3.6 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.
3.6.1 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. Do not immerse or autoclave badges.
Warning:
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.
3.6.2 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 120V AC line power directly, except the computer systems.
Warning:
Do not attempt to connect or disconnect concentrators, collectors, sensors, or any
other system components with power applied. The hardware may be damaged.
Although damage will not occur in most cases, this practice is not recommended
and may void equipment warranties. Use of powering schemes not approved by the
manufacturer will 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 wires are not exposed to high-voltage electrical wires, and that wires
run through ceilings and walls do not encounter dangerous electrical potentials and carry them to
points where they might be exposed to human contact.
No powering device other than the plug-in units provided should be connected to the system
without prior authorization from the manufacturer.
