How do I wire a DSC Motion Glass Break?

I bought a DSC Bravo 5 PIR motion/Glass Break unit model #BV-500GB. The install sheet is a little vague, what a suprise.
Do I wire the power like a 4-wire smoke?{Aux+, PGM with a reset attrib} Or do I use AUX+, AUX- and have power 24/7?
I ask as there is something about the Glass Break latching in the install sheet. I see that I have neglected to mention my control panel is a DSC PC1616. I have read that glass breaks are not easy to test so I suspect I will not know if I set it up well til' I have a trigger. Any info would be welcome.

Thanks mates, Rob

Glass breaks don't need resettable power, they use straight Aux power.

In the case of this device, there are actually 2 alarm relays in this thing. One for motion and one for glass break detection.

You can either wire them as separate alarm circuits, or wire them in series as a single circuit. (The first option requires an additional pair of wires between the alarm panel and the device, for a total of 6 conductors)

Glass breaks are only difficult to test if you don't have the instructions for the test procedure. Some are tested with a simple hand clap, others require moving jumpers and dip switches around.
