Wiring Connections

3-2 Guard-It

Owner's Manual

3.3 Phone Line Connection

Plug one end of the supplied telephone extension cord into the telephone line

jack located to the left of the connector block (

not the programming jack located

on the front panel). Plug the other end of this same cable into a telephone line

(RJ11) jack.

I Caution:

The phone line must be such that a standard telephone set can work on it.

Certain in-house PABX phone systems have “digital” line connections which

can damage the product!

Ideally this phone line should be for the exclusive use of the Guard-It

autodialer. However, the product will generally function if there is an extension

phone on the same line, as long as that extension phone is not in use when it is

time for the Guard-It

to place or receive a phone call.

3.4 Input Signal Connections

The four signal inputs on the Product can be used with several different types of

input signals, in any combination.

3.5 Connecting Unpowered ("DRY")

Contact Inputs

Connect unpowered contact inputs as shown in the diagram. Each input has

two input connection points. The points marked “C” are internally connected

together and to common ground.

M Warning:

Before making any such connections, verify that there is no electrical power

present on the signal wires, otherwise serious damage to the product could

result.

3.6 Connecting Analog or Digital Logic

Signal Inputs

Refer to Appendix A regarding analog signal inputs and Appendix B regarding

digital logic signal inputs.
