BusSecure User Manual DVR Installation and Wiring
0150-0263A / May 2003 19
3.2.2 ALARM AND TRIGGER INPUTS The BusSecure system allows for four inputs, which can be defined as either triggers or alarms. The
Impact Sensor and Panic Button are both examples of alarm inputs. When the trigger is activated, it will
open the normally closed connection, activating the alarm. Refer to the system specific layout for the
location and types of inputs used in your installation.
1) Remove the P2 terminal block ( in Figure 22) from the rear panel assembly by loosening its
mounting screws and pulling it out of its socket.
2) Each trigger device must have a normally closed connection with the DVR and be connected as
shown in Figure 25. All wires should be stripped 3/8 of an inch.
Note: Terminal 18 also may be used for a panic button or impact sensor (up to three wires can go into terminal 18).
