Actall's Personal Alarm Locating Systems (PALS) 9000 and upcoming PALS RFID use handheld devices known as Personal Mobile Transmitters (PMTs) that utilize both radio frequency and infrared signals to locate persons in duress situations. By pressing a red "panic" button, pulling a breakaway pullcord, and/or tilting the PMT unit more than 60 degrees to set off the mandown alarm, the PMT automatically communicates location and type of alarm in real time to Actall's Crisis Controller Alert Monitoring software.PALS also provides wireless technology utilizing 900 MHz spread spectrum supervised radio transmissions for quality signaling.
