[intruder alert! intruder alert!  Ha Ha Humanoid!]

I have specs for a PIR (Passive InfraRed detector).
They are made by Raytek Inc, a member of the Hoermann Group
(whoopie-doo!).  800-227-8074.

Specifications:
mounting: ceiling (recessed or surface)
	[yes I know, you don't have a ceiling over your yard so
	 take this for what it's worth]
range:		16 feet
pattern:	21 degrees by 43 degrees in 10 segments
input voltage:	12-24 V D.C.
Current:	10 ma
Output:		Form C relay 1 A at 30 VDC
Operating Temperature:  -30 deg. F to 150 deg. F
Construction:	high-impact thermoplastic
Dimensions:	model 410 - 2-7/8 x 5" dia.
		model 430 - 2-7/8 x 6.5" dia.
Weight:		1.5 lbs

Operation and coverage:
	Raytek 410 and 430 Trap Detectors operate by sensing changes
in infrared energy levels within the detection pattern.  When a person
enters the protected area his body heat abruptly changes the infrared
energy level and triggers an output from the detector.

	The alarm relay has a built-in alarm timer.  This is used to
extend relay dropout time for special applications, such as access
control.  The relay may be held in the alarm state for any length
of time between 1 and 30 seconds.


The rectangular field it covers is divided into 10 zones, 5 by 2.
You can select which ones to use to avoid areas which will cause
false triggering.
