NICET Fire Alarm Tech Level 1 Practice Test # 10 © Ted Smith 2017

Instructions Be sure to place this presentation in Slide Show Mode if it is not already in that mode before proceeding The purpose of this drill is to help you improve your skill at finding answers to questions using the applicable fire codes and also to help increase your knowledge of the Fire Alarm codes. Each slide will contain a question. The question will remain in the screen for a period of 2 minutes. At the end of the two minutes, a notification will sound and the slide will transition to the next slide which will have the correct answer to the question. After 15 seconds the next question will appear and the process will continue. During the test do not worry about the correct answers when those slide appear. You will be given an opportunity to review the answers with out the time at the end of the test. Click on the slide to start the timer and begin the test

answer A, B and D Inability to speak coherently is a symptom of a Stroke

NFPA 72 3. An entire room of emergency control interface devices for a Class A system may have the feed and return legs installed in the same raceway. This is permitted in which of the following sized rooms? A. 15’ x 40’ B. 30’ x 90’ C. 20’ x 55’ D. None of the above

answer A. 15’x 40’ is 600 square feet Annex A A12.3.8.1(3) permits this type of installation in rooms that are less than 1000 square feet.

First Aid 4. A coworker has severely lacerated his hand and blood is spurting out of the wound. What is the first thing that you should do to provide first aid, besides call for medical help. A. Apply a tourniquet to the upper arm B. Apply direct pressure on the area of the cut C. Have them raise their hand below their heart D. Have them stand up to keep blood flowing

answer D T14.3.1

NFPA 72 17. All means of interconnecting equipment, devices and appliances and wiring connections of a signaling circuit shall be monitored for integrity of the interconnecting conductors so that the occurrence of a single open or ground fault condition is the signaling channel is automatically indicated within _______ seconds. A. 60 B. 90 C. 100 D. 200
