IAM 4090-9002 Addressable Relay Module (IDNet)

Addressable Relay Module – Relay IAM 4090-9002 (IDNet)

The Relay IAM 4090-9002 is an addressable relay module in the IDNet device series from Simplex/Autocall.

It allows the fire alarm control panel (FACP) to remotely switch a relay contact at the installation site. This enables the system to activate or deactivate peripheral devices such as fans, sounders, bells, elevators, or fire doors through the addressable fire alarm network.

Key Features

• Individually addressable: Each Relay IAM is assigned a unique address, allowing the control panel to identify and control it precisely.

• Versatile relay output: Can control low-voltage equipment or provide trigger signals to other technical systems.

• Powered from IDNet line: No external power required for the logic circuit, reducing wiring costs.

• Compact design: Fits inside a standard 1-gang electrical box or protective enclosure.

• Integrated status LED: Provides visual indication for easy maintenance and troubleshooting.

• International certifications: UL, ULC, FM approvals ensure reliability and compliance for professional fire protection systems.
