Simplex 4090-9118, Dual-Point Relay IAM Module – IDNet Fire Alarm System

Description

The Simplex 4090-9118 Fire Alarm Relay Module is a dual-point addressable interface module designed for use with Simplex fire alarm systems using IDNet communication. This compact module allows one addressable location to monitor two separate input contact closures and control an output relay, efficiently providing dual functionality while conserving address space on the fire alarm control panel.

Power is drawn directly from the IDNet communication channel, eliminating the need for separate wiring. The relay and input circuits operate independently and can be enabled or disabled individually through the host panel. This makes the module ideal for applications such as motorized damper control with open/closed position feedback or other fire safety automation where space and address efficiency are priorities.

Compatible with Simplex 4007ES, 4010ES, 4100ES, and 4100U fire alarm control panels, the 4090-9118 enables smart, reliable operation and flexible configuration in modern building safety systems.
