Theatrical Lighting, 1,2,3
Planning a lighting package for small and medium theatrical spaces will be easier with the Altman Theatre Lighting Layout Guides, (small 48–channel guide, and medium 125–channel guides are available). Designed to be used as a starting point in examining the types and quantities of equipment to be specified and purchased, these guides include a light plot and an explanation of the layout/plot. A pictorial review of the types of Altman lighting instruments specified and a review of the lighting concepts that can be illustrated by placement of the luminaires as indicated on the plot are included. Within the guide, there is a color coding of the instruments and the definition is highlighted in the same color used on the plot. The definitions answer the ubiquitous "Why " and "What" questions, as in, why is this light necessary, and what will it do? Combining the introduction, with the explanation of "dividing the stage into areas" (there are nine for a small theatre and 15 for a medium–sized venue) and a thorough examination of the plot and its "shop order," a suitable lighting package and design for most theatrical performances can be achieved. Both the small and medium guide explain the relationship of "areas" to the recommended number of channels and dimmers, all in industry standard numbers, i.e., 125 control channels corresponds to a recommended 96 – 2.4kW dimmers. In addition, a complete kit of materials, specifications, and information is available for further review by budget and planning committees as well as facility managers.

Orders of Protection
The SX2120-SEQ provides guaranteed surge protection and power conditioning for up to 14 individual devices and the ability to sequentially power up/down electronic devices in separate groups. The 2RU (rack unit) enclosure features 14 standard grounded AC straight-blade receptacles that are divided into three groups of four, with two receptacles always on. Remote control for sequential switching is achieved via momentary switching, latching switches, or applied voltage (5-30VDC). In addition, an infinite number of units can be cascaded to operate either simultaneously, or in sequence. On the front is a backlit three–line LCD for the display of operating status and AC line voltage. All functions and time delays are programmable through an easy-to-use menu system, with programming commands being stored in non-volatile memory. All applicable standards are met, such as UL 1449 (1,000 surges—6,000V, 3,000 A) and US government guidelines, grade A, Class 1, model one).

Stop the Surge
As ethernet data networks become ubiquitous in facilities of all types, the need for reliability increases. The Leviton surge protective device was developed to provide transient voltage suppression for cards and devices operating on ethernet data networks. Grounding can be accomplished via one of two methods: a ground tab that facilitates connection to equipment ground frame systems, and a low inductance ground braid straps, for use when mechanical mounting constraints preclude the use of the metal ground tab. According to the manufacturer, the surge protective device offers dual redundant protection paths for transients entering into or out of the unit with automatic reset-PTC fusing. In addition, it provides low clamping voltages and the ability to withstand high transient current surges that may be encountered on ethernet PLC ports. RJ45 input and output connectors are used.
