Eight-input expansion modules add eight inputs to Tecom Data Gathering Panels (DGPs). This provides an inexpensive way to increase the capacity for detection sensors and other inputs on the system.
Up to three eight-input expander modules can be connected to a DGP to provide 32 inputs at the DGP address (refer to Specifications for DGP compatibility).
Using more than one eight-input expansion module on a Challenger V8 system to expand a DGP beyond 16 inputs (via TS0820 DGP or TS1020 DGP) will reduce the total number of DGPs available on the Challenger V8 system. This reduction in capacity will not occur when using a Challenger10 panel.
Challenger10 panels make upgrading from other systems easy via a wide range of end-of-line (EOL) resistor values for input devices connected via the main panel or via a TS1020 Analogue DGP. The TS1020 Analogue DGP will support both versions of the EightInput Expansion module, however as the TS0021 has limited support for variable EOL values Interlogix recommends using a TS1021 eight-input expansion module on a TS1020 Analogue DGP.
