Security  The Department of Facilities is responsible for all building security systems, keys, locks, access control, employee badges, and Closed Circuit TV (CCTV) monitoring systems. The building alarm system is monitored by an offsite monitoring company that monitors the building 24/7. When an alarm occurs they follow established existing protocols and use the Department of Facilities emergency call list when notifying personnel. Any building staff persons whom the Principal allows access to the building must be given the building alarm code to deactivate the alarm system before entering. Security guards also patrol buildings on weekends and holidays.
