Frequently asked questions when troubleshooting about Gallagher Hardware

What do I do if the I/O Boards are going offline randomly?

Check the following that could cause HBUS devices that are going offline intermittently:

• Wiring connections,

• HBUS terminations are at the ends of the bus - nothing terminated in the middle of the bus,

• Devices are wired in a daisy chain - no star wiring.

• System’s power consumption – do they have sufficient battery power to support what is wired into the board.

HBUS Devices are not coming online but the Controller has detected the device and has events.

If a Controller is repeatedly generating a lot of these events: Controller 1 has detected a device. This indicates a probable issue with one or more of the connected HBUS devices.

Possible causes are:

• Faulty wiring that is causing HBUS device(s) to reconnect constantly.

• Not enough power to HBUS devices - if they are being powered from the Controller, the bus length may cause a significant voltage drop. A separate power supply may be needed.

• Serial number entered for the wrong kind of device, e.g. using a T15 reader serial number for a T30 reader

Which SMB kit should I use? (New Zealand & Australia).

When a user disarms using the T30, it creates a tamper event

If continuously happening, this generally refers to an issue of how the T30 has been mounted.

The correct type of screws need to be in all four corners for the device to be mounted to reduce tampers. Refer to the T30 Keypad Reader Installation Note.
