MR-2320 Series Releasing Control Unit


General Application From the smallest business to the largest facility or campus, small conventional panels feature large capacity power supplies and easy front panel programming while large intelligent systems lead the market in sophisticated features including distributed emergency audio and are remarkably easy to configure and program. In addition to systems, Secutron™ also offers the most complete line of advanced detection industry with the advanced system features required by emerging fire codes and new protection design practices. Large intelligent networked systems support fully redundant network modularity, graphic display annunciation/monitoring, building management system integration, programmable smoke control and multi-channel emergency communications across buildings, campuses or communities. Secutron™ systems are also supported with the largest selection of detectors, signaling devices and accessory devices, including intelligent power supplies.
