3.2.2 Vertical Mounting
Vertical mounting illustrations
When the VTO is vertically mounted, make sure that the tamper switch on the rear panel
(marked with "1" in Figure 3-5) is retracted so that once the VTO is dismantled, tamper switch
will be released, and then alarms will be triggered. The alarm will keep ringing for 15 seconds.
Cascade Connection
To make modules work collaboratively, cascade connection is needed. See a cascade
connection example in Figure 3-7.
