SEC-H-602 AND SEC-H-616 SECURITY CONTROLLER

Digital Input

The security controller has three (3) digital inputs, located
on a 4-position connector next to supervised input
connector (see Fig. 4 on page 11). Under the connector,
terminals are labeled GND, DI1, DI2, DI3. This means
when wiring, as many as three conductors can be landed
to the common GND terminal.

Each digital input can monitor dry contacts, either
normally-open (N.O.) or normally-closed (N.C.). All three
inputs are unsupervised—no end-of-line resistors are
required. Figure 12 below shows example wiring to all
three digital inputs of the security controller.

Depending on the installation, not all DIs may
require connection. In almost all cases, input
DI1 is wired to the tamper switch of the
WEBs-AX Security Enclosure housing the
Security Controller.
