Section 6 Wiring
This section explains how to wire the LCD-160 for communication, power, and security.
6.1 Overview
Complete all mounting procedures and check all wiring before applying power. The terminal block and
pin connections are illustrated in Figure 1. Electrical connections are listed below and are detailed in the
following paragraphs:
• TB1 - Remote Data Port (RDP) interface connection.
• TB2 - Power Supply connection
• J1 - Key Switch connection
• J4 - NUP Port (Future use)
Power-limited wiring must remain separated from nonpower-limited wiring by at least
0.25 in. (6.4 mm), and must enter an enclosure through different knockouts. Install tie wraps and
adhesive squares to secure the wiring.
!
WARNING: Remove all power sources to equipment while connecting electrical components. Leave
the external, main power breaker OFF until installation of the entire system is complete.
!
WARNING: Several sources of power can be connected to the control panel. Before servicing the
control panel, disconnect all sources of input power including the battery. While energized, the control
panel and associated equipment can be damaged by removing and/or inserting cards, modules, or
interconnecting cables.
