COMMERCE BUSINESS DAILY ISSUE OF MARCH 26,1997 PSA#1810DOC; Mountain Administrative Support Center; Acquisition Management
Division; 325 Broadway MC3; Boulder, CO 66 -- TOXIC/PYROPHORIC/FLAMMABLE GAS DETECTOR SYSTEM SOL 814704153BJ
POC B J Roberts (303) 497-3799 E-MAIL: NOAA; MASC Acquisition
Management, Joyce.J.Mills@noaa.gov. The Electromagnetic Technology
Division of NIST requires a networked, modular
toxic/pyrophoric/flammable gas detection system to monitor a laboratory
containing a bank of LPCVD furnaces. The system must be flexible,
easily expanded to handle additional gasses and monitoring points, and
networked. For safety and accuracy, we require a system which places
sensors directly at the sampled space and which does not rely on
sampling pumps or sampling tubes. We require three (3) sensors each for
SILANE, DICHLOROSILANE, AMMONIA and HYDROGEN. One of each sensor type
will be mounted on the individual gas cabinet, one of each sensor type
will be mounted to sample furnace room air, and one of each sensor
type will be mounted to sample a common exhaust duct. Duct and cabinet
mounted sensors shall be qualified for use in high air flow
environment (few hundred CFM airflow). The sensor head electronics
shall be self-checking, self-calibrating when sensor cell is replaced,
and interchangeable between different sensor types. The sensors shall
be capable of continuous, direct measurement of specific gas species.
Sensitivity levels shall cover the range of 1-2 times the TLV for
toxics and pyrophorics and 0.2-0.7 times the LEL for hydrogen. It shall
be possible to expand the system simply, both in terms of points
sampled and different gasses (particularly PHOSPHINE). The system shall
be provided with all required power supplies, networked output relays,
and interface electronics and configured to provide the following
functionality. (a) Relays/junction boxes to signal: (1) Low level
detect alarm enable, (2) High level detect alarm enable, (3) Output to
building fire alarm system (High and Low level alarm for each sensor
and Trouble for each sensor), (4) Any sensor in alarm signals gas
shutdown, and (5) Any sensor in alarm signals "shut down tool". (b)
RS232 interface electronics and basic network configuration software to
allow connection of detector system to PC (PC and visualization
software will be provided by NIST). No RFQ package will be made
available. Responses are due April 7, 1997. For technical questions,
call James Beall 303-497-5989. (0080) Loren Data Corp. http://www.ld.com (SYN# 0330 19970326\66-0002.SOL)
