The CoilKeeper Supervisory Switch helps users to improve coil monitoring on preaction and deluge system solenoids on their fire suppression systems. The product observes and reports on the position of a solenoid coil found in most sprinkler systems. When a coil is removed, the device activates a set of contacts that will send a supervisory alert to the releasing control panel, letting maintainers and facility personnel know the system is currently being worked on.
