The Signature Driver Controller module provides an intelligent interface between the CPU modules and Signature Series devices. Each module contains its microprocessor used to coordinate, process, and interpret information received from and sent to Signature devices. Power and communications are received directly from the control panel rail assembly. This Signature Dual Driver Controller module supports two Signature circuits. Occupy one rail space in the fire alarm control cabinet and provide removable field wiring terminals to aid installation.
Innovative design gives Signature devices truly “distributed intelligence”. Signature detectors and modules have, their onboard microprocessor communicating. With the loop controller in a fully digital communication format. This increases the accuracy of the information coming. 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 a re 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 the information transmitted between the loop controller and devices.
