If you are interested in the following device, please send a mail message
and I will attempt to provide full scale literature.  This is a survey to
see if a special product that was constructed several years ago should be
resurected.

ENVIRONMENT SHUTDOWN SYSTEM.

This is a simple little box that interfaces to the DR11 family of parallel
interfaces.  It provides the following things.
1.  Digital Readout of Current Temperature.
2.  Digital Readout of Current Relative Humidity.
3.  Digital Readout of Current AC Line Voltage (averaged over a short
	interval.
4.  Hardwired shutdown waring signal.  Provided 1-10 secs (programmable,
	perhaps up to a desired time) warning if a preset limit is exceeded.
5.  Hardwired shutdown relay contact.  Suitable for driving a shunt current
	trip.  This is double action, and has been designed to be relatively
	failsafe.
6.  A couple of other relay or contact inputs, suitable for interfacing to
	a fire alarm system, that can be used as additional shutdown signals.

The box itself is relatively inexpensive, the digital temp and humidity
gadgets will take your breath away.  I will send plans to people who have
serious enquiries,  along with estimated costs.  Note that this little
gadget is not repeat not Underwriters Approved, and you may have some
funny problems with your insurance company if you use it!
