for Safety and Security
SABIC, the Saudi Basic Industries Corporation, recently opened the 43,000 square meter (463,000
square foot) SABIC Academy next to the company’s 17-story corporate headquarters in Riyadh,

and be trouble free.” SABIC hired AV integrator SmarTech AV to use existing outdoor security fiber optic cable to send
emergency announcements and other informational signals from two microphones over the 400

SmarTech chose the Extron FOX AV fiber optic transmitter-receiver extender set. Although SABIC
currently wants to route only audio signals between the two buildings, the FOX AV extender is made
to send video, audio, and RS-232 signals over fiber optic cable. According to SmarTech Projects
Manager Yousef Abdul Hadi, Extron equipment was chosen because of its reliability. “We knew the
FOX AV extender would perform well and be trouble free,” Hadi says.
Safety
The audio link between the two SABIC buildings includes the company’s evacuation system and
thus involves the safety of SABIC employees and visitors. In the event that an evacuation or safety
