Regarding Fire Alarm Systems, consider the following:1.Addressable fire alarm systems can pinpoint the exact location of the triggered detector.2.Ionization smoke detectors are generally preferred for kitchen areas to avoid false alarms.3.Manual call points (MCPs) allow occupants to manually initiate a fire alarmWhich of the statements given above is/are correct?

Correct Answer: C - 1 and 3 only

Quick Concept Explanation

Addressable fire-alarm systems assign an identity/address to each detector or module, enabling the panel to locate the initiating device. Kitchens are prone to nuisance alarms from cooking aerosols, so detector selection is application-specific and heat detection is often preferred over a sensitive ionization smoke detector.

Exam focus: Choose detector type for the environment, not just sensitivity. Common trap: Ionization smoke detectors are not generally the preferred kitchen solution for avoiding false alarms.

Statement-wise Verification

• Statement 1 - Correct.
  Addressable fire alarm systems can pinpoint the exact location of the triggered detector.
  Addressable fire-alarm systems assign an identity/address to each detector or module, enabling the panel to locate the initiating device.
• Statement 2 - Incorrect.
  Ionization smoke detectors are generally preferred for kitchen areas to avoid false alarms.
  The correct principle is: Kitchens are prone to nuisance alarms from cooking aerosols, so detector selection is application-specific and heat detection is often preferred over a sensitive ionization smoke detector.
• Statement 3 - Correct.
  Manual call points (MCPs) allow occupants to manually initiate a fire alarm
  Manual call points provide deliberate human initiation.

Core Concept

Addressable fire-alarm systems assign an identity/address to each detector or module, enabling the panel to locate the initiating device. Manual call points provide deliberate human initiation. Kitchens are prone to nuisance alarms from cooking aerosols, so detector selection is application-specific and heat detection is often preferred over a sensitive ionization smoke detector.

Formula / Key Relationship

Addressable loop → device-level identification.

Why the Other Options Are Wrong

Option A is incorrect because it includes incorrect statement(s) 2 and omits correct statement(s) 3. Option B is incorrect because it includes incorrect statement(s) 2 and omits correct statement(s) 1. Option D is incorrect because it includes incorrect statement(s) 2.

Exam Shortcut / Approach

Choose detector type for the environment, not just sensitivity.

Common Mistake

Ionization smoke detectors are not generally the preferred kitchen solution for avoiding false alarms.
