NX-2192E PINPOINT SYSTEM
2
1. GENERAL
DESCRIPTION
The NX-2192E is a microprocessor-controlled point ID bus interface module for the NX-8E control panel. The PinPoint System provides
two-wire bidirectional communications with up to 255 individually addressed devices. The total number of devices in a system is limited by
the I/O capability of the panel. The NX-8E can support a maximum of 192 zones mapped to 192 input device addresses and an additional
48 addresses for output devices. Warranty information is provided in the Interlogix product catalog.
2. INSTALLATION
The NX-2192E is installed in the NX-8E control panel enclosure. Three loop outputs are provided for interface with the point ID devices. A
single loop output can support the full 255 point ID devices as long as the wire run limits are not exceeded. The total number of devices
can be distributed across the three loop outputs to meet wire run limit requirements.
3.
DEVICE ADDRESS CONFIGURATION
Each device on the PinPoint System must be configured for a unique address with the range of 0 through 254. Address 255 is reserved.
Setting the address switches at the time that each device is installed will determine the address selection. Please refer to the worksheet
in Appendix1 on page 40.
