An FSCI update from Keith S. Frangiamore, President
A Fire Safety Consultants, Inc. celebration!
On February 6, 2018, we gathered nearly all FSCI employees at the Chicago Marriott Northwest for an employee celebration to look back at and celebrate 2017 accomplishments. Some of the celebration included welcoming our newest team members, achievements of our existing staff members, the recent FSCI acquisition by PSI, business activity, and a look ahead at 2018.
Larry Robbins, Vice President of PSI, talked about the great fit that FSCI is for PSI primarily because of the family atmosphere of both companies. We also highlighted our eight newest team members including fire protection plan reviewers, field service inspectors and administrative assistants. We celebrated the promotions of Carrie Huber, Office Manager, and Gina Giannone “Arizona” Administrative Assistant. We also presented “Milestone Awards” to six team members recognizing them for 5 to 15 years of service.
As a company, we reviewed many marketing initiatives in 2017; vendor shows in many states, numerous seminars across the world including several presentations in the Middle East and Asia, and quarterly newsletters read by about 8,000 clients and customers.
During 2017, the FSCI team reviewed and processed 5,500 plans for compliance, an average of 460 per month. Our reviews included 228,000 sprinklers, 55,000 fire alarm devices and performed 1,900 inspections. We discussed the many large, complex plan reviews, field services, and consulting projects across North America.
Finally, we looked ahead at some exciting changes coming in 2018. These upcoming changes include the creation of a seamless office environment through a cloud-based telephone system, electronic plan review process, and specialized accounting and client information software.
A special thank you to all our clients and exceptional staff for another great year!
Schools and Manual Fire Alarm Boxes
With the recent school shooting incident in Florida, much attention is now being given to how the building’s fire alarm system aided the shooter in his plan to inflict pain and death on the occupants. The shooter activated a manual fire alarm box (also known as a pull station) which caused the notification appliances within the building to activate. The expected action of the students and faculty occurred. Building evacuation began which is exactly what the shooter was hoping to accomplish.
Since the incident there has been an interest, mainly among school officials, in removing manual fire alarm boxes from schools; or, at least to delay the activation of notification appliances if a manual fire alarm box was activated. Obviously, nobody wants a repeat of the Florida incident. Having attended several recent meetings with fire code officials and fire inspectors groups, school officials are looking for guidance in what to do with manual fire alarm boxes in their facilities. Model building and life safety codes allow for the removal of manual fire alarm boxes under certain conditions. Locally adopted codes should be reviewed to see if these devices are permitted to be removed.
If manual fire alarm boxes must be retained within a building, and a box is activated, do codes and standards permit a delay in the operation of notification appliances until the reason for the activation is investigated?
NFPA 72 is referenced by all of the model building, fire, and life safety codes in the United States and many school codes including in Illinois. The purpose of NFPA 72 is to define the means of signal initiation, transmission, notification, and annunciation (72-1.2.1) for fire alarm and signaling systems.
In general, NFPA 72 (2016 edition) includes the following requirements:
72-10.11.1 requires the actuation of alarm notification appliances (horns, bells, strobes), or the EVAC system, within 10 seconds of the activation of an initiating device (smoke or heat detector, manual fire alarm box, waterflow switch, etc.).
NFPA 72 has, for many years, allowed for the delay in the activation of notification appliances upon receipt of a signal from an initiating device. The original purpose of these two available methods was to minimize nuisance fire alarm signals (typically from smoke detectors). The use of these functions was never intended to deal with an active shooter incident.
The two functions are:
1) Presignal Feature (72-188.8.131.52)
2) Positive Alarm Sequence (72-184.108.40.206)
The use of either method requires the approval of the authority having jurisdiction.
Fire safety professionals familiar with the two methods tended to avoid approving the Presignal Feature as this function normally requires human intervention to activate the general alarm signal. Presignal requires that the following conditions be met:
The initial fire alarm signals only in department offices, control rooms, fire brigade stations, or constantly attended central locations (By nature this is Private Mode signaling – Author’s note)
Where there is a connection to a remote station, the transmission of the fire alarm signal to the supervising station activates upon the initial alarm signal.
Subsequent system operation is by either of the following means: *Human action that activated the general fire alarm (By nature this is Public Mode signaling – Author’s note
*A feature that allows the control equipment to delay the general alarm by more than 1 minute after the start of the alarm processing (Author’s note: There is no maximum time)
Positive Alarm Sequence tends to be a more favorable method to permit the delay of general fire alarm signals, but is intended to be used to reduce nuisance alarm signals from automatic fire detection devices (smoke and heat detectors), not manual fire alarm boxes. Positive Alarm Sequencing allows a delay in alarm activation for as much as 180 seconds as long as the alarm signal is acknowledged within 15 seconds. This generally works well to reduce nuisance alarm signals, but would not be applicable if someone were to activate a manual fire alarm box. The entire text of the requirements for Positive Alarm Sequence is shown below.
220.127.116.11.1.1 The positive alarm sequence operation shall comply with the following:
To initiate the positive alarm sequence operation, the signal from an automatic fire detection device selected for positive alarm sequence operation shall be acknowledged at the fire alarm control unit by trained personnel within 15 seconds of annunciation.
If the signal is not acknowledged within 15 seconds, notification signals in accordance with the building evacuation or relocation plan and remote signals shall be automatically and immediately activated.
If the positive alarm sequence operation is initiated in accordance with 18.104.22.168.1.1(1), trained personnel shall have an alarm investigation phase of up to 180 seconds to evaluate the fire condition and reset the system.
If the system is not reset during the alarm investigation phase, notification signals in accordance with the building evacuation or relocation plan and remote signals shall be automatically and immediately activated.
If a second automatic fire detector selected for positive alarm sequence is actuated during the alarm investigation phase, notification signals in accordance with the building evacuation or relocation plan and remote signals shall be automatically and immediately activated.
If any other fire alarm initiating device is actuated, notification signals in accordance with the building evacuation or relocation plan and remote signals shall be automatically and immediately activated.
In-Building Mass Notification Systems (MNS), covered extensively in 72-24.5 have been addressed in NFPA 72 since the 2010 edition was published. These systems are designed, and intended, to be installed in buildings and structures for the purpose of notifying and instructing occupants in an emergency.
Typically, MNS is combined or integrated with EVAC systems. The systems can share a notification system which makes it easier to coordinate the signals from the fire alarm system and the MNS. NFPA 72 allows priority MNS messages, as determined by a risk analysis, to take precedence over fire alarm signals. As an example, the MNS automatic message which might be used to automatically announce the need to go into lock-down mode during an active shooter incident would take precedence over a fire alarm system initiating device activation signal.
MNS is permitted to operate with recorded messages or by live voice. Use of live voice does not automatically put the entire system into MNS mode. Only authorized personnel shall be permitted to control message initiation over the MNS. Remote activation of the system is permitted if stated in the emergency response plan (ERP).
Audible and visual signaling shall be provided for MNS. The MNS audible alert signal shall be different than the Temporal 3 signal used for fire alarm signal notification. Normally, the audible alert signal is stated in the ERP. Employees (full- and part-time) need to be trained on what different alarm signals are intended to indicate and how to respond to each signal. The color of strobes for MNS is not regulated. The same clear strobe used for fire alarm systems can be used for MNS so long as the trim plate on the appliance, or the lens, does not indicate the word “Fire”. Some manufacturers have dual lens appliances (Example: white for fire/amber for MNS).
The value of even having manual fire alarm boxes in schools is being evaluated by many individuals, groups and associations. Remember, that both NFPA 101 and the International Fire Code allow for the removal of these devices under certain conditions. Also, a delay in the activation of a general fire alarm activation signal is also permitted under the Presignal provisions of NFPA 72. Where Presignal may not have been the best method for dealing with nuisance smoke detector issues, it may be an acceptable strategy as a part of the bigger plan for dealing with today’s safety issues within buildings.

Thermal sensitivity for sprinklers is not a new term in NFPA 13. The difference between a Standard Response sprinkler and Quick Response sprinkler has been defined for a number of code editions. Quick Response sprinklers are required in light hazard areas by the IBC and NFPA. Some problems have occurred when remodeled areas have been submitted for review and the contractor has not clearly identified the type of adjacent, existing sprinklers. Often field inspectors will identify and address the mixing of sprinkler types. To further complicate this issue, sprinkler manufacturers have sprinklers that are listed as Quick Response which can cover up to 18’ x 18’. But, when the same sprinkler is spaced at 20’ x 20’ the listing changes to be Standard Response. The 2016 edition of NFPA 13 has addressed this issue. Section 22.214.171.124 states, “Where a sprinkler carries a listing for both standard-response protection and quick-response protection at different coverage areas, that sprinkler shall be permitted to be installed within a compartment at the spacing for both the quick-response and standard-response listings without any separation between the areas so covered.”
Summer is coming. Along with the warm weather comes the challenges of efficiently and effectively cooling large open areas. Many designers use packaged HVAC units which have large, associated costs beginning with the initial purchase and continuing with the daily energy expenses to operate the unit. Alternatively, designers are now looking at a more cost effective option utilizing fans.
These are not just any ordinary fans. High Volume Low Speed (HVLS) fans have become more popular in recent years. While originally designed for agricultural purposes, their uses have evolved. They are now predominantly found in large open area buildings such as assembly and storage occupancies.
The fans are designed to distribute large volumes of air at low speeds. They first appeared in the 2010 edition of NFPA 13 as a reserved section (11.1.7) since at that time there was insufficient data available related to how these fans would affect fire suppression systems. In 2011, a series of sprinkler tests were performed which included HVLS fans. The results allowed the NFPA 13 technical committee to establish rules to be followed when a sprinklered building included HVLS fans. The rules were first found in the 2013 edition of NFPA 13. No changes appeared in the 2016 edition. The requirements are as follows: 1) A 24 foot maximum fan diameter; 2) The fan shall be centered approximately between four sprinklers; 3) A minimum vertical clearance of 3 foot from sprinkler deflector to the fan blade; and, 4) The fan shall be interlocked to shut down upon receiving a signal from the fire alarm control unit, through an emergency control function interface device, upon activation of any waterflow device. The 2019 edition of NFPA 72 will include the interface of HVLS fans with the fire alarm in its Chapter 21.

NFPA 72 – 2016 Edition – Section 1.5, Equivalency
A common requirement in the Administrative chapter of most NFPA codes and standards deals with the issue of equivalency. Section 1.5.1 of NFPA 72 states, “Nothing in this Code shall prevent the use of systems, methods, devices, or appliances of equivalent or superior quality, strength, fire resistance, effectiveness, durability, and safety over those prescribed by this code.” Section 1.5.2 states that technical documentation must be submitted to the authority having jurisdiction (AHJ) which demonstrates the equivalency of the alternative allowed in Section 1.5.1; and, Section 1.5.3 states that systems, methods, devices, or appliances that are found to be equivalent shall be approved. There are two important parts found within the text of Section 1.5. First, the individual(s) desiring to use the equivalency provision bares the responsibility to provide proof to the AHJ that what is being proposed is actually equivalent to the prescribed rules found in NFPA 72 or any other code or standard from NFPA that includes the equivalency provision. This proof might include a product approval from a nationally recognized testing lab, a performance-based design, or the fact that a more recent edition of the same NFPA code or standard has already embraced the proposed equivalent system, method, device or appliance. The second important part is the AHJ who must be open to the proposed equivalent system, method, device or appliance as they are required, by the code, to approve that which is proven to be equivalent.
