Chapter 1: General Overview
CAUTION
In order for "alarm dialing equipment" to be able to seize the phone line to report an
alarm or other event when other customer equipment (telephone, answering system,
computer modem, etc.) connected to the same line is in use, "alarm dialing
equipment" must be connected to a properly installed RJ31X jack. The RJ31X jack must be
connected in series with, and ahead of, all other equipment attached to the same phone line. If
you have any questions concerning these instructions, you should consult your telephone
company or a qualified installer about installing the necessary jack and alarm dialing equipment
for you.

DANGER
Turn off the main electrical disconnect switch prior to servicing any of the system
modules. Failure to do so might lead to serious injury or death.
Always use extreme caution when measuring voltage or performing procedures that require a
module to be powered on.
IMPORTANT: Ensure all your settings are properly configured. Improper configuration of your settings
may generate false alerts or fail to generate an alert.
Electrostatic discharge prevention
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs
when electronic components are improperly handled and can result in complete or intermittent failures.
