8. PART EIGHT - PRE-INSTALLATION GUIDE
8.1 OPERATING CONDITIONS
Be sure that the following operating condition limitations will not be exceeded for the paging terminal
location.
8.1.1 Power

Power conditioning is suggested. Remember, it takes the paging terminal approximately 2 minutes to
boot up, so each brown-out or power failure will make the system inoperable for up to 2 minutes.
8.1.2 Ambient Temperature

+40 to +120 degrees Fahrenheit. +5 to +50 degrees Celsius.
8.1.3 Humidity

8% to 80% relative humidity, non-condensing.
8.1.4 Altitude

10,000 feet (3,000 m).
8.2 MOUNTING

The Model 2100 main chassis is 21" tall, 17" wide, and 5.5" deep. The Model 2200 main chassis is
30" tall, 22" wide, and 7" deep. The expansion chassis is 21" tall, 22" wide, and 7" deep. The main
and expansion chassis’ generally need to be located adjacently, either side by side or one on top of
the other.

The terminal should be mounted to a wall, using the pre-drilled holes and the provided lag bolts.
8.3 WIRING
Because each terminal installation will have its own wiring layout, no specifics are given here. However, a
few rules are given to help with the wiring.
* The lengths of cabling should be kept to a minimum, the longer a cable becomes, the chances of RF
interference increases.
* The wiring should be neat.
* When wiring a group of connections, the first connection should be done and tested before doing the
entire group.
* Mounting all punch down blocks, etc. onto a sheet of plywood is suggested. This makes it possible to
wire up the equipment in the shop where it is easier to work on.
* The wiring should be done and tested prior to going live.
* Grounding of the paging terminal is extremely important. This Pre-Installation Guide makes no
attempt to cover all issues concerning grounding.
8.4 RADIO TRANSMITTER

All RF level adjustments and interfacing should be made prior to installation of the terminal.
