Expander/Expansion Module Failure & Data Fail

Expander/Expansion Module Failure & Data Fail

What is an Expander Module?

An expansion module is an auxiliary board that attaches to the security system’s main board. An expansion module increases the security system’s number of input/relays – which allows for more devices to be installed than a standard alarm system.

What is a Data Gathering Panel?

A Data Gathering Panel (DGP) is an auxiliary board that attaches to thealarm system’s main board. A DPG provides for additional inputs/relays much like an expansion board, but it also has the ability to attach and manage numerous expansion modules.

Expansion Module Failure:

The expander module failure signal indicates that an expansion module/s is not correctly communicating to the main alarm panel. A technical inspection generally is required to identify & rectify the cause of the fault. Until returned to normal service, it can be expected that all inputs (sensors)/ relays (controllers) attached to this expander module will no longer be able to operate as designed or communicate with the main panel. Multiple devices are generally rendered inoperative. Data Gathering Panel Failure:

The DGP failure signal indicates that a DPG is not correctly communicating to the main alarm panel. A technical inspection generally is required to identify & rectify the cause of the fault. Until returned to normal service, it can be expected that all inputs (sensors)/ relays (controllers) attached to this DPG in addition to all attached expander modules will no longer be able to operate as designed or communicate with the main panel. Multiple devices & multiple expansion modules are generally rendered inoperative.
