System Status LED

The System Status LED is a bi-color (red & green) LED. It illuminates to indicate the status of radio communications between the SC3100 Radio Communicator and the Central Station. It also is used to indicate a LOW INTERNAL BATTERY condition, and/or identify a hardware failure on the SC3100 during system initialization.

Radio Status LED

The Radio Status LED is a bi-color (red & green) LED. It illuminates to indicate transmit (red) and receive (green) Status of the SC3100 internal radio module. This indication is helpful when sending and receiving signals.

RJ31X Modular Jack

This is a standard 8 pin RJ31X compatible female modular phone jack which is used for connecting the SC3100 to the premises RJ31X telephone jack (Tip & Ring on PINS 4 & 5 and House Phone return from the alarm panel on Pins 1 & 8).

Dialer Modular Jack

This is a standard eight-pin RJ31X compatible female modular phone jack which is used for connecting the SC3100 to the alarm panel “phone line in & house phone out” (Tip & Ring to alarm panel on Pins 4 & 5 and house phone return from the alarm panel on Pins 1 & 8).

Main Interface Molex Connector

This is a specially keyed, female Molex connector. This connector is provided for interfacing the required 12VDC power from the host alarm panel auxiliary power supply. The SC3100 comes supplied with a mating male Molex connector with a flying lead wiring harness for wiring the 12VDC power. The 12 VDC power is provided by the Red (+) and the Black (-) wire leads on the Molex connector wiring harness.
