Four Fireray beam smoke detectors from FFE have been installed by SimplexGrinnell at the new Los Angeles Federal Courthouse to ensure optimum fire detection in its large atrium.
Managing Director Mark Osborne explained that due to the height of the atrium, convention smoke detectors were not suitable, and the Fireray 5000 auto-aligning, reflective smoke detectors were ideal as they provide extensive coverage and minimal cost.
A beam of invisible infrared light is transmitted across the building space by the Fireray 5000. The light is then detected by a receiver and measured, allowing it to recognise smoke interference anywhere along the beam path, triggering the alarm signal when the pre-determined threshold is reached.
The ‘low level controller’ feature was a deciding factor in the specification for this application as it means maintenance and testing can be carried out via the control room. Physically accessing the units is expensive and impractical according to SimplexGrinnell’s Construction Manage Sharon Brown.
Another crucial factor was the Fireray 5000’s ‘auto-alignment’ feature, due to the fact that the beams remain aligned during building movement, without causing nuisance alarms or requiring a technician. This was an important factor for a new-build project.
Situated in downtown Los Angeles, the new ten storey, 633,000-square-foot courthouse contains 24 courtrooms and 32 judges’ chambers and sustainable features such as a serrated facade which maximises views yet also reduces solar heat gain by nearly 50 percent.
For installers and engineers looking for smoke detection in large open areas, Fireray is the first choice. With its modern design aesthetic and minimal footprint, the Fireray is popular with architects and facilities managers and over half a million optical beam detectors have been installed worldwide.
