Safety Considerations
Improper installation, adjustment, alteration, service, maintenance, or
use can cause explosion, fire, electrical shock, or other conditions which
may cause death, personal injury or property damage. Consult a
qualified installer, service agency or your distributor or branch for
information or assistance. The qualified installer or agency must use
factory--authorized kits or accessories when modifying this product.
Refer to the individual instructions packaged with the kits or accessories
when installing.
Follow all safety codes. Wear safety glasses, protective clothing, and
work gloves. Have a fire extinguisher available. Read these instructions
thoroughly and follow all warnings and cautions included in literature
and attached to the unit. Consult local building codes and the current
edition of the National Electrical Code (NEC) NFPA 70.
In Canada, refer to the current editions of the Canadian Electrical Code
CSA C22.1.
Recognize safety information. When you see this symbol
and in instructions or manuals, be alert to the potential for personal
injury. Understand the signal words DANGER, WARNING, and
CAUTION. These words are used with the safety-alert symbol.
DANGER identifies the most serious hazards, which will result in severe
personal injury or death. WARNING signifies hazards, which could
result in personal injury or death. CAUTION is used to identify unsafe
practices, which may result in minor personal injury or product and
property damage. NOTE is used to highlight suggestions which will
result in enhanced installation, reliability, or operation.
Installation Considerations
The Remote Access Module, part number SYSTXNNRCT01, is
powered with a field-supplied 24VAC transformer. A 120VAC supply
must be near the mounting location when using the accessory plug-in
24VAC transformer. Provisions must be made to secure the accessory
plug-in transformer to the outlet. The D-wire (24VAC) from the
communicating system must NOT be used to power the Remote Access
Module, and should not be connected to the module.
This instruction covers the physical installation and start up. Use this
instruction to guide the actual installation process after the
communicating system(s) have been installed. One Remote Access
Module is capable of handling two communicating systems.
