Simplex 4090-9002, Addressable Relay Module – IDNet Fire Alarm Control

Description

The Simplex 4090-9002 Addressable Relay Module provides fire alarm control panels with the ability to remotely control one Form “C” contact using IDNet addressable communication, which transmits both power and data over a single line. This compact, enclosed relay module supports control functions such as elevator recall, HVAC shutdown, fan pressurization, or damper operation, making it ideal for critical life-safety and building automation applications.

Compatible with a wide range of Simplex fire alarm control panels including 4007ES, 4008, 4010, 4010ES, 4100ES, and 4100U, the 4090-9002 enables status tracking and relay activation through a single addressable point. The module includes a low-power latching relay and an onboard LED that indicates communication activity. Optional covers are available for visibility of the LED after installation.

With its dust-resistant enclosure and reliable latching mechanism, the 4090-9002 is designed for commercial and industrial environments where reliable fire safety response and building integration are essential.
