"Mount the Detector Anywhere - Mounts on any wall, in the window frame, or on
the ceiling, with no minimum range and a maximum range of 25? (7.6 m) to the
glass."

> ignor the part where the manufacturer says test with
> THEIR tester.

Actually, I sell the tester on the same page as the sensors.   The installation
instructions recommend the tester.

"9. Testing the Detector - The detector should be tested at least once each
year.  Test the detector with the FG-701 Glassbreak Simulator.  The model FG-700
Glassbreak Simulator can also be used if it is set for the tempered glass sound.
Other simulators will not give accurate indication of range."

The detectors come with easy to read instructions about placement, testing, etc.
For example:

"2. Choosing Mounting Location - The preferred mounting location for the device
is on a wall or ceiling, opposite the protected glass. For the best detector
performance, select a mounting location that is:
? within 7.6 m (25 feet) of the protected glass;
? within clear view of the protected glass;
? at least 2 m (6.5 feet) from the floor;
? at least 1 m (3.3 feet) from forced air ducts;
? at least 1 m (3.3 feet) from sirens or bells greater than 5 cm (2 inches) in
diameter.
? between the protected glass and any heavy window coverings that may be
present.

Alternatively, when heavy window coverings are present, the detector can be
mounted on the frame of the window.

Avoid mounting the detector on the same wall as the protected glass, on
free-standing posts or pillars, or in rooms with noisy equipment (air
compressors, bells, power tools, etc.), if this equipment is operated when
the detector is armed."

The instructions show how easy it is to test a given location before running a
wire:

"3. Testing Mounting Location With 9V Battery You may test the detector in the
desired mounting location before drilling/wiring.  If the 9V battery cannot
supply sufficient power, the detector will not operate and the red and green
LEDs will flash on/off.  Follow the procedure described in ?Testing the
Detector? (next column) to confirm proper operation."

Perhaps the reason you don't believe that a DIYer can do this is you don't
expect them to read the instructions.  I must admit that it is a good idea to
read the directions which come with the equipment.  Not doing so can lead to
errors and systems that work as poorly as some of the professionally installed
systems that my DIYers have had to replace.
