描述：Beghelli Maxima Exit or Sortie - Self-Luminous Exit or SortiePRODUCT OVERVIEWThe MAXIMA series of self-luminous exits are designed for?easy installation. The use of internally sealed tritium gas as?the illumination source reduces general maintenance issues?and operational costs. The MAXIMA series does not require?electrical power, wiring or batteries. The MAXIMA series is?available in single or double face versions. Housings are available?constructed from durable corrosion resistant thermoplastic or?industrial grade aluminum, please specify when ordering. The?MAXIMA series is offered in 10, 15 or 20 year versions. Signs?can be specified as ceiling or wall mount.EXTERNAL SPECIFICATIONSThe MAXIMA series housing is available constructed from?durable, corrosion resistant ABS thermoplastic or optional?industrial grade aluminum. The MAXIMA faceplate is supplied?standard with a red stencil and white frame finish (other colours?are optional). Wall or ceiling mount configurations are available.?Single or double face versions must be specified. Removable?field adjustable chevrons are standard on each fixture.INTERNAL SPECIFICATIONSSELF-LUMINOUS: standard self-luminous versions are?internally illuminated by maintenance free sealed tritium filled?tubes. Tritium source illumination provides constant emergency?illumination as specified for either ten [10], fifteen [15] or twenty?[20] years.PRACTICAL DESIGNThe MAXIMA series has been designed to perform in just?about any environment. Requiring no external power source,?installation is effortless and efficient. The practical design of the?MAXIMA series allows installation and maintenance to be at a?minimum. Since an external power source is not required, the?installation of the MAXIMA series is not restricted by location or?the lack of an easily accessible power source.EFFICIENT PERFORMANCEThe MAXIMA series is a completely self-powered, illuminated?exit sign requiring no external power source of any kind. The?MAXIMA series self-luminous sign is extremely reliable during?its predicted life. The MAXIMA series exit sign is always “ON”?requiring no wiring or electrical installation, and as a practical?and environmental matter, consumes no power of any kind. The?MAXIMA series life expectancy is 10 - 20 years, as specified.MECHANICAL SPECIFICATIONSThe MAXIMA series is manufactured under stringent quality?control procedures and is licensed by the Canadian Nuclear Safety?Commission and the U.S. Nuclear Regulatory Commission.?Illumination is achieved by using a permanent internal light source.?Tritium emits relatively low energy beta particles that bombardthe phosphorus coated glass tubes, this action generates light.?Light emitting phosphors are designed and selected according?to their color and light production efficiency. The MAXIMA series?features several glass envelopes (tubes) that are encased behind?plastic housing light diffusers. To reduce chances of breakage,the MAXIMA series features tritium tube shockproof mountings?made of PVC.
