Simplex 4100-3209 Relay Module, 8 Point, 3A
The Simplex 4100-3209 is an eight-relay expansion/interface module for the Simplex 4100 series fire alarm control panel, used to provide auxiliary switched outputs for controlling external equipment such as door holders, HVAC shutdown, or elevator recall interfaces.
Key Features:
• Eight Relay Outputs: Provides eight individually controlled relay outputs, each rated 3 A at 30 VDC or 120 VAC.
• Fused Contact Protection: Each relay's contact set is protected by a separate 5 A fuse.
• Low Standby Draw: Draws approximately 16 mA in normal supervisory condition and up to 200 mA with all relays activated, for battery backup calculation purposes.
• Panel Integration: Mounts within the 4100/4120 series or 4010ES expansion architecture for seamless integration with the fire alarm control panel's programmable outputs.
