The IDP-RELAY is an addressable relay module for use with Honeywell Farenhyt Series fire alarm control panels (FACPs). The IDP-RELAY allows a Farenhyt FACP to switch discrete contacts by code command. The relay contains two isolated sets of Form C contacts, which operate as a DPDT switch. No supervision is provided for the notification appliance circuit. The IDP-RELAY contacts can be used for virtually any normally open or normally closed application. Each IDP-RELAY is programmed with a unique signaling line circuit (SLC) loop address. When an event occurs that controls the IDP-RELAY, the relay is triggered by the FACP.
