- Amendment #1: Extend due date to October 21, 2011 5:00 PM ET Amendment #2: Extend due date to November November 10, 2011 Please provide manufacturers, model numbers and pricing for the following: Chemical Fume Hood Alarms Must have: 1) have a pressure-independent flow-monitoring device connected to a local audiovisual alarm within the laboratory area. 2) when the fume exhaust falls below a preset safety level, the alarm will sound and the alarm light will come on. 3) all parts that are to be in contact with vapors/fumes in the hood, i.e, the sensing device, wiring etc., shall be chemically resistant. 4) alarm systems shall be UL approved 5) There shall be a means to shut off the audible alarm to reset. The alarm shall have an internal timer so that the audible alarm is reactivated after a specified time (adjustable between 5 minutes and 15 minutes) 6) The alarm shall have the capability to set the controller's setpoint to the safety level desired. 7) There shall be a means for setting the controller's setpoint to the exhaust level desired. This adjustment shall be "internal" so that it is not readily adjustable by operating personnel. Upon return to normal flow, the alarm shall sound again until reset. 8) Provides a local audible and visual alarm device capable of detecting a drop or rise in airflow (not static pressure) through the hood. That is, if the exhaust volume falls below or rised above preset exhaust levels, the alarm will sound and the alarm light will come on. 9) The monitor shall use dual thermistor or dual diode sensing system to measure the velocity. 10) The sensor must be mounted in a flow tube placed on either side wall or front face of the fume hood but not within the hood sash opening itself. 11) Local Audible and visual alarm must have capabilities for remote monitoring hook up. 12) Provide a means to shut off the audible alarm and to reset. The alarm shall have an internal timer so that the audible alarm is reactivated afer a specified time (adjustable between 5 minutes and 15 minutes) The silence device shall not turn off the warning light. 13) Provide a means for setting the alarm set point to the exhaust level desired. This adjustable shall be "internal" so that it is not readily adjustable by operating personnel. 14) All parts of the system which are apt to be in contact with vapors or gases in the hood shall be chemically resistant, i.e., the controller, sensing device, wiring, etc. Also, Please let me know how your model is protected from the operators permanently silencing the alarm or changing set points easily.
