The Division of Public Safety, in conjunction with the Division of Facilities and Real Estate Services (FRES), developed and installed the Penn Siren Outdoor System (PennSOS). The 23 outdoor-speaker system operates as part of UPennAlert Emergency Notification System, transmitting voice intelligible emergency messages and alert tones to the outdoor campus environment. PennSOS is not designed to penetrate buildings, but will be audible above normal street noise.
PennSOS is one of several delivery methods for disseminating a UPennAlert Emergency Notification. Currently, the UPennAlert System serves fifty-six thousand (56,000) Penn affiliates by delivering emergency notifications via electronic devices. PennSOS provides a second layer of protection for the Penn Community, offering the advantage of communicating with all individuals located outdoors, throughout Penn’s campus. These individuals might not otherwise receive emergency notification if they are not registered with the UPennAlert System, or are not a Penn affiliate. In the event of a major emergency, both systems could be used to alert people in the area of an immediate, dangerous situation.
Benefits of PennSOS:
To promote system reliability, monthly tests, using Westminster Chimes, will be conducted on the first Friday of each month at 11:00 a.m. In compliance with the Clery Act, PennSOS is tested annually, in conjunction with the annual UPennAlert drill, using the actual siren. Notifications are made to the community in advance of this test. You can hear all possible sounds below.
Testing: Systems tests of the PennSOS will be conducted using Westminster Chimes.
Emergency: In an emergency you will hear a fifteen (15) second siren followed by a voice intelligible message instructing you on what to do. This will repeat three (3) times
All Clear: When it is deemed safe to resume your normal activity, the system will emit a series of beeps followed by a voice intelligible message indicating it is “All Clear”.
