Safety and security equipment maker Quintron Systems of Santa Maria, Calif., recently received two orders from NASA’s Stennis Space Center in Mississippi worth a combined $350,000 for multichannel communications equipment used in rocket engine test environments and other hazardous areas.

Quintron said in a press release the orders were placed under a $4.1 million indefinite delivery, indefinite quantity contract Stennis awarded in 2008 for the company’s DICES Subsystem Multiplexer (Sub-MUX) equipment. Quintron has booked $1.35 million in orders under the contract to date.

The first of the two new orders includes additional Sub-MUX equipment for the A1 Test Stand at Stennis and 11 more user stations. The second order calls for Sub-MUX equipment for three test facilities at Marshall Space Flight Center in Huntsville, Ala.

The new orders follow an initial delivery to Stennis that included nine Sub-MUX chassis, 162 hazardous-duty wall-mounted user stations and 83 control room rack-mounted user stations.
