Warning
Hazard of Electric Shock: Remove all power from all devices before removing any covers or doors of the system. Disconnect power at the device and at the power source.
Electrostatic Discharge Required: Always discharge static electricity from your person by touching metal prior to handling any hardware. Failure to do so may result in damage to devices.
Issue
The panel displays an Address 1 has a wiring trouble condition. This is accompanied by a General Trouble alert.
Product Line
ESMI Fire Detection.
Environment
FFSULH2007.
Cause
The system is showing a wiring trouble condition at Address 1.
To view more details, press the “More Details” button on the panel.
This issue originates from the Input Module (FFSULH2007).
Resolution
The Input Monitor Module provides contact monitoring circuits for equipment that uses a dry contact signal.
Typical Connection Diagram
The diagram below shows a typical connection of the input module with the monitored equipment.
The circuit is monitored for wiring faults using an End-of-Line (EOL) resistor, which should be installed at the last point of the circuit.
Note: The EOL resistor is supplied inside the module box.
Troubleshooting Steps
- If the EOL resistor is removed or discarded, or if the wiring is broken, the module will detect a loss of resistance and generate a wiring trouble alert.
- The installer must ensure:
- The EOL resistor is properly connected at the last point of the equipment.
- Any broken wires are repaired or rejoined.
Once the wiring and resistor are correctly installed, the trouble condition will automatically clear.
