The SILENT-KNIGHT-SD500-ARM is an addressable relay module that lets IntelliKnight fire alarm control panels switch discrete contacts by code command.
Outfitted with two sets of Form "C" contacts, the SD500-ARM gives you control of elevator recall, door closing, fan operation, auxiliary notification, and many other normally open and normally closed applications. Flexible relay programming allows for zone condition mapping.
