The Trooper™ Basic Installation and User’s Guide 8
6. Alarm Cable and Switch
The Trooper™ TR4-10 DVR has a valuable feature that allows for easy
searching of events in the recorded video. An Alarm Event can be used to set a
search point in the digital video and can be triggered from a number of different
sources, including a driver-activated switch. A 20-foot Alarm Input Cable is
provided that plugs into the Alarm Input Connector on the back of the DVR.
Connecting the red and black wires from the Alarm Input Cable together will
activate the Alarm Input. Alternatively, connecting the red wire to electrical
ground can also activate the Alarm Input.
A red push-button Alarm Switch is also provided. This switch mounts into a ½”
hole and is attached to the Alarm Input Cable using the two butt splice
connectors supplied. The black wire from the Alarm Switch attaches to the black
wire in the Alarm Input Cable, and the blue wire in the Alarm Switch attaches to
the red wire in the Alarm Input Cable.
7. EZT Decoy System
The EZT Decoy System uses a live camera that does not have to be changed
from bus to bus - only the DVR must be removed. For decoy systems, the lock
box and all the harnesses and cables are installed the same as for a live system.
