3.0 Setup
3.1
Setting P3
A shorting link on P3 selects the voltage and
current applied to the alarm panel's telephone
circuit to simulate the signal from a PSTN
telephone exchange. For most alarm panels, set
the shorting link to the H position (short the middle
and right pins of P3). The L position results in
slightly lower power consumption for the C900V2
but some alarm panels might report a telephone
line failure when dialing the C900V2.
For UL approved applications, the
shorting link must be set to the H
position.

Setting the DIP Switches
A ten-position DIP switch programs the C900V2.
The programming depends on the application and
dialer format of the control panel connected to the
module.

Because the C900V2 emulates a phone
line and a digital receiver, you must
program the C900V2 to the format it
receives from the control panel.
DIP Switch positions 1 through 4 and 10 program
the dialer format into the C900V2. Table 4 on page
9 lists the format programming for these DIP
switches.
