1. 1While identifying devices for inspection, a technician views an ES-50X System Point display that shows SMOKE (PHOTO). What type of device is identified?

   1. A. A photoelectric smoke detector
   2. B. An ionization smoke detector
   3. C. A fixed-temperature heat detector
   4. D. A sprinkler waterflow monitor

   Answer: A

   Explanation: The manual identifies "SMOKE (PHOTO) - the device type which is a photoelectric smoke detector (could also be ION for ionization smoke detector)". Thus this point identifies a photoelectric detector, rather than another sensing technology or a monitor module.

   Reference: Fire-Lite ES-50X Series Manual — Section 4.23.1, System Point, p.116

2. 2Which observation matches the normal condition specified on the ES-50X operating sheet?

   1. A. Green AC POWER and yellow TROUBLE on; SYSTEM NORMAL displayed
   2. B. Only green AC POWER on; SYSTEM NORMAL displayed
   3. C. Green AC POWER and yellow DISABLED on; SYSTEM NORMAL displayed
   4. D. All front-panel indicators off; SYSTEM NORMAL displayed

   Answer: B

   Explanation: The operating sheet specifies, "NORMAL - Only AC POWER is illuminated green. All other indicators are off. LCD display will read SYSTEM NORMAL." Additional yellow indicators or absence of the AC indicator do not match that complete normal indication.

   Reference: Fire-Lite ES-50X Series Manual — Operating Instructions, Normal, p.165

3. 3During an ES-50X alarm test, what does the first press of Acknowledge do to the panel's piezo sounder?

   1. A. It changes the piezo to the evacuation pattern
   2. B. It silences the panel's piezo sounder
   3. C. It increases the piezo output for the next event
   4. D. It defers silencing until the initiating device clears

   Answer: B

   Explanation: The manual states, "The first press of the Acknowledge key silences the piezo sounder". This acknowledgment acts on the local sounder; it does not require the initiating condition to clear first.

   Reference: Fire-Lite ES-50X Series Manual — Section 4.1.1, Acknowledge, p.107

4. 4An installed battery's original ELK-BLT Version 3.0 baseline is 400 Mhos. At the reference temperature, what is the highest current reading at or below which the manufacturer's 71%-of-baseline replacement guidance applies?

   1. A. 116 Mhos
   2. B. 284 Mhos
   3. C. 324 Mhos
   4. D. 400 Mhos

   Answer: B

   Explanation: The instructions state, "If the Mhos has declined to 71% or lower from the baseline Mhos reading the battery should be replaced." The boundary is 400 × 0.71 = 284 Mhos. The value 116 is the 29% decline amount, and 324 corresponds to the separate 81% weak reference.

   Reference: ELK-BLT Battery LifeTester Version 3.0 Instructions — Instructions, step 4b, p.2

5. 5An ES-50X detector record displays 1D023. When matching the record to the device inventory, what does 023 identify?

   1. A. The assigned software zone
   2. B. The detector's SLC address
   3. C. The number of installed detectors
   4. D. The signaling line circuit number

   Answer: B

   Explanation: The manual explains "1D001 - 1 = SLC Loop, D = Detector, 001 = Address 001". Thus 023 is the address; the initial 1 identifies the loop, and the suffix is not the software zone or a detector count.

   Reference: Fire-Lite ES-50X Series Manual — Section 4.23.1, System Point, p.116

6. 6During inspection of an ES-50X, the yellow Disabled LED is flashing. What condition does this identify?

   1. A. A detector has reached its smoke sensitivity threshold
   2. B. The panel has lost its primary AC power source
   3. C. An alarm signal has failed to reach the central station
   4. D. A zone, NAC, detector, or module has been disabled

   Answer: D

   Explanation: Under Disabled, the manual states, "This is a yellow LED that flashes to indicate that a zone, NAC, detector or module has been temporarily disabled in programming by the user." It identifies a programmed disablement, rather than an alarm, AC loss, or communication failure.

   Reference: Fire-Lite ES-50X Series Manual — Section 4.2, LED Indicators—Disabled, p.108

7. 7During the ES-50X lamp test produced by releasing Reset, which LED is EXCLUDED from the all-LED test?

   1. A. The Battery LED
   2. B. The Fire Alarm LED
   3. C. The Communication LED
   4. D. The Ground LED

   Answer: D

   Explanation: The Reset description specifies "all LEDs (except the Ground LED), piezo sounder and LCD display segments". The exclusion is the Ground LED, not Battery, Fire Alarm, or Communication.

   Reference: Fire-Lite ES-50X Series Manual — Section 4.1.4, Reset, p.107

8. 8When replacing a two-battery Yuasa series string, battery 1 positive is connected to the charger/load positive. What interbattery connection follows the manufacturer's single-string instructions?

   1. A. Battery 1 positive to battery 2 positive
   2. B. Battery 1 negative to battery 2 negative
   3. C. Battery 1 positive to battery 2 negative
   4. D. Battery 1 negative to battery 2 positive

   Answer: D

   Explanation: Yuasa instructs, "Connect the negative terminal (-) of battery #1 securely to the positive terminal (+) of battery #2." With the stated positive termination fixed, this is the specified series interconnection, rather than a parallel connection or reversed sequence.

   Reference: Yuasa Battery Installation, Commissioning & Maintenance Guide — Section 4.2, Single string battery connection—Intercell connections

9. 9Unwanted detector alarms began after building electrical equipment was changed. Under System Sensor's guidance, how broadly should the building manager's equipment-change history be reviewed for this investigation?

   1. A. Review changes only to the fire alarm equipment
   2. B. Review changes only to devices already reporting alarms
   3. C. Review all equipment changes around the alarm-pattern onset
   4. D. Review changes only to the central-station communicator

   Answer: C

   Explanation: The guide says "all equipment changes made in the building immediately prior to or concurrent with the beginning of the development of the alarm pattern should be reviewed." Limiting the history to alarm equipment or already alarming devices can exclude other electrical or electromechanical changes causing interference.

   Reference: System Sensor System Smoke Detectors Applications Guide — Effects of Other Systems on Alarm System, p.15

10. 10What does a flashing yellow Maintenance LED on an ES-50X indicate?

    1. A. A detector needs cleaning or replacement because of its chamber reading or drift
    2. B. A detector is temporarily disabled because its zone was removed from service
    3. C. A detector is in alarm because its programmed verification delay has expired
    4. D. A detector has lost AC power because its dedicated branch circuit has opened

    Answer: A

    Explanation: The Maintenance LED "flashes to indicate that a smoke detector requires cleaning or replacement due to an invalid chamber reading or excessive drift." This is a maintenance indication, not the panel indications for disablement, alarm, or power loss.

    Reference: Fire-Lite ES-50X Series Manual — Section 4.2, LED Indicators—Maintenance, p.108
