Fire Fused Output Board - 4 Fused Outputs | FFOB-4

The FFOB-4 is a fire switching relay board designed to provide safe and controlled power distribution for fire alarm, access control, and life safety systems. Featuring four individually fused outputs, the unit allows multiple devices to be switched or disconnected during a fire alarm activation while maintaining circuit protection.

Designed for integration with fire alarm systems using voltage-free contacts, the FFOB-4 is ideal for controlling magnetic locks, door release circuits, access control equipment, and other safety-critical devices that require automatic operation during emergency conditions.
