TS1020 Analogue Data Gathering Panels (DGPs) are used to expand the number of inputs and outputs (or relays) on the Challenger system. It brings brand-new features to Challenger10 systems, and is backwards compatible with Challenger V8 systems.
The Challenger system uses end-of-line (EOL) resistors on input circuits to monitor the condition of alarm input devices. In a Challenger V8 system, only one value of EOL resistor could be used. When used on a Challenger10 panel, a TS1020 DGP can be used with a variety of EOL resistor values. This flexibility can greatly reduce the cost of upgrading an existing intrusion-detection system to a Challenger10 system. Also, the TS1020 DGP can measure and display (on an LCD keypad) the resistance values of its input circuits to assist in fault finding or commissioning a site. The TS1020 has eight inputs and can be expanded via additional Eight-Input Expansion Modules, models TS0021 or TS1021. Some EOL resistance values are not supported by TS0021. Please see the Eight-Input Expansion Module datasheet for further information.
