For systems employing relocation or partial evacuation, a _______ or _______ pathway survivability shall be required for in-building pathway survivability Level 2 Level 3 Central station service, which consists of the following elements: Runner service The central station service elements shall be provided under contract to a subscriber by a ________ that has a listing for central station fire alarm services prime contractor The central station shall have not less than ______ qualified operators on duty at the central station at all times to ensure disposition of signals in accordance with the requirements of 26.3. two Complete records of all signals received shall be retained for at least ________. 1 year
The protected property shall be either a contiguous property or noncontiguous properties under one ownership. Proprietary Supervising stations Drawings which have been approved by the AHJ for a fire alarm project are commonly referred to as _____ drawings? Shop A project requires photoelectric spot type smoke detectors. Which of the following environmental conditions typically will affect photoelectric smoke detector response? Humidity greater than 93% Consider a Group M where the entire building is one-story at the level of exit discharge. A fire alarm system is required when the occupant load is _____ or greater? 500 Consider the use of smoke detectors on a level ceiling with beams where the ceiling height is 10 feet AFF. For a beam depth of less than _____ inches smooth ceiling spacing shall be permitted? 12 An acceptable substitute for FPLP is _____? CMP
Mandatory requirement Consider a parallel circuit with total voltage of 24 VDC and the total current of 1 amps. The circuit has two resistors of equal value. The value of each resistor is _____ ohms? 48 Which of the following is not true regarding OSHA restrictions on the use of extension cords? Extension cords shall be no longer than 50 feet The document that provides the chemical and first-aid information for a cleaning spray is the _____? Safety data sheet The fire alarm system requirements for a Use Group E with an occupant load of 75 are _____? A manual fire alarm system with visible notification appliances A NAC circuit is disconnected from the fire alarm control unit and the loop resistance is measured. The notification appliances are still connected to the circuit. The meter shows the loop resistance is correct. The polarity of the meter leads is switched, and the resistance is measured again. This reading indicates a very low resistance close to zero ohms. This would indicate _____? There is a diode in the loop Total resistance of two or more resistors wired in series is _____? Additive
Consider the installation of a visible notification appliance in a corridor which is 15 feet wide. Visible notification appliances shall have a spacing not to exceed _____ feet in a corridor? 100 While at a site visit to a correctional facility, it is determined that the general fire alarm signal requires human intervention to be initiated. This is permitted using a _____ feature? Pre Signal Consider the use of a visible appliance in a sleeping area. The distance from the top of the lens to the ceiling is 18 inches. Based on this, the minimum intensity of the visible appliance is _____ candela? 177 The fire alarm system design requires the installation of heat detectors in a 100' x 150' open room with a smooth and level ceiling 16 feet high (AFF). The heat detectors are listed for 50 foot spacing. How many heat detectors are required? 12 Consider a fire alarm circuit which has a wire run of 250 feet (500 feet of total wire). According to the system design, the circuit is required to maintain no more than 5 ohms resistance on the wire. The circuit conductors are stranded coated copper. Based on this the appropriate minimum wire size is _____ AWG? 18 Consider a room which is 60 feet x 120 feet with a smooth and level ceiling at 10 feet AFF. A total of _____ projected beam type smoke detectors are required to cover this area? 1
Less than the value of the smallest resistor Consider a PLFA system. The smallest conductor size permitted for multiconductor cable is _____ AWG? 26 An audible and visible notification appliance must be installed 500 feet from the fire alarm control unit. The manufacturer's data sheet states that there shall be not more than five ohms resistance between the control unit and the appliance. What is the smallest sized solid coated copper conductor that could be used for this application? 14 According to the IBC, activation of the duct smoke detector is not required to initiate a visible and audible _____ signal at a constantly attended location? (Select Three) Alarm Trouble Delinquency A contract requires that the project comply with NFPA 72 Chapter 26 section 4. Based on this, upon receipt of an alarm signal, the supervising station operator shall dispatch a runner to the alarm location to arrive within _____ after receipt of a signal? 2 hours Power limited fire alarm circuit conductors shall be separated by at least _____ inches from conductors of any electric light, power, class I, nonpower limited fire alarm, or medium power network powered broadband communications circuits unless special conditions have been met?
Consider a parallel circuit. Current in parallel is _____? Additive Consider a 24 VDC notification appliance circuit where 10 devices are wired in parallel. The total current draw for the circuit is 1 amp. The circuit consists of 1,000 feet (total copper conductor) of solid, coated 18 AWG FPL. Assume a conductor temperature of 75 degrees Celsius. The voltage present at the last device is _____ volts?
Consider the use of heat detectors on a ceiling with solid joists. Heat detectors shall be mounted _____? At the bottom of the joists
