The security staff has an office, which includes a set of three cells, although only the middle one has been seen in use (usually when one or more of the main characters get arrested and are put in it). The security office is also the location of the mall's PA system. Jonesy was once hired to man the system, but was fired when he used it for personal purposes. Prior to being fired, Ron trapped him in a corner, as the rent-a-cop didn't want Jonesy wandering all over his office and messing with his stuff. Jonesy's firing was largely due to Ron's intense dislike of both Jonesy and his behavior. It didn't help that Jonesy sent Ron off on bogus "emergencies" while he was in charge of the system; in fact, these emergencies were probably part of the reason for his firing, as Jonesy was in all likelihood lying about most of them.
Despite Ron being the only known member, he is often seen using his walkie-talkie to transmit information. It is unknown if Ron has other security officers manning separate parts of the mall, or if he just likes to send messages through his walkie-talkie even when nobody is listening. It is also entirely possible that, given the size of the Galleria Mall (which has almost a thousand stores), Ron is required to report all disturbances to the police.
