SEC-H-600 SECURITY CONTROLLER

Digital Input

The SEC-H-600 controller has three (3) digital inputs, located on a 4-position connector next to supervised input connector (see
Fig. 4 on page 12). 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 SEC-
H-600 controller.

NOTE: The WEBs-AX Security Application is pre-configured to support the following connections:
DI1 — Tamper switch (typically for enclosure door)
DI2 — Battery status bad (if contacts available)
DI3 — AC power fail (if contacts available)
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.
