⚠️ Status: Obsolete
The EST3 is a legacy addressable suppression panel. Replacement main boards are no longer manufactured. A full system upgrade is highly recommended.
Common EST3 Trouble Codes
- MAP FAULT: The panel has detected a change in the physical wiring sequence or resistance between addressable SIGA devices on the data loop.
- AUX PORT ONE: The control system has lost communication with the FireWorks graphic workstation or external monitoring equipment due to a disconnected RS232 cable.
- GROUND FAULT: A field wire on an initiating loop or notification appliance circuit has made unauthorized contact with a grounded metal surface or conduit.
- OPEN CIRCUIT: A complete break in the physical wiring has been detected, which prevents the main loop controller from communicating with downstream modules.
