Fire Alarm Must Meet a Different Set of Rules at Detention Center

Prisons are challenging environments to protect from fire. Placement of fire alarm components within common areas often leads to system tampering and disablement. Locating a fire within a network of cells without the help of modern technology is futile. To be effective, prison fire protection systems must incorporate highly intuitive, cutting-edge technology in compliance with local regulations and applicable standards.
The Coastal Bend Detention Center near Robstown, Texas is a new $30 million federal detention facility. It is expected to house more than 1,000 prisoners arrested by federal agencies such as the U.S. Marshals, Immigration and Customs Enforcement and the U.S. Border Patrol. Facility construction and daily operations are overseen by LCS Corrections Services, one of the nation’s largest private prison operators.
Per LCS’ specifications, the detention center was built to resemble a mini, high-tech city. The complex boasts video and computer technology for fire and security systems. Its medical facilities include an emergency room, X-ray equipment, dental office and isolation cells. A track, basketball courts and soccer fields comprise the outdoor recreation areas. An educational facility and library are also located on prison grounds.
The buildings are independent of each other, yet all must have connected security and fire detection systems. Moreover, its remote location makes for longer response times from the local fire department.
When it came time to outfit the Texas prison with fire detection and security systems, the concerns were numerous, but ease-of-use was a top priority. The facility’s management did not want staff concerned over operating the system during an emergency.
Richard Henke of On Guard Systems, a Lafayette, La.-based fire alarm and security integrator, designed and installed the prison’s fire alarm system.
“We wanted something that was reliable, flexible and code-compliant,” Henke said. “The guards need to be alert at all times so a system that can be easily understood and used was essential.”
Utilizing four MS-9600LS addressable fire alarm control panels, manufactured by Fire-Lite Alarms, Northford, Conn. as the brains of the prison’s extensive system, Henke was able to satisfy code and customer requirements. Supporting up to 318 addressable devices on one SLC (signaling line circuit), the MS-9600LS’ capacity can be quickly expanded to 636 points via an optional second loop.
“Although it’s designed to perform some specialized functions, this is a pretty straightforward system that’s easy to use,” said Jay Crick, project manager with MWL Construction, the general contractor.
The panel’s compact design and simplified programming navigation make it a cost-effective solution for many medium- to large-size applications. Furthermore, the non-proprietary availability of parts makes for easy maintenance of Fire-Lite systems.
“This way, any repair crew can make the adjustments or repairs if the system encounters a problem,” Henke related. “Service calls can be expensive. The prison needed a system that anyone can service.”
Fires are a common problem within prisons, typically taking place in locked cells when inmates are present. Considering the small space and restricted means of egress, early detection and response are critical. Consequently, code requires addressable point detection within all cells.
Fire alarm devices, such as initiation and notification appliances, when vandalized, are not only expensive to repair or replace but also present a variety of life-safety hazards. With this in mind, the entire system’s detectors are protected with stainless-steel baskets. Additional anti-vandalism measures were taken when encasing the system’s wiring in conduit run underground and within the facility’s walls.
“Prisoners have a lot of time to think about how they can dismantle a camera or destroy a detector. We have to ensure the detectors are not ripped down and fashioned into weapons,” Henke explained. “We had to think as much about protecting the detectors as protecting the prisoners.”
NFPA 101, the Life Safety Code requires new jails to be constructed of limited- or non-combustible materials. Automatic fire sprinkler and detection systems are mandated to be present throughout. When dealing with potentially hostile facility types, NFPA 101 also requires a manual, automatic or combination manual/automatic fire alarm system to be installed.
More than 500 detectors and sprinkler heads were placed throughout the detention center.
“The whole facility is sprinkled, which includes sprinklers in every cell,” Crick said. “The fire alarm is tied to the sprinkler system, so if water is released, it triggers an immediate alarm.”
This project used photoelectric smoke detectors made by Fire-Lite Alarms, and duct detectors, strobes and horn-strobes manufactured by System Sensor, St. Charles, Ill.
Henke remembers this fire alarm’s specifications were very particular, requiring most above-ground components be covered in a way that deters tampering. The system’s head-end controls also were required to be split up. Therefore if a portion of the system were damaged during a riot, the other system areas would not be affected.
Riots are common events in detention facilities. To break up riots, guards utilize smoke tear gas bombs, which can wreak havoc on a typical fire alarm system. With this in mind, the systems protecting the prison’s larger gathering areas such as the cafeteria and recreation room were configured to annunciate alarms and clear away smoke in specialized patterns.
“We can’t evacuate prisoners, so we evacuate the smoke instead,” explained Henke. “If a fire breaks out, it’s essential to be able to clear the smoke and get to the source to extinguish it quickly.”
Henke programmed each system to activate notification appliance circuit (NAC) devices, sounding an alarm within one minute before powering on fans to clear the area of smoke.
In compliance with Texas jail standards, all prisoner compartments were tested using smoke bombs to ensure proper activation of smoke detection devices. The removal of smoke via ventilation systems triggered by the MS-9600LS panel was timed during tests conducted within each of the detention center’s 216 compartments. All tests were successful, passing on the first try.
“We haven’t had to use the system for any emergencies, but it’s tested routinely,” Crick said.
According to Crick, the facility received its first residents in March 2009. There are an estimated 700 inmates already housed there. When filled to capacity, the detention center is expected to generate more than 200 jobs and $1 million a year in local revenue.
The facility is said to have multiple layers of security inside its walls. Outside the 250,000-square-foot facility is a 15-foot fence topped with razor wire, surrounded by a stun fence with a concrete barrier below to prevent potential escapees from digging their way out. Suiting such a complex facility with a straightforward, user-friendly system was no easy task.
“We had our share of challenges, but I believe this system has exceeded everyone’s expectations,” Henke said.
