DIRECT WIRE INPUTS PRODUCT DESCRIPTION:
The EOL/RPI capability allows the System 3505 to monitor up to 2048 direct-wire inputs. The interface cards for the direct-wires are available in groups of 32 inputs per card. Up to 16 cards can be daisy chained to one controller card. The EOL/RPI interfaces are available in 19" rack mount strips or plug-in cards. When large numbers of direct-wire inputs are connected, it is recommended that you use the card cage for the EOL/RPI cards. The card cage will accommodate 16 cards or 512 zones of any mix or match combination of EOL/RPI cards. Power to operate the EOL/RPI cards is provided by the System 3505. The direct-wire option should be ordered to allow installation of the first 16 EOL/RPI cards.
