4.4 Safety and Code Considerations
Safety procedures and adherence to local building codes are the responsibility of the system installer. Versus
products have been designed to be safe and reliable under the conditions in which they are intended to be used.
The following sections detail those aspects of the system that might affect safety.
4.5 Equipment Handling
The components used in a typical installation contain internal circuits that are sensitive to static electricity.
Static electricity transported by the human body may be strong enough to damage internal circuitry during
installation. These components do not normally have exposed connector pins, but if handling with exposed
connectors or pins is required, the installer should use an anti-static wristband connected to an electrical ground.
This is especially important when temporarily disconnecting and reconnecting cables. The badges are the only
system components that people can come in direct contact with. Therefore, cleaning the badges after each use
is recommended. A badge should be thoroughly cleaned after each use, and wiped down with a disinfectant.
The disinfectant should be alcohol-based, not water based.
4.6 Power Requirements
The components obtain low-voltage operating power from a local wall mounted “plug-in” transformer.
Transformers provided with the systems are Underwriter Laboratory (UL) approved. No components use 120-
volt AC line power directly, except the computer systems.
Notice: The hardware may be damaged if connections are made with the system power applied. Do not
attempt to connect or disconnect sensors, collectors, concentrators, intercom modules or any other system
components with power applied! Although damage will not occur in most cases, this practice is not
recommended and may void equipment warranties.
As with any electrical equipment, safety is a prime concern. The system poses no safety hazard, since it uses
only low-voltage DC power. However, installers must take adequate precautions to ensure that the low-voltage
wire runs do not come in contact with high-voltage electrical wires.
No powering device other than the plug-in units provided should be connected to the system without prior
authorization from the manufacturer.
WARNING
Make every effort to avoid touching bare contacts or connector pins when
handling system components in order to prevent the accidental transfer of static
to internal devices. Leave protective covers attached during installation.
WARNING
Use of powering schemes not approved by the manufacturer will void
equipment warranty.
