Silent Knight, Maple Grove, Minn., introduced its expanded IntelliKnight Series at last month’s ISC West Conference & Expo. The addressable fire alarm control panels now support synchronization of system sensory A/V appliances and a USB programming port. The 5820XL boasts an improved power supply capacity of six amps and a new deaf-front option that allows for reset, silence and acknowledge functions without requiring a user code or operator’s key.
