The Simplex 4098-9682 is a 4-wire mounting base providing auxiliary alarm relay output for use with Simplex TrueAlarm photoelectric and heat detectors on conventional 4-wire initiating device circuits (IDCs). The 4098-9682 base features a single Form C relay contact and connections for a remote alarm LED indicator, enabling local auxiliary control functions such as HVAC shutdown. External 24 VDC power is required for relay operation. Part number 0677211; covered under datasheet S4098-0015.
