There are two common conditions that can cause a system to malfunction:
- 1- Switching Modules that are not properly addressed.
- 2- Buses are improperly connected (system bus, high-level bus, low-level bus).
Either of these conditions can cause the system to be “confused” since the Control Panel cannot then communicate with all switching modules. All of the module addresses should have been set and all the bus networks connected by the person(s) who originally installed your system. If this was not properly done or if any module addresses have been changed, or new modules added to the system since the original installation, someone will have to verify all the address settings and check all the bus connections in your system before further troubleshooting can continue.
