The Signature Driver Controller modules provide an intelligent interface between the 3-CPU3 and Signature Series devices. Each module contains its own microprocessor, which coordinates, processes, and interprets information received from and sent to Signature devices. Power and communications are obtained directly from the control panel rail assembly.
The Signature Dual Driver Controller module supports two Signature circuits. It occupies one rail space in the fire alarm control cabinet and provides removable field wiring terminals to aid installation.

Signature detectors and modules have an onboard microprocessor that communicates with the loop controller in a wholly digital format. This increases the accuracy of the information coming to. And from the loop controller by reducing the effects of capacitance and noise.
With decentralized intelligence, much of the decision-making moves from the loop controller to the devices. Advanced fire detection algorithms processed within the Signature devices effectively end unwanted alarms. Environmental compensation and multiple sensing element decision-making operations are resident in the devices.
Intelligent devices allow the Signature Controllers to execute communication and system functions with greater speed and low baud rates. Increasing the accuracy of information transmitted between the loop controller and devices.
