2.3.2 +12 volt alarm signal

The input will accept an alarm signal that switches between 0 and +12 volts with the wiring arrangement shown in Figure 5.

If the signal switches between +12 volts and an open circuit, as in the case of a relay contact, the ‘B’ terminal must be connected to ground to ensure that the logic level goes to ground when the voltage is removed.

Figure 5 +12 Volt Input Wiring

2.3.3 +5 volt alarm signal

Figure 6 shows how an alarm signal that switches between +5 volts and ground is wired. If the alarm signal does not have a true ground level, terminal ‘B’ must be connected to ground.

2.3.4 Analog input

For analog signals, either of the wiring configurations shown in Figures 7 and 8 can be used. The connection shown in Figure 7 will provide additional filtering of the signal.
