REMEMBER, IT'S ALL ABOUT COVERAGE!
Mounting
Install the included antenna by screwing it onto the connector at the top of the 7845CZ. The
final mounting site should be chosen so that:
•
wire lengths do not exceed the maximum wire lengths as specified in Table 6
•
minimum distance to other electrical devices is maintained
•
minimum signal strength level is observed
•
there is access to the 7720P programming port and tamper switch
•
all LED displays can be observed
•
antenna is free from any interference.
Once the 7845CZ has been installed, programmed, and tested, anchor the radio permanently
to the wall using the screws included with the radio. Use the 3 mounting holes as shown in
Figure 3. All 3 mounting holes must be used. It is important to attach the unit securely so
that it cannot be removed or accidentally knocked off the wall after installation.
NOTE: The third mounting hole located behind the antenna is not shown in Figure 3.
