The ProtectArt 2000 is intended as a museum case temperature and humidity Alarm, monitor and logger. If the case deviates from the programmable limits, the Protect-Art system will indicate an alarm condition via an externally mountable LED. ProtectArt 2000 safeguards priceless collections and provides an accounting trail for curators and insurance companies.
While the ProtectArt 2000 was designed for use by museums, many other applications exist where humidity and temperature needs to be monitored and creating a recorded log is advantageous.
Plugging Protect-Art into your computer, allows one to set low and high trip points for temperature and humidity along with other settings. Once alarm points are set up, the external LED will light and blink if the safe range is exceeded. A magnetic sensor allows initiation of a self test without opening the display case.
Protect-Art also logs temperature and humidity allowing one to create graphs to spot long term trends and to prove environmental quality is maintained during transport and inter museum loans.

|Time base||+/- 20ppm logged from internal clock (approximately 5 minutes over 3 months)|
|Calibration data to be stored on sensor PCB ???|
|Magnetic test switch||For activating self test without opening case (hold a magnet near by.) When activated, causes remote indicator LED to light solid (not blinking) if no alarm conditions are present. If alarm condition is present, indicator LED will be blinking, indicating an alarm condition. Normally mounted inside display case.|
|External Alarm LED||Remotely mounted LED blinks during alarm conditions. connected via included 3.5 mm phone style connector. This output can be configured as an alarm contact - inquire for details.|
|System Status LED||Tri-color LED used during firmware updates ??|
|Sensor||3.5 mm phone jack - a small and easily hidden single sensor for both humidity and temperature|
|Self Test switch||magnetic test-switch via 3.5 mm phone jack cable - operates though glass or wood case wall.|
|Remote LED||3.5 mm phone|
|Computer Interface||DB9 RS232 serial via 5’ DB9 to DB9|
