2.2.2 Stand-alone model

The stand-alone Cv2 can be mounted on a flat surface. Make sure that there is enough room around the unit to make connections. The environment should be clean and dry, with an

ambient temperature that does not go below -20oC or above +50oC.

Connect a DC power

source to the terminals on

TB2. The Cv2 requires up

to 1.5 Amps to operate;

the supply should be sized

accordingly. Input power

to the unit is protected by

a Polyswitch current limiter. If a fault develops in the CV2, this switch will become a high

resistance to prevent damage to the equipment or the power supply. Once this switch has been activated, the fault must be removed before it will reset and allow current to pass through to the equipment.

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 in the next section.

2.3 Input port connections

The input ports can be connected to a variety of contact or voltage sources for monitoring purposes. Select a wiring configuration that matches your alarm source from one of the following arrangements:

2.3.1 Ground closure alarm signal

For alarm sources that appear as a ground closure, either through a mechanical contact or an open collector driver, the input should be wired according to Figure 4. If the input is normally open and goes to ground during an alarm condition, program the Hardware section for this input as “Normally High”. If the reverse is true, set the input to “Normally

Low”.
