- Page 2 OPERATION The Engine Shutdown Restart unit is a low voltage microcontroller unit designed to integrate with the Sea-Fire Fire Suppression System to shut down the engine(s), blower(s), generator(s), damper(s) and other machinery in the protected space should fire or extreme overheating cause the Sea-Fire automatic Fire Suppression System to discharge.
- Page 3 agent, in its proper concentration, will remain in the enclosed compartment and not be ingested or reduced by the running machinery. Immediately upon agent discharge, the ESRS PS1 closed loop circuit opens, activating the alarm and de-energizing all the relays. De-energizing the relays will change the state of the internal contacts and shut down all the machinery connected to the ESRS unit.
- Page 4 Mounting the ESRS Unit Use the ESRS unit 4 mounting screw holes (screw not included) to mount the unit. Connect the Display Panel to the ESRS unit via the RJ45 socket using the CAT-5 cable. Longer CAT-5 cables (10’, 20’, 50’, 100’ and 150’) are available to increase the distance between the ESRS and the Display Panel.
