  1. When inspecting a duct smoke detector during PM, what physical check is essential before testing?

    Answer: Confirm sampling tubes are clear, properly oriented, and undamaged

    Blocked or misaligned sampling tubes prevent smoke-laden air from reaching the sensing chamber, making the detector non-functional.

  2. A technician is testing a pull station and finds the cover glass is cracked. What is the appropriate PM response?

    Answer: Replace the pull station or cover glass before leaving the site

    A cracked cover compromises tamper protection and weatherproofing; the component must be replaced during the same visit.

  3. During PM on a burglar alarm system, the technician measures 12.8V on a 12V sealed lead-acid battery at float charge. This indicates:

    Answer: Normal float voltage for a fully charged 12V SLA battery

    A float voltage of approximately 13.5–13.8V is typical at the charger; 12.8V open-circuit indicates a fully charged SLA battery.

  4. Which of the following is the correct procedure when temporarily disabling a zone during maintenance to prevent false dispatches?

    Answer: Notify the monitoring station and place the zone on test mode before beginning work

    Notifying the central station and placing the zone on test prevents unnecessary emergency dispatches during maintenance activity.

  5. What is the purpose of exercising electromechanical relays during a PM inspection?

    Answer: To prevent contact oxidation and ensure reliable switching

    Cycling relays during PM clears oxidation from contacts that builds up from inactivity, ensuring dependable operation during emergencies.

  6. A carbon monoxide detector installed in a commercial building fails to respond to a CO span gas test during PM. What should the technician do?

    Answer: Replace the detector immediately

    A CO detector that fails functional testing must be replaced immediately because electrochemical sensing cells cannot be field-recalibrated.

  7. When conducting PM on a monitored alarm system, which step verifies the communication path to the central station is functional?

    Answer: Performing a full communications test transmission and receiving confirmation from the central station

    A confirmed test transmission from the central station is the only reliable verification that the entire communication path is operational.
