Edwards EST 3-SSDC2 Loop Controller (New)

The Signature Driver Controller modules provide an intelligent interface between the CPU module and Signature Series devices. Each module contains its microprocessor used to coordinate the process. And interpret information received from and sent to Signature devices. Power and communications a re received directly from the control panel rail assembly. The Single Signature Driver Controller module supports one Signature Data circuit. While the 3-SDDC2 Signature Dual Driver Controller module supports two Signature circuits. Both modules occupy one rail space in the fire alarm control cabinet. And provide removable field wiring terminals to aid installation.
Innovative design gives 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 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.
