Product Description
The VID Fire-Kill Model WAC and AFA valves are wafer style wet alarm check valves with a unique anti-false alarm unit integrated, designed for detection of small changes in water flow commonly found in low pressure watermist systems, making it possible to easily and reliably detect system actuations and changes to pressure. The Anti False Alarm Unit ensures that false alarms created from pressure burst will not be detected. The Model WAC and AFA valves use 12-24VDC and send a relay (NO or NC) signal in case of water flow. The valves have a flow test arrangement built into the valves and are very compact compared to more conventional solutions.
