Polon-Alfa EKS-4001W input/output devices are designed to react to a signal given off by the control panel to activate the alarm and fire-protection devices, such as signaling devices, fire dampers, and fire-protection doors, etc., using relay contacts. They enable control over the efficiency and proper activation of the controlled unit. The EKS-4001W devices have an additional input designated to supervise devices or installations not related to control operations. The EKS-4001W input/output devices operate only in lines/loops of the POLON 4000 system addressable fire alarm control panels.
