A transparent solution
Glass door system provides aesthetic benefit, along withprotection
Technical Glass Products
The design of the Mary & Leigh Block Museum of Art on the campus of Northwestern University, Evanston, Ill., includes both an outer and inner lobby separated by a wall andto help protect the museum's treasures from fire and inclement weather. At the time of the museum's design and , few options for fire-safe doors were available.
“Visitors would enter the outer lobby and be greeted by four imposing steel doors,” says David Robertson, the museum's director. “They would be confused about where to go next.”
The doors provided a vital function in terms of fire protection, but they blocked the view of the information desk. The museum needed glass doors that could offer clear visibility, in addition to the same fire protection as the steel doors.
The museum chose to install a fire door system from Technical Glass Products, composed of Fireframes Heat Barrier Series steel framing and Pilkington Pyrostop glass. The frames and glass have fire ratings up to 90 minutes in doors and allow doors to contain a full lite of glass.
Because this system is tested to the same standards as a wall, it not only blocks flames and smoke, but also acts as a barrier to heat transfer. A fire could be raging on one side of the glass, and the opposite surface would be cool enough to touch. Because it meets these criteria, Pilkington Pyrostop can be used in openings that stretch fromto ceiling and wall to wall.
The museum lobby now features two, one-hour-rated glass doors with a large expanse of Pyrostop glass between.
“There has been marked improvement,” says Robertson. “Now when we host events in the museum, people come into the lobby and know immediately where to go.”

The Johnson Controls Digital Vision Network (DVN) combines the benefits of digital video recording with sophisticated software that improves the way images can be monitored, analyzed and archived. DVN can be programmed to recognize and record specific events or anomalies, detect motion and behaviors, and respond by alerting officials. Its image analysis software can be activated to search recorded video footage for user-defined objects. DVN software suites allow remote management of complex digital video architectures.

Notification device design
The Equivalent Facilitation web-based calculator provides architects and engineers with easy access to a tool that assists in the design of audible/visible notification device circuits. By visiting the website, visitors are able to perform notification circuit design calculations by entering ceiling strobe candela values and inputting the length of the longest wall and the ceiling height of the room.

School pilot program tests biometric access control
Recognition Systems/IR Security & Safety
Robert C. Byrd High School, Clarksburg, W. Va., protects its mechanical room, the heart of the school's physical plant, with a biometric access-control system that uses a person's hand as a credential. Custodians and other school personnel must swipe their identification badge and scan their hand to enter the room.
In a proactive move to protect the school and its students, the Board of Education worked with ANSER, a non-profit public-service research institute, on a pilot installation that would serve as a model for many of the other 27 schools in the district. The mechanical room was chosen because it was the most vulnerable to someone trying to cause damage. Only a limited number of people need access to the area, so it was a good place to start, says Marcel Malfregeot, director of emergency services for the district.
The IR Recognition Systems HandReader uses the size and shape of the hand and fingers as a credential. Length, width, thickness and surface area of the fingers and hand are measured and analyzed, and the unique features are stored in a template, which is used for subsequent verification.
The scanning process takes about 100 measurements of a person's hand in only a second. After comparing the readings with the data on the person whose identification badge is being used, it either allows or denies admittance. The HandReader is linked to a small computer in the mechanical room that keeps track of those admitted, as well as those who attempt to enter when access is denied. This “audit trail” could provide valuable information if a problem were to occur.

Public view monitor
GE Infrastructure, Security
The Public View Monitor allows public venues to announce the use of video surveillance by displaying live video when the unit's PIR sensor detects activity in the camera's field of view. The monitor displays detailed video even in challenging environments. The system displays multimedia messages until a person walks by and activates the sensor, switching the monitor to a live image.

Fire protection upgrade
Educational community connects life-safety systems through fiber-optic network
Siemens Building Technologies
Cranbrook Educational Community, Bloomfield Hills, Mich., comprises a 1,600-student independent college-prep school and an Academy of Art serving 150 graduate students. The campus has 70 buildings and a total of 1.5 million square feet of floor space.
The first networked, addressable fire-detection system installed in the Cranbrook residence halls in the mid-80s was based on Siemens' MXL, a microprocessor-controlled, analog fire-protection system. New fire-alarm systems were pre-designed for 33 major buildings that were designated for updated protection. The control panels would be Siemens' MXLV and would include voice annunciation and global paging capabilities.
The MXLV panels were installed as part of a multiplexed network, which provided a reliable signal back to the public-safety building for all building alarms and troubles. The next step was to begin updating detection and notification equipment in the buildings identified in the design process.
The residence halls are the highest priority for life safety. In addition to smoke detectors, pull stations, speakers and ADA strobes, video-camera surveillance is being established and networked back to the public-safety building.
As Phase 3 is completed, the Cranbrook community has its fiber-optic network in place with a panel in every building. Cranbrook Brookside School and Kingswood are complete with newly updated life-safety equipment. A similar project for the boys' residence halls will commence this year.
