B1272M001 BARNETT ENGINEERING LTD. ProTalk Cv2
Figure 3 Packaged Cv2
2 Installation
The Cv2 can be installed before or after the configuration has been transferred from the PC to the
unit. If the Cv2 is configured in the shop before it is installed in the field, all of the programmed
parameters and voices will remain unchanged in the unit’s non-volatile flash memory.
2.1 Antenna requirements
The antenna used for your installation will depend on the proximity of the alarm unit to the
cellular carrier facility. If the installation is very close to a cell site, a portable style antenna
can be connected directly to the RF connector on the Cv2. If the distance between the
installation and the nearest cell site does not provide adequate signal strength to operate with
the small antenna, then an outdoor or other high gain antenna will be required. Antenna
system details for this type of antenna installation -- antenna type, height and coaxial cable
type -- will depend on the particulars of the site.
If you use the directly connected antenna, it should be oriented vertically.
2.2 Mounting
The Cv2 is available in two versions: the packaged unit which is housed in an enclosure
complete with a battery backed power supply and a programming phone set, or the stand-
alone version which is the Cv2 alarm reporter without the above accessories.
2.2.1 Packaged model
The packaged model should be mounted
onto a wall or other vertical surface in a
location where the temperature cannot
exceed the Cv2 rating.
Before connecting AC power, confirm that
the setting of the voltage range switch on the
power supply module is set for the correct
input, either 110 or 220 VAC.
Connect AC power to the terminal strip on
the power supply module. Connect the
antenna or coaxial feed line to the remote
antenna onto the TNC coaxial jack on the
Cv2.
Connect the input and output signal lines
between the Cv2 and the equipment that you
want to monitor and control. Details of the
input and output ports are discussed later in
this chapter.
