New Hampshire School Steps Up Its Emergency Notification Game Plan

The expansion of the school’s fire alarm system enables officials to improve communications during crises.

It can be a challenge for school personnel to make emergency announcements that reach everyone, especially if the campus has several buildings that cover a wide swath of acreage. Such was the case at the Derryfield School in Manchester, N.H. When administrators realized their campus did not have a dependable method for communicating emergency events across the entire campus, they quickly implemented a number of technological changes.

“Some of the challenges we faced were interconnecting our buildings – having something happen in one and not being able to communicate with the others,” says Gary Harper, Derryfield’s director of facility operations. “There are times we need to communicate situations quickly to all students, faculty and staff. Now that we’re connected, these messages go to all four of our buildings at the same time.”

Having depended on fire alarm systems from Notifier, installed in all campus buildings more than 11 years ago, the campus looked to capitalize on that technology.

Working with local life safety integrator, BK Systems Inc., the school was able to re-use its existing peripheral devices, needing only to upgrade its fire alarm control panels to Notifier NFS2-640 panels. Digital Voice Command (DVC) from Notifier was integrated with each panel to provide the emergency communication capabilities the school campus needed. The system is setup to send out prerecorded messages pertaining to any type of emergency. Microphones at each control panel also enable authorized personnel to broadcast live voice alerts.

“There were many programming features we were able to potentially employ, giving us the flexibility to program specific messages for various situations,” Harper says. “Now there’s a voice telling them the information they need to know instead of a blaring alarm with no instructions.”

Cross-Campus Connections Improved

Campus at a Glance

Since its start in 1964, the Derryfield School in Manchester, N.H., has offered an outstanding co-educational college preparatory education to students in grades 6-12. The school has a rigorous academic program, small classes and rich opportunities in visual and performing arts, athletics and extracurricular activities.

The four-building school is surrounded by 84 wooded acres, and has a 400-seat auditorium, two music/drama rehearsal rooms, two art studios, two art gallery spaces and a sculpture garden. It’s also equipped with a technology center, a library and three fully equipped science labs.

Tying together all fire alarm control panels onto one network would allow for easy access to information and control of any system from any panel. Emergency voice messages would also travel over this network to all buildings.

“The school wanted total control during any emergency that could happen on campus, whether it was a tornado, active shooter or other kind of serious threat to the students,” says Karlton Klardie, president of BK Systems Inc. “We set out to ensure communication between buildings and provide total control of the campus for emergency preparedness.”

To support the campus’ fire alarm network, BK Systems installed fiber optic cable within and between buildings. This network setup using fiber not only supports a high-speed of data communication between panels and real-time mass notification, but also provides a high degree of survivability. Therefore, if one or more components on the fire alarm network suffer damage, possibly from fire or other threats, the remaining pieces of the network continue to operate properly – sharing information and continuing to broadcast emergency voice alerts.

“The new Notifier technology has advanced substantially, and we needed the latest cutting-edge technology to integrate all the campus buildings together,” Klardie says. Now, four fire panels in the four different buildings allow administrators to take control of a situation from many buildings or locations.

To offer more immediate access to real time network information, NCA-2 network control annunciators were installed at each building’s main entrance, plus one was installed in the gymnasium lobby.

Harper says because of the school’s positive experience with Notifier products, it was just a matter of working with BK Systems Inc. to determine which products would meet the needs of the school. Ultimately, the new system allows end users to program specific buttons that tell students and staff when the event was a drill or alert them to a real emergency and provide instructions. All alerts, whether live or recorded messages, can be sent with the touch of a single button.

There were several challenges to updating the system – programming the entire network, making sure the fiber optic cables were routed correctly and properly updating the programming algorithms to accomplish the necessary tasks. Updating the campus’ fiber optic network was a major undertaking, but Harper says it turned out to be a beneficial problem that allowed interconnectivity between the panels. It also took BK Systems’ expertise to make sure the communication between all four systems was consistent in messaging.
