The Simplex 4090-9002 is an IDNet Relay Individual Addressable Module (IAM) designed to enable Simplex fire alarm control panels to control a remotely located Form “C” dry contact using IDNet addressable communications. This low-power, latching relay module provides both power and data over a single two-wire circuit, making it ideal for applications such as elevator capture, HVAC control, pressurization fans, dampers, and other switching functions. Relay status is communicated back to the panel, requiring only one device address.
