IAM S4090-0001 Single Address Communication Device

Individual Addressable Module IAM S4090-0001

The IAM (Individual Addressable Module) S4090-0001 is a single-address interface module used in IDNet or MAPNET II addressable fire alarm systems by Simplex/Autocall.

It allows the connection of dry contacts from switches, relays, or other peripheral devices to the fire alarm system, turning them into individually addressable monitoring points on the signal line.

Key Features
