Troubleshooting SHUBS

No LED’s are on:

• Check that jumper JP3 is in position.

• Put your finger close to (but not touching) the solid state fuse (see figure 1). If it is hot, then one of the sensors or buses is shorted to ground.

• Check the two-wire, power and ground, for correct and secure connection.

• Check the voltage at “Power IN” at connector J7 on the Domain 350. The voltage should be between 10VDC and 13.5VDC.

• Check the remote power supply for secure wire termination and output voltage 12V LED is on and 5V LED is off.

• The board is bad and needs to be replaced.

All LED’s are dim:

• Inspect sensors and the RS-485 network for shorted wires.

Link and Activity LED’s are off:

• If the Link LED is off, check the 10/100 Ethernet switch or 10BaseT hub for power and cable connectivity.

• If the activity LEDs are off and the Domain 3000 is up and running, then reset the Domain 350 by putting a paperclip into the reset hole on the front of the unit.

RS485 LED is off:

• If the Domain 350 is the first device on the RS485 network, the LED will be off after connecting with controller.

• As RS485 devices become operational on the RS485 bus, the LED will flash.

• Check wiring and connections to the RS485 bus.

System LED does not flash 1 flash per 10 seconds:

• The Domain 3000 controller is not up and running.

• Shub is has not received an IP address from Domain controller. Check the network.

Port A – P sensor LED’s all off:

• Replace jumper JP1.

• All 16 sensors are normally closed (e.g., Acuity 47 or door contacts) and not active.

Domain 350 intermittently powers down:

• A sensor shorts power to ground upon activation, often times a contact sensor, locate and remove short.
