

D.Ordinary Hazard Group 4 (Orta Tehlike-4)

Explanation: Annex 1/B lists hotels among Ordinary Hazard Group 1 uses. Classification must follow the actual use and fire load; a hotel kitchen, storage room or other special area needs its own evaluation.

3Which pair correctly states the new-building enclosed-car-park sprinkler triggers in BYKHY Article 96?

A.Total enclosed area above 1000 m², or more than 20 vehicles admitted by lift

B.Total enclosed area above 600 m², or more than 10 vehicles admitted by lift

C.Any parking on two basement levels, regardless of area or vehicle access

D.Total enclosed area above 2000 m², or any vehicle admitted by lift

Explanation: Article 96 specifies enclosed car parks exceeding 600 m² total area and enclosed car parks admitting more than 10 vehicles by lift. The 2000 m² threshold concerns mechanical smoke extraction, while existing-building sprinkler provisions must be checked separately.

4Which pair of height values appears in the BYKHY Article 4 definition of yüksek bina, in the order bina yüksekliği / yapı yüksekliği?

A.6.50 m / 21.50 m

B.21.50 m / 51.50 m

C.30.50 m / 51.50 m

D.21.50 m / 30.50 m

Explanation: The definition uses bina yüksekliği above 21.50 m and yapı yüksekliği above 30.50 m. Individual system requirements use their own height measures and thresholds, so this definition alone does not establish every sprinkler or pressurization obligation.

5A room protected by total-flooding gas suppression gains a new cable penetration. Which verification most directly addresses the risk that extinguishing agent will escape too quickly?

A.An enclosure integrity test and retention-time assessment using measured leakage

B.A cylinder weighing check alone

C.An electrical continuity test of the discharge circuit alone

D.A sound-pressure test of the evacuation alarm alone

Explanation: A door-fan enclosure integrity test measures leakage so the expected agent retention can be evaluated. Cylinder contents and functioning alarms remain necessary, but neither demonstrates that a changed enclosure will retain its design concentration for the required period.

6How does a suitable wet-chemical kitchen suppression agent help prevent a hot cooking-oil fire from reigniting?

A.By reducing oxygen throughout the room with an inert-gas discharge

B.By cooling the oil and forming a protective foam-like layer over its surface

C.By using dry powder whose main action is flame-chain interruption

D.By relying only on appliance fuel shutoff without applying agent to the oil

Explanation: Wet-chemical agents for cooking-oil hazards cool the fuel and form a surface layer that limits vapour release and reignition. The selected system must protect the actual appliances, hood and associated hazards under its approved design instructions.

7Which event is a sprinkler-zone waterflow switch intended to report to the fire alarm system?

A.Movement of an isolation valve away from its supervised position

B.Water movement consistent with an operating sprinkler or an equivalent test flow

C.Low gas pressure in a dry system before water enters

D.The start command sent to a smoke-exhaust fan

Explanation: A waterflow switch reports water movement in the sprinkler zone. A suitable retard can filter short surges; the switch detects flow rather than confirming the presence or exact location of a fire.

8An electric/pneumatic double-interlock pre-action system detects smoke, but sprinkler piping gas pressure remains normal. What should occur under its normal automatic release logic?

A.The valve fills the piping because detection alone is sufficient

B.The detection alarm operates, but the valve awaits the required loss of sprinkler-piping gas pressure

C.Every closed sprinkler opens electrically

D.The system disables its gas-pressure supervision until manually reset

Explanation: This double-interlock arrangement requires both detection and the specified loss of sprinkler-piping gas pressure before admitting water. Single-interlock and other pre-action arrangements have different release logic and must not be treated as equivalent.

9For a sprinkler with metric K-factor in L/min/bar^0.5, which formula gives flow Q in L/min from inlet pressure P in bar?

A.Q = K × P

B.Q = K × P²

C.Q = P / K

D.Q = K × √P

Explanation: Sprinkler discharge is calculated as Q = K√P with compatible units. Rearranging gives P = (Q/K)²; a K-factor expressed in US units cannot be used directly with metric pressure and flow.

10A metric K-80 sprinkler operates at 1.44 bar inlet pressure. What is its flow using Q = K√P?

A.96.0 L/min

B.115.2 L/min

C.66.7 L/min

D.80.0 L/min

Explanation: The square root of 1.44 is 1.20, so Q = 80 × 1.20 = 96.0 L/min. This is the discharge of the individual sprinkler at that pressure, not the total system demand.

MMO MTYT Fire Protection Installation: Suggested Study Strategy

1Keep units consistent in Q = K√P and Hazen-Williams calculations; use actual internal pipe diameter.

2Distinguish bina yüksekliği, yapı yüksekliği and stair-shaft height, and check whether new-building or existing-building provisions apply.

3Work complete sprinkler, cabinet/hydrant and pressurization projects in writing, including drawings and assumptions. These MCQs cover selected concepts and do not replace that practice.

Frequently Asked Questions

What is the structure of the official MMO MTYT examination?

The exam has two parts totaling 210 minutes: Part 1 consists of 20 written theory questions (30 minutes, 20 points), and Part 2 consists of 3 comprehensive written project design calculations (180 minutes, 80 points covering sprinklers, fire cabinets/hydrants, and stairwell pressurization).

What is the passing score and retake policy?

The minimum passing grade is 70/100. The PBK programme describes four examination opportunities within two years without an additional fee after failure, while branch notices state a maximum of four examination rights. Confirm how prior attempts are counted with your PBK examination centre.

What materials and tools are permitted during the official exam?

The PBK programme lists pencils, erasers, sharpeners, a scientific calculator, calculation tables and formulas, drawing tools, course notes and books. Follow the examination centre's instructions about permitted use in each section. Phones and other unlisted electronic devices are not included in this permission.

Does this bank reproduce the official assessment or confirm an English-language sitting?

No. These are independent English-language MCQ study questions for selected MTYT topics. The official assessment includes full written project problems, and the public scheme does not publish an assessment-language list. PBK says it does not provide interpreters for candidates who cannot understand the examination language; ask the centre about delivery and response languages.
