On a Blackcomb 5.1 controller, a connection failure alarm may appear if there is an issue connecting with an attached accessory. This alarm could be caused by a bad connection with a sensor, any module, or a lamp key.

Evidence of Issue

“CONNECTION FAILURE” is displayed. Constant alarm sounding.

Causes of alarm:

• An expansion module, sensor or lamp key is not securely connected to the controller.
• The lamp key port or IEP are wet, very dirty, corroded, or damaged.

Actions:

1.            Unplug the controller from the outlet.

2.           Ensure all module, sensor and lamp key connections are secure.

3.            After 1 minute, plug the controller back into the outlet.

If the controller is still displaying “CONNECTION FAILURE”:

1.            Unplug the controller from the outlet.

2.            Unplug any modules from the controller.

3.            One at a time, plug in a module and start up the controller.

4.            If one module causes the alarm, replace that module.

5.           If the alarm is displayed without any modules or sensor connected, submit a ticket for customer support. New Ticket
