*	NOTE: Does not apply to this product.
**	NOTE: The process of 'Chaining' or 'Spoking' multiple switch sensors together is sometimes possible although NOT recommended by AVTECH. There is no individual sensor alerting when multiple sensors are 'Chained' or 'Spoked' from a single switch sensor channel. If multiple sensors are connected to a single switch sensor channel, they should typically ALL be 'Normally Closed'.
***	NOTE: The first year of MSUS is always provided without charge. Optional extensions of the MSUS are available on an annual basis. This line item is the renewal rate for a 12 month extensions of this model. As your organization licenses additional units, the per unit cost for this service is reduced. Significant decreases occur after 5 and 10 units . Call a Product Specialist for more information or a quote. Multi-Year quotes are available at discounts (20% - 2nd yr, 30% - 3rd yr, 40% - 4th yr, 50% - 5th+ yr).
