Hello,  
	I believe that my PIR is failing, and I'd like to replace it with an equivalent PIR.  Specifically looking for curtain PIR, small form / factor, operates on approx. 9-16 VDC (I have an existing 12V power supply.  Will be mounted outdoors under eaves and well protected from weather.  Need approx. 40" "look-out" range as vertical curtain.  The item being replaced is a Visonic CH-1000.  
	Thx,  
	Jim
